+ What s New in Topographic Information - USGS National Map SARGIS Workshop November 14, 2016 Rob Dollison, 703-648-5724 rdollison@usgs.gov
+ USGS 2 National Geospatial Program The National Geospatial Program provides a foundation of digital geospatial data representing the topography, natural landscape, and built environment of the United States. These data and derived products and services can be accessed through The National Map Data Download and Visualization Services.
+ 3 Topics Major Program Efforts Topographic Information: USGS Products Launch Page and Data Download Client What s coming
+ 4 Area of National Leadership Program Emphasis A-16 Lead for Terrestrial Elevation 3D Elevation Program (3DEP) A-16 Co-Lead for Inland Waters (Hydrography) National Hydrography Dataset (NHD) Watershed Boundaries Dataset (WBD) National Coverage of Topographic Maps U.S. Topo and Alaska Mapping
+ 5 3D Elevation Program (3DEP) Applies ground-breaking lidar technology to acquire and distribute 3D data Includes surface elevations and natural and constructed features Increases the quality level of lidar being acquired to enable more accurate understanding, modeling, and prediction Addresses a broad range of critical applications of national significance
+ 6 + 6 Light Detection and Ranging
+ 7 3DEP Data Quality Improves and Enables Applications 10 meter resolution 1 meter resolution
+ 9 3D Elevation Program (3DEP) Mission Critical Applications Aviation Safety Flood Risk Management Geologic Hazards Infrastructure Management Precision Forestry Alternative Energy Archaeology
+ 10 National Hydrography and Watershed Boundaries Datasets (NHD and WBD) Surface water layers of The National Map The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and stream gages The WBD represents drainage basins at 8 scales of a nested hierarchy and defines the areal extent of surface water drainage to a point, accounting for all land and surface areas Together, a powerful database Contains a flow network that allows for modeling and tracing water downstream or upstream Uses an addressing system based on reach codes and linear referencing to link information such as water discharge rates, water quality, and fish population National Hydrography Dataset Watershed Boundaries Dataset
+ 11 What is NHDPlus? NHD WBD Elevation An integrated suite of application-ready geospatial data sets developed to enable estimates of flow volume and velocity to support pollutant fate-andtransport (dilution) modeling Incorporates many of the best features of the National Hydrography Dataset (NHD) Watershed Boundary Dataset (WBD) 3DEP - National 1 Arc-Second Seamless DEM Includes - NHD names (GNIS) and networking Value-added attributes (VAA s) Stream and catchment attributes Elevation-derived catchments for each stream segment Flow direction and accumulation grids
