Department of the Interior Priorities (slide 1 of 4)
Foundational data and science underpin DOI and Administration priorities
◼ Conservation - multiuse land management, wildlife and habitat management, wetlands
inventory and mapping, water resource management, and coastal zone management, biological
carbon stocks assessment

“The US Global Change Research Program identified
Landsat as a critical observatory for climate and
environmental change research due to the unbroken length
of the Landsat record and its ability to monitor remote
regions with surface features such as glaciers, rainforests,
permafrost, and coral reefs.”

Department of the Interior Priorities (slide 2 of 4)
Foundational data and science underpin DOI and Administration priorities
Infrastructure
◼ 3DEP, NHD, and geophysical data are
foundational and directly applicable to a broad
range of infrastructure applications
◼ Data acquired have a high ROI for infrastructure
as well as a broad range of other applications
◼ Data are acquired by the private sector, creating
jobs
◼ Data programs are “shovel ready”
◼ The Federal and industry capacity exist to
execute and deliver
◼ Data acquisition is easily accounted for and
auditable
◼ No new O&M tail is required
◼ We have shown success before with ARRA – a
proven process

improve mapping across these data
■ Including engineered hydrologic systems
■ In particular, storm water systems in midsized
to larger cities
■ Need more research into the "Goldilocks"
level of storm system mapping+ 64
National Hydrography Infrastructure
■ While there is an abundance of water-related data
collected, the Nation lacks a systematic way to
organize, search, and discover it
■ NHI will provide a data infrastructure for federated
sharing and discovering of water information in the
context of the stream network
■ Includes tools to reference data to the stream
network, and to search and discover the data of
others
■ Search and discover tools are available as Web
APIs that can be implemented as portals to find ▪ Sharing and integrating water data that
information on specific topics of interest are used to inform decision-making and
improve outcomes for sustainability
▪ NHI can provide a data infrastructure
engine for the Internet of Water+ 65
3DHP Data Acquisition
■ Specifications
■ Specs for updating the stream network using
elevation data released in July 2020
■ Hydrologic unit and hydroenforced DEM
specifications in the future
■ All 3DHP will have to meet spec
■ Work to create a 3DHP BAA process
underway
■ Partnership coordination
■ Project with NSGIC to coordinate with states
■ Federal partnership coordination through
NHI Working Group

Next Steps
◼ Complete and publish the 3DNTM Call for Action:
3D Hydrography Program
◼ Educate and build support with partners and
users, including through the NSGIC hydrography
project
◼ Continue pilot projects deriving hydrography
features from elevation and perform other critical
research
◼ Continue to build out prototypes of the NHI tools
and APIs
◼ Develop an acquisition plan, including a BAA, for
acquiring hydrography derived from elevation+ THANK YOU! 67
