Overview
The Estuary Data Mapper (EDM) is a free, stand-alone tool for geospatial data discovery, visualization, and data download for estuaries and their associated watersheds in the conterminous United States. Using a variety of federal agency web services, EDM provides ready access to environmental time series data such as water and sediment quality, freshwater discharge, and tides. Users can select specific datasets for display and download or choose pre-packaged options designed to provide input to specific decision support tools and models. Outputs are available in open-source formats, including shapefiles, kml files, and ASCII grids.
