This data release contains a series of tabular crosswalks with spatial weighting for facilitating the conversion of spatial data between different hydrographic networks and spatial units. The child items in this repository contain the following types of intersections: polygon to polygon polygon to raster flowline to polygon flowline to flowline The format of these files is zipped csv contain three columns: id_source: the identifier of the polygons requiring weights. id_target: the identifer of the polygons of the target data to be intersected with the id_source weight (w): the fractional overlap of id_source to id_target Additional details for each of these can be found in the metadata underneath each child...

The National Water-Well Database (NWWDB) is a compilation of water-well records from state-managed databases that have been standardized to a common format for consistency across state and administrative boundaries. Water-well completion reports that are submitted to permitting state agencies by licensed drillers constitute a large source of hydrogeologic information, including the locations and distribution of water wells, construction materials and completion depths, lithologic logs, groundwater levels, and the results of pumping or aquifer tests. Standardization was performed based on a U.S. Geological Survey (USGS) profile of the Open Geospatial Consortium (OGC) GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html)....
