Overview of Google Earth & Maps This guide will help you develop intriguing Google Earth content for your organization. It includes useful information about creating content, as well as step-by-step exercises to help get you started! Why use Google Earth & Maps? • They are powerful interactive tools for communicating your organizations’ projects. • They are easy to use. • They are designed for users who are not highly technical or map experts. • They are a way to store, visualize, and distribute geographic data and information. How are Google Earth & Maps different? Google Earth is… • 3-dimensional • Viewed in the Google Earth application (which is downloaded and installed) • Users must be connected to Internet at first, but some data can be “cached” for off-line use. Google Maps is… • 2-dimensional • Viewed in a web browser (e.g. Mozilla Firefox, Google Chrome, Apple Safari, Internet Explorer) • Users must be connected to Internet to view your map. Google Earth Plug-in is… • 3-dimensional • Viewed in a web browser (e.g. Mozilla Firefox, Apple Safari, Internet Explorer), although users must download a browser plug-in the first time they ever view Google Earth in a browser. • Users must be connected to Internet at first, but some data can be “cached” for off-line use. © 2010 Google 3
Introduction to Using and Creating Content in Google Earth What is Google Earth? Google Earth is a software application you install on your PC or Mac computer, which allows you to explore the world and its rich geographic information electronically. There is also a Google Earth Plug-in for the browser that allows you to embed Google Earth in your website. For these exercises, you will be using the application installed on your computer. Much of the data, including the imagery, roads, borders, and other information are stored on Google servers and the software dynamically downloads only the data you are viewing. For this reason The imagery in Google Earth is not in real-time -- most of the data was acquired 1-5 years ago. © 2010 Google 4
Navigating in Google Earth To navigate in Google Earth, use the navigation tools in the upper-right corner of the 3D viewer. 1. Rotate the map by clicking and dragging the gray ring around. To return the map to north as pointing up, click the once. 2. Move your view, or tilt the viewer and look around from a different perspective, by clicking the arrows around the eye. 3. Move (or "pan") around the map, by clicking the arrows outside hand. 4. Zoom in or out on the map, by clicking and dragging the zoom slider. You can also click on the zoom in or out buttons to zoom in, or double-click these buttons to zoom in or out all the way. You can also use your mouse! Navigate by double-clicking with your left mouse button (to zoom in) or your right mouse button (to zoom out). You can also use the mouse wheel to zoom in and out. © 2010 Google 5
Exploring Google Earth Panels The Search panel Use the Search panel to search for places, businesses, organizations, and cities, and to get directions. 1. Use the Fly To tab to search for places, including: • Cities and addresses • Places of interest (parks, monuments, etc.) • Coordinates (latitude, longitude) 2. Type nairobi, kenya into the search box, and click the search button: 3. Use the Find Businesses tab to search for business, or organizations. Type in a business or organization to search for it. 4. Use the Directions tab to search for directions between two places. Find directions between your organization and Google, or between two cities. 5. Clear the search results and start over by clicking the clear button: © 2010 Google 6
The Layers panel Use the Layers panel to view the permanent layers in Google Earth, including borders, roads, and other data. Please note: • Layers are viewable in the Layers Panel by everyone who has Google Earth. Some of it is dynamic, and is updated automatically over time. Some of it is static, and does not change. • Most of the data layers are licensed from data providers and are LOCKED (you don't have control over it), including Roads, Border and labels, and Terrain. • Some of the layers are created by users, including Panoramio and Wikipedia (under Geographic Web), and the Google Earth Community and YouTube (under Gallery). © 2010 Google 7
The Places panel Use the Places panel to organize and save your places that you visit, your favorite locations, address or listing searches, and more. The Places panel is also where you view your own Google Earth data that you've created, and other people's Google Earth data that you've downloaded from the Internet. All data located in the My Places folder is saved for subsequent Google Earth sessions. When you quit Google Earth, and start it again, the data will still be under My Places. Data located in the Temporary Places folder are temporary, and will not be saved for the next time you start Google Earth again. To move data from Temporary Places to My Places, click-and-drag each item to the My Places folder. The data will now be saved in Google Earth. Data in the Places panel are viewable only on the computer you are using. This is similar to viewing a document in Microsoft Word – the file is not online and public to the world – you are simply viewing a file on your computer. © 2010 Google 8
Adding existing content to Google Earth To find data to add to Google Earth, use the Add Content button in the Places panel to link to the Google Earth Gallery. You must be connected to the Internet to use this button! 1. Click on the Add Content button in the Places panel. An Internet browser opens in a frame within Google Earth. The Google Earth Gallery webpage opens. 2. Click the button at the top right corner of the Internet frame to open the Internet in an external frame, which will open the same page in your Internet browser application. 3. In the browser pane, search for Africa or another location or topic to search the Google Earth Gallery for project files about that location or topic. These are Google Earth projects that other people have created in Google Earth and then uploaded to the Google Earth Gallery webpage. 4. Find a project you would like to view in Google Earth, and click the link The Google Earth KML project file is loaded into your Temporary Places in the Places panel. © 2010 Google 9
To open and view a Google Earth project file that exists on your computer: 1. Go to the File menu, and choose Open... 2. Navigate to a KML file on your computer, and click Open. The KML file will be added to your Places panel. If you have My Places selected at the time your open the file, the data will be added there. If you have Temporary Places selected, it will be added there. © 2010 Google 10
3. Click on a volcano placemark. A balloon opens, displaying information about the placemark you clicked on. A balloon is a window that can display text, images, movies, tables, graphs, and other information about a location. 4. Click on other volcano placemarks to view information and images about other volcanoes. © 2010 Google 11
Annotating Google Earth with placemarks, paths, and polygons Google Earth makes it easy to create a map with annotations such as data and information about your projects. You can add placemarks (points), paths (lines), polygons in Google Earth, and add text, images, and videos to the pop-up balloons. You can then share it with multiple people! For this tutorial, we will use an example of Bristlecone Pine Tree research in the White Mountains. The images and videos, as well as the inspiration for this tutorial example, are from Adelia Barber's work at the White Mountain Research Center. Read more about her work in the Google Earth Outreach case study (http://earth.google.com/outreach/cs_adelia.html). Let's get started! 1. Open Google Earth on your computer. 2. In the Search Panel, enter "White Mountains, CA" into the Fly To box, and click . Google Earth will fly you to the White Mountains. © 2010 Google 12
3. Find the toolbar above the 3D viewer: 4. Each button on the toolbar has a purpose. Find the tools for create a placemark, path, and polygon: Let's add data! © 2010 Google 13
Add placemarks 1. Click the Add Placemark button in the toolbar. A placemark is automatically added to Google Earth. Also, a New Placemark dialog box appears. 2. Move your placemark's location by clicking and dragging its icon, or by typing a latitude and longitude into the New Placemark dialog box. 3. In the New Placemark dialog box, type in a name for the placemark in the Name field. In this example, we typed "Bristlecone Pine Tree". 4. Type in a description for the placemark in the Description field, which will be displayed when a user clicks on the placemark. In this example, we typed "This is one of the world's oldest living trees." 5. Click on the icon button in the top-right corner of the window, and choose an icon for your placemark and press OK. In this example, we chose a tree icon. You can also click on Add Custom Icon... to use a custom icon, such as your logo. © 2010 Google 14
6. Click on the Style, Color tab, and choose a color, scale (or size), and opacity for the placemark icon and label text. In this example, we choose to change our label color to green. 7. When you are finished creating your placemark, click OK and your placemark will appear in the Places panel. When you click on your placemark's icon or hyperlinked name in Google Earth, a pop-up balloon will appear with your placemark's name and description. © 2010 Google 15
Tips: • To edit a placemark's location, name, or description, right-click on the placemark in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). Click-and-drag the icon to change the location, or edit the name and description and click OK. Add paths 1. Click the Add Path button at the top left of your map. A New Path dialog box appears, and your cursor changes to . 2. Click on a series of places on the map form a path. Each time you click, a new node is added to your path. You can also click-and-drag to create frequent nodes, which makes a smoother path. In this example, we will create a path marking the tree line. © 2010 Google 16
3. In the New Path dialog box, type in a name for the path in the Name field. In this example, we typed "Tree Line". 4. Click on the Style, Color tab, and choose a color, width, and opacity for the path. In this example, we choose a dark green color, a width of 5.0, and an opacity of 75%. Tips: • To play a tour of the path and fly along its route, click the Play Tour button: • To edit a path's location, name, or description, right-click on the path in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). Then you can edit the title and description and click OK. Right-click your mouse to delete recently-created nodes. You can also click- and-drag any nodes to reshape the path. © 2010 Google 17
Add polygons 1. Click the Add Polygon button at the top left of your map. A New Polygon dialog box appears, and your cursor changes to . 2. Click on a series of places on the map to form a polygon. Each time you click, a new node is added to your polygon. You can also click-and-drag to create frequent nodes, which makes a smoother boundary to your polygon. In this example, we will create a polygon around the White Mountains (you may have to zoom out to see the entire mountain range). 3. In the New Polygon dialog box, type in a name for the polygon in the Name field. In this example, we typed "White Mountains". 4. Type in a description for the polygon in the Description field, which will be displayed in the polygon's pop-up balloon. In this example, we typed "The White Mountains are home to Bristlecone Pine Trees." 5. Click on the Style, Color tab, and choose a color, width, and opacity for the boundary lines. Choose a color and opacity for your polygon area, and determine if you want the polygon filled and outlined, only filled, or only outlined. In this example, we chose green colors, a line width of "10.0", and medium opacities. 6. Click on the Altitude tab, and change the altitude mode to "Relative to ground" (not "Clamped to ground"). Then move the slider to increase altitude, or height, of the polygon if desired. Check the box to extend the sides, or walls of the polygon, to the ground. © 2010 Google 18
Tips: • To edit a polygon's location, name, or description, right-click on the path in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). Then you can edit the title and description and click OK. Right-click your mouse to delete recently-created nodes. You can also click- and-drag any nodes to reshape the polygon. • Polygons can be used as 3D bar graphs in Google Earth. One example is the USHMM’s Crisis in Darfur layer, which uses polygons to represent number of refugees and displaced people. © 2010 Google 19
Organize your places with folders 1. To add a folder, go to the Add menu and select Folder. 2. In the New Folder dialog box, type in a name for the folder in the Name field. In this example, we typed "My Google Earth Project". 3. Click OK. Your new folder is added to the Places panel. 4. Click-and-drag each place (your placemarks, paths, and polygons) into the folder to organize your project. Tips: • To play a tour of all the items in the folder, click the Play Folder button: • To edit a folder's name or description, right-click on the folder in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). © 2010 Google 20
Embed images in your balloons Google Earth balloons can be customized using HTML. You can add font sizes, styles, and colors, links, tables, and images into your balloons by including it as HTML in the Description. 1. Choose a placemark you've already created, such as the placemark created earlier in this tutorial. 2. To edit the placemark, right-click on the placemark in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). 3. Copy and paste the following HTML code into the Description field of your placemark. It references a photograph of a bristlecone pine tree that is online. 4. Click OK to finish editing the placemark. 5. Click on the placemark in the 3D viewer, and you will see the image in the placemark's balloon! Tips: • If you want to embed an image from your computer’s hard drive, simply type or paste in the image’s file path. For example, to embed a picture from your ‘My Pictures’ folder, type in: © 2010 Google 21
6. To add more content to your balloon, such as text and links, you can use more HTML code tags, such as the following code: For more information about Bristlecone Pine trees, see the White Mountain Research Station 7. Click OK to finish editing the placemark. The placemark's balloon now has the image, as well as text and a link! Tips: • You can use a program like Adobe Dreamweaver or freeware NVU to preview the balloon design as you edit the HTML code. • You can also upload all of your photographs to PicasaWeb, and click the link. Then copy the embed code, and paste it in your balloon’s Description field to embed your photos from PicasaWeb into your balloon. © 2010 Google 22
Embed YouTube videos in your balloons You can easily embed a YouTube video into a placemark balloon in Google Earth. 1. Upload your video to YouTube (http://www.youtube.com) or choose a video that's already uploaded. 2. On the YouTube video's webpage, find the Embed field. Click in the Embed field to select it, and copy the HTML code there. The code looks similar to this: 3. Choose a placemark you've already created, such as the placemark created earlier in this tutorial. 4. To edit the placemark, right-click on the placemark in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). 5. In the Description field, paste the YouTube HTML code which you copied in Step 2. © 2010 Google 23
6. Click OK. 7. Now when you click on the placemark, its balloon has the YouTube video! © 2010 Google 24
Save your project and share with others Google Earth allows you to save your project to your computer in the .kmz file format. 1. Right-click on your project folder, and select Save Place As... or click on the folder and then go to the File menu, and select Save Place As... 2. Enter a name for your .kmz file, and click Save to save it to your computer. You will now find your KMZ file on your computer. You can share the map you created by emailing the .kmz file to your friends and co-workers, posting it on your website with a link to download it, or embedding it with Google Earth on your website or blog (see the Embedding Earth into your Website section). Tips: • A Google Earth project file is a KML file, with a filetype extension of .kml or .kmz. KMZ files are compressed files that are smaller than KML files. If you used any custom images or photos from your computer, Google Earth will include them in compressed KMZ files so that others can see them too. We recommend saving your Google Earth projects as .kmz for a smaller file. • When you save your Google Earth KML project file to your computer, it is private. If you upload the file to a web server, or e-mail it your friend or colleague, then it is no longer private. This is similar to putting any file, such as a PDF file, up on the web or e-mailing it to someone. © 2010 Google 25
Creating Photos & Image Overlays in Google Earth In Google Earth, you can easily drape your own images or maps over the terrain, as well as overlay your photographs in the places they were taken to create a photographic tour! For this tutorial, we will use the example of draping a scanned trail map of Glacier National Park as an image overlay, and placing a photographic overlay of Grinnell Point at sunset, in Glacier National Park, USA. The images used in this tutorial, including a map of Glacier National Park and a photograph of Grinnell Point are both from Wikimedia Commons. Let's get started! 1. Open Google Earth. 2. Zoom to the area where you want to overlay your map. For this example, search for "Glacier National Park, USA". Google Earth will automatically zoom you into the Glacier National Park area. 3. For this exercise, make the Terrain layer visible. Go to the Layers panel, and scroll to the bottom. Check the box next to Terrain to make it visible. Also, it is a good idea to make the Parks and Recreation Areas layer visible. To do this, expand the folder Places of Interest, and then check the box next to Parks and Recreation Areas. © 2010 Google 26
4. Find the image overlay tool in the toolbar. Later, you'll use the Add menu, and select Photo. 5. Now, let's add overlays! Add an image overlay 1. Click the Add Image Overlay button to add a new image overlay. A New Image Overlay dialog box appears, and a green outline is placed on the Earth. 2. In the New Image Overlay dialog box, type in a name for the image overlay in the Name field. In this example, we typed "Glacier National Park Map". 3. Copy and paste the link below into the Link field, or click "Browse..." and find an image to add from your local hard drive. In this example, we will use the following URL from the Internet: http://upload.wikimedia.org/wikipedia/commons/3/31/Map_of_Glacier_National_Park.jpg 4. Move the Transparency slider to the left to make the image a little transparent, which will assist you in placing the image in the correct location. Use the park boundaries to help you align the park boundaries on the map with the boundaries in Google Earth. © 2010 Google 27
5. Use the center cross-hair marker to move the image overlay on the globe and position it in the right location. 6. Use the triangle marker at the left to rotate the image for better placement. 7. Use any of the corner or side anchors to stretch or skew the selected corner or side. If you press the Shift key when selecting this marker, the image is scaled from the center. 8. Click OK when you are finished. The map is now listed in the Places panel, and can be saved to a KML file with other Google Earth project data you have created. © 2010 Google 28
Add a photo overlay 1. Zoom to the area where you want to overlay your photograph. While you are in Glacier National Park, search for "Grinnell Point". Google Earth will automatically zoom you to Grinnell Point. You may choose to make the Mountains and USA Features layers visible in Google Earth. To do this, go to the Layers panel, scroll to the bottom, and expand the folder Places of Interest, then Geographic Features, and then check the box next to Mountains and USA Features. 2. Orient the view (heading and tilt) to match the heading and perspective of the photograph of Grinnell Point that we will be adding to Google Earth. You want to be looking at the same view in Google Earth that the photographer was looking at when they took the photograph. In this example, we will tilt Google Earth so we are looking at Grinnell Point. © 2010 Google 29
3. Go to the Add menu, and choose Photo. A New Photo Overlay dialog box appears. 4. In the New Photo Overlay dialog box, type in a name for the image overlay in the Name field. In this example, we typed "Grinnell Point at Sunrise". 5. Copy and paste the link below into the Link field, or click "Browse..." and find a photograph on your local hard drive. In this example, we will use the following URL from the Internet: http://upload.wikimedia.org/wikipedia/commons/9/92/Grinnell_Peak_Sunrise.jpg © 2010 Google 30
6. Move the Transparency slider to the left to make the image a little transparent, which will assist you in placing the image in the correct location. Adjust the Earth's position behind the photo by using the Look joystick to change your perspective, as if you were slightly turning your head. 7. Click OK. The photo has been added to Google Earth in the location you set. Now, when people double-click on your photo's camera icon in the 3D viewer or Places panel, they will be flown into the photo. Notice how the navigational tools change into photo navigation tools so you can get inside and explore the photograph! © 2010 Google 31
Importing Global Positioning Systems (GPS) data in Google Earth Google Earth can import GPS data in two ways: through a direct connection to your handheld GPS device, or through a GPS file, such as a .gpx file, downloaded to your computer by other third-party software like GPS Babel (www.gpsbabel.org). This tutorial will guide you how to add GPS data to Google Earth using both of these methods. In this tutorial, we will import a GPS .gpx file of elephant tracks. The data has been contributed by Save the Elephants (savetheelephants.org). Let's get started! 1. Open Google Earth. 2. If you have data stored on your Garmin or Magellan handheld GPS device, connect your device to your computer using your USB or Serial port connector, and turn on the device. This will be the data you use for the next section. 3. You will also want some GPS data with which to experiment later in the tutorial. Find the sample dataset GPS_track_Save-the-Elephants.gpx to your computer. These data have been shared by Save the Elephants, and are for use for this tutorial. Import GPS data from your handheld GPS device If you do not have a GPS unit with data on it to use during this tutorial, just read over this section briefly before skipping to the next section. 1. Make sure that your Garmin or Magellan handheld GPS device is connected to your computer using your USB or Serial port connector, and that your GPS device is turned on. Note: If you are using a USB connection, you may need to first install a driver for your GPS device. Drivers can be found on the CD that came with your device, or downloaded from the device manufacturer's web site. 2. Go to the Tools menu and select GPS. © 2010 Google 32
3. In the GPS Import window, go to the Historical tab and choose your device: Garmin or Magellan. 4. Check the boxes if you want to import Waypoints, Tracks, and/or Routes. 5. Click Import. Your data will be downloaded from your device directly into Google Earth, where you can view and save it as described below. 6. Data imported from a GPS handheld device can be animated because it has time stamps (date and time) of when it was collected by the GPS device. Simply select the GPS data in the Places panel, and click Play on the Time Controls. 7. Save your GPS data to a KML file by right-clicking on your GPS data folder in the Places panel, and selecting Save Place As... or select the GPS device data in the Places panel, go to the File menu, and select Save Place As... © 2010 Google 33
Tips: • You can also get data from your GPS device in real time. For example, if you go out in the field with your laptop, you can view your current location live on Google Earth. From the GPS Import dialog box, select the Real Time tab to see options for viewing live data. You'll need to make sure that your GPS device is connected and streaming data using one of the supported protocols (NMEA is the most common). • Before you disconnect your laptop from the internet and go out in the field, be sure to use Google Earth to fly to and view the places you'll be visiting so that the relevant imagery is saved in the cache on your hard drive. Import GPS data from a file If you have GPS data stored in a GPX or other type of file, you can open it in Google Earth. Also, if you have a GPS device for which Google Earth does not support direct connections, but which can export data to a file, you can still view your GPS data in Google Earth. Read the instructions that came with your GPS device for exporting data from your device to a file on your computer. You can also use third-party software like GPS Babel (www.gpsbabel.org) to download the GPX file to your computer. 1. If you do not have your own file to use (supported file formats are .gpx, .loc, and .mps), you can download and use this sample file provided by Save the Elephants: GPS_track_Save-the-Elephants.gpx 2. Go to the File menu, select Open... 3. In the Open window, change the filetype to the GPS file types by using the Files of type list and selecting Gps (*.gpx, *.loc, *.mps). 4. Navigate to the appropriate location on your computer and select the GPS file. 5. Click Open to begin the import process. 6. In the GPS Data Import dialog box that appears, choose to download Waypoints, Tracks, and Routes. Also, choose to Draw lines for tracks and routes, and to Adjust altitudes to ground height. © 2010 Google 34
7. Click OK. The file is imported and can be viewed in Google Earth as described below. Once you've loaded your GPS data into Google Earth, you can edit the waypoint placemarks and track paths, and add more information about the waypoints and tracks in the balloons. Tip: • You can also import a .gpx file from your computer by simply dragging and dropping it into Google Earth. © 2010 Google 35
View and save your GPS data 1. Once you have loaded your GPS data into Google Earth, you can edit the waypoint placemarks and track paths, and add more information about the waypoints and tracks in the balloons. To edit a feature in Google Earth, right-click on the feature in the 3D viewer or the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). 2. Data imported from a GPS handheld device can be animated because it has time stamps (date and time) of when it was collected by the GPS device. Simply select (highlight) the folder of GPS data in the Places panel, and click Play on the Time Controls. 3. To save your GPS data to a KML file on your hard drive, right-click (Ctrl-click on a Mac) on your GPS data folder in the Places panel, and select Save Place As. The image below shows a final product of Save the Elephant's GPS track of an elephant they monitor. © 2010 Google 36
Importing Geographic Information Systems (GIS) data in Google Earth If you have Geographic Information Systems (GIS) data, you can import it into Google Earth Pro so it can be used as part of your Google Earth visualizations. If you have Google Earth Pro, you can import many kinds of GIS data directly using the methods described in this tutorial. If you are using the free version of Google Earth, there are other tools for converting GIS data to KML, a few of which are listed at the end of this tutorial. In order for Google Earth Pro to import your data and place it in the correct location on the Earth, all GIS data must have the correct coordinate system (WGS 84) defined. For example, ESRI shapefiles must have a projection file (.prj) associated with them and GeoTIFFs must have a Tiff World File (.tfw) associated with them. This tutorial will guide you through how to import GIS data into Google Earth Pro so it can be used as part of your Google Earth visualizations. We will import a shapefile of rivers and a GeoTIFF of land cover in Southeast Asia. The rivers dataset was created from data downloaded from the Digital Chart of the World (www.maproom.psu.edu/dcw/). The land cover dataset was created from data downloaded from the Global Land Cover Characteristics (GLCC) database (http://edc2.usgs.gov/glcc/glcc.php). For this tutorial, you will need Google Earth Pro installed on your computer. If you are a non-profit organization, you may qualify for a free license of Google Earth Pro! See eligibility requirements and apply for a software grant here: http://earth.google.com/outreach/grants.html. If you are not a non-profit or do not qualify, you may buy it or download a 7-day free trial here. Let's get started! 1. Open Google Earth Pro. 2. Find the Rivers_in_SEAsia_shapefile shapefile files and LandCover_in_SEAsia_grid TIF files in your data folder on your computer. Import a GIS shapefile, or other vector dataset 1. Select Import... from the File menu. 2. Select your data’s file type from the Files of type menu. For this example, choose ESRI Shape (*.shp) from the Files of type menu, select Rivers_in_Southeast_Asia.shp, and click Open. © 2010 Google 37
If you have MapInfo .tab data, choose MapInfo (*.tab) from the Files of type menu, select your TAB file and click Open. 3. A message will appear, stating that the file contains more than 2500 features and could cause application performance degradation. When you see this message, you can choose to import just a sample, restrict to your current view, or import all. 4. Click the Import all button. © 2010 Google 38
5. A message will appear, asking if you would like to create a Style Template. Click Yes. In the next Style Template Settings dialog box, you will create a style template for the rivers, which will include colors, labels, and icons. 6. Under the Name tab, choose the field in the shapefile that you would like to use for the name labels for the data in Google Earth. You can use the preview table to view which field contains the content you would like to use for the labels. For this example, select “NAM” in the drop-down menu. This is the field in the shapefile that contains the names of the rivers. 7. Under the Color tab, select to Use single color, and click on the color swatch to the right. This causes the color settings to appear. 8. In the Select Color dialog box, choose a color for the river dataset. For this example, select a blue color, and click OK. © 2010 Google 39

Your GIS data now appears in Google Earth. Notice how the KML data is also listed in the Places panel under Temporary Places. To save it in Google Earth, click-and-drag this file to My Places. © 2010 Google 41
Import GeoTIFF, or other raster dataset 1. To import a raster data, select Import… from the File menu. Select the appropriate file format from the Files of type at the bottom, select the file you want to import, and click Open. For this example, select GeoTIFF (*.tif), select the LandCover_SEAsia.tif file, and click Open. 2. In the New Image Overlay dialog box that appears, give a name to your raster overlay, and click OK. © 2010 Google 42
Because the raster dataset in georeferenced to a coordinate system, it is automatically placed in the appropriate location. The land cover GeoTIFF has been imported into Google Earth and is located in the Places panel. In addition to importing GIS data into Google Earth Pro, you can also use many other tools and software programs to convert GIS data to KML files for use in Google Earth. GIS software, like ESRI ArcGIS and MapInfo, have tools to export GIS data into KML format for use in Google Earth. • Shp2Kml, a free utility that converts shapefiles to KML: http://www.zonums.com/shp2kml.html • ESRI ArcGIS contains tools in the ArcToolbox (3D Analyst > Conversion > To KML) for converting vector and raster GIS data to KML. • Export to KML Utility is a free toolbar extension for ArcGIS. • Arc2Earth is an extension for ArcGIS that converts GIS data to KML: http://www.arc2earth.com/ • MapInfo Professional has a MapInfo Professional Google Earth Link Utility. • MapWindow GIS has Shape2Earth, a tool for converting GIS data to KML: http://shape2earth.com/ © 2010 Google 43
Using Views and Perspectives in Google Earth You can set unique camera angles (perspectives) of your placemarks in Google Earth, by using "Snapshot View." You can control how users view your placemarks when they double-click on them or when you're recording a narrated tour of your Google Earth layer. This tutorial will guide you through how to set the camera angle, or perspective by using "Snapshot View." Let's get started! 1. Open Google Earth. 2. Open geo_example_jgi_without_views.kmz from the data folder you downloaded in Google Earth. For this exercise, make the Terrain layer visible. Go to the Layer Panel, and scroll to the bottom. Check the box next to Terrain to make it visible. Create Snapshot Views 1. Notice how there is no unique camera angle, or perspective, set for the placemarks -- when you double-click on a placemark, the Earth doesn't tilt or rotate to a unique perspective. 2. Use the mouse or the navigation tools to orient the Earth to a unique perspective for a placemark. For example, zoom into the placemark labeled "Flirt", and tilt and rotate the Earth to a unique perspective. © 2010 Google 44
3. Right-click on the "Flirt" placemark in the Places panel, and select Snapshot View. This will save your unique camera angle, or perspective, for this placemark. Using Snapshot Views can be very effective for telling stories and guiding users through your Google Earth layer in a controlled manner, helping them get the unique perspectives you want them to see. 4. You can also set the Snapshot View in the Properties window. To open the Properties, right-click on the placemark in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). Go to the View tab, and click the Snapshot Current View button. © 2010 Google 45
Now, when you double-click on that placemark in the 3D viewer or in the Places panel, Google Earth will fly to that saved view. 5. You can also assign a Snapshot View to a folder. To do this, right-click on the folder in the Places planel, and choose Snapshot View. Similar to when you double-click on a placemark, double-clicking on the folder will fly to that saved view. © 2010 Google 46
Creating a Narrated Tour in Google Earth Google Earth 5.0 and above gives you the ability to tell your story in a more compelling way, taking users on a narrated tour through your map. As the guide, you can provide a voiceover, show pop-up balloons along the way, and fly users around the globe, creating a video-like experience. Since the tour is within Google Earth, users can pause at any time, explore the planet on their own, and pick up the tour again later. This tutorial will guide you through how to create a tour using the new KML Touring tools available in Google Earth 5.0 and above. In this exercise, we will create a tour of a Google Earth project using data from Jane Gooddall Institute's Chimpanzee Blog. Let's get started! 1. Open Google Earth. 2. Open geo_example_jgi_with_views.kmz from the data folder you downloaded in Google Earth. 3. For this exercise, make the Terrain layer visible. Go to the Layers panel, and scroll to the bottom. Check the box next to Terrain to make it visible. 4. Now, let's record a tour! Create a KML Tour 1. Click the Add Tour button in the toolbar, or go to the Add menu, and select Tour. The tour recording tools appear in the lower-left corner of the 3D viewer: 2. Click the Record button to start recording actions and movements in Google Earth. The button changes to red and the time counter begins counting up, showing the duration of your current KML Tour. © 2010 Google 47
3. Create your tour by flying, zooming, panning, and rotating the globe. Do what you would do if you were showing your Google Earth project to a user or audience in person. A 3D Space Navigator, like the one created by 3D Connexion (www.3dconnexion.com), can be extremely helpful for navigating smoothly across the globe. 4. Double-click on placemarks in the Places panel to move to their unique camera angle or view. In this example, double-click on the placemark 'Flirt', then 'Patti', and so on. You can also pop placemark balloons and turn on and off your placemarks, paths and polygons in the Places panel. 5. When you are finished creating your tour, stop recording by clicking the Record button again. Your recording stops, and the Tour Player appears in the bottom-left corner of the 3D viewer. The KML Tour that you just created automatically begins playing. © 2010 Google 48
6. To save your KML Tour, click the Save to File button in the Tour Player, and give your KML Tour a name. It is then stored in the Places panel. © 2010 Google 49
7. To save it to a permanent .kmz file, right-click the tour in your Places panel, choose Save Places As…, and save your .kmz file to a location on your computer. If you used content in your tour (clicked on placemarks, popped balloons, etc), you must put those along with the tour into a single folder, and save that entire folder as a KMZ; otherwise, they will have the tour only, and no content. Re-record a tour to add new actions Want to add more actions to your tour? You can modify and extend a previous tour by re-recording a new tour while playing back the original tour. 1. Make sure your original tour is in the Places panel. 2. Click on the Add Tour button in the toolbar to add a tour. The tour recording tools appear at the lower left. 3. Click the Record button to start capturing a new tour. After clicking the record button, the time counter starts advancing, showing the duration of your new tour. 4. Now start your original tour by double-clicking on it in the Places panel, or select it with the mouse and click the Play Tour button underneath the Places panel. You are now recording a new tour while playing back the original one. 5. You can pause the original tour, add some new actions or camera movements, and then un-pause/play the original tour to continue. Note: if you move the earth during the pause of the original tour, when you hit play on the original tour the camera will jump to the where the original tour left off. © 2010 Google 50
6. Once the original tour is done playing back, since you are still recording a new tour, you can continue to add new actions or even start playing back another tour! Recording Narration 1. When creating a new tour, if you click the microphone button instead of the record button, recording will start and Google Earth will start capturing audio from your computer's microphone, as well as movements and actions in the 3D viewer. You can also turn on/off audio recording by clicking the microphone button again. Audio recorded through your microphone is captured as an .mp3 file that is saved with the tour when you save it as a KMZ file. 2. Make sure when saving a Tour with audio narration to set the 'Save as Type' option in the Save window to KMZ, otherwise the audio will not be included in your file. Tips & Tricks for Touring • When adding an iteration to an existing tour, you can click and hold on a location on the globe (i.e. building, mountaintop, etc.), and the camera will stay on that location, swiveling around it. When you un- click from that location, the previously recorded tour will continue as before. • Navigation through time is captured in the tour, so if you drag the time slider while recording a tour, any actions that cause changes in the 3D viewer (appearing/disappearing points, animations, etc) will be recorded. For example, if you have Historical Imagery turned on (link), or have a time-animated KML in My Places, try recording a tour and also manipulating the time slider (in the upper left of the 3D map view). This allows you to make tours of time-animated layers, like the Declan Butler Avian Flu map, and also showing historic imagery from different time periods. • KML Touring allows for more advanced actions than can be recorded by the simple Add Tour feature in Google Earth. This includes dynamically moving placemarks, lines and 3D models, adding pauses to the tour, and changing the styles of your features during the tour. However, you will need to hand-edit the KML to create these actions. Please see the Touring in KML documentation on the KML documentation site for more information. © 2010 Google 51
