The HydroLink App is no longer supported. We recommend exploring the Hydrography Addressing Tool or related Python Hydrolink methods to meet your hydrolink needs. The HydroLink Tool aids in generating a linear reference for point data to the NHDPlusV2.1 Medium Resolution and NHD High Resolution hydrography layers. The tool employs the researcher’s local, field-based knowledge of the geospatial features where data were collected to improve both the spatial accuracy of the research data and assist in the linkage to these national surface water datasets. Once the point location data are verified and linear referencing is complete, the output dataset includes the verified latitude and longitude coordinates and additional...
As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover.
The TNM Download Tool provides comprehensive access to all of the available stored maps (GeoPDF format) and downloadable data from The National Map.
