What’s New in

Topographic

Information - USGS National Map

+ 2USGS

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.

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

What is NHDPlus?

An integrated suite of application-ready geospatial data sets developed to enable estimates of flow volume and velocity to support pollutant fate-and-transport (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
