The hydro springs feature service is a hosted feature service that covers the continental United States, Alaska, Hawaii and Puerto Rico. It is designed to be used for offline field use as a reference. The data is delivered through the Forest Service Enterprise Data Warehouse (EDW). Data is refreshed semi-annually April and November by the EDW and the Geospatial Technology and Applications Center (GTAC) in Salt Lake City. Data consists of Forest Service authoritative data, and authoritative data from other government agencies. In addition to filling mapping needs the map is designed to help support data management and national data efforts. The Hydro Springs feature class is a subset of springs extracted from the Springs Stewardship Institute Springs Online database ( http://springsdata.org ), exported from Springs Online. Each record in the feature class has a unique SiteID assigned by the online database. This feature class is related to the primary table, tbl_Surveys, in a one to many relationship. Related tables are not present in this feature service.
