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...
The Dam Removal Information Portal (DRIP) is an online representation and visualization tool for the USGS Dam Removal Science Database, inspired by Bellmore et al. 2015 and now developed as a live data system in ScienceBase as part of the Biogeographic Information System. DRIP provides a map-based visualization of information of dam removals and associated scientific studies. The database was developed in cooperation with the NGO, American Rivers, who also provides data on other dam removals that lack associated scientific studies. The original software for the online DRIP application was developed in cooperation with AppGeo. Basic information about the dam’s location, size, date built and date removed are provided...
