Abstract
ArcMap Tool for USGS NWISWeb Track: Water Resources Author(s): Steven Predmore The U.S. Geological Survey national water database (NWIS) contains a wealth of groundwater, surface water, and water quality datasets that are available to the public on the national Web site (NWISWeb). However, querying data from the NWISWeb is difficult when using geographic information systems such as ArcMap. To simplify this task, an ArcMap tool was developed to query and download data from the NWISWeb for a selected map extent. Data is downloaded for the included sites and a temporary shapefile is created. The shapefile is displayed on the map with a hot link that connects to the NWISWeb "Site Description" page for each site. This tool also allows the user to select a site and explore groundwater, surface water, and/or water quality data related to the site through the hot link to NWISWeb. This data can then be downloaded in a tabular format to use in ArcMap.
