Andrew LaMotte 20010705 Maryland Water-Use Data, 1998 Version 1.3, July 06, 2001 ARC/INFO coverage USGS Open-File Report USGS OFR 01-247 Baltimore, Maryland U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?mdwu_98 MDWU98 is a point coverage that represents the locations of wells for the State of Maryland that are permitted to withdraw 10,000 gallons or more per day by the Maryland Department of the Environment (MDE). Each site has the permit number, permit amount, reported withdrawal, aquifer code, and type of use. Information contained in the dataset comes from the U.S.Geological Survey site-specific water-use database (SWUDS). The dataset MDWU98 was created to provide the locations of MDE permitted ground-water withdrawal sites in Maryland for use within a Geographic Information System. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ARC/INFO format, this metadata file may include some ARC/INFO-specific terminology. 1998 Current as of 10-14-99 Complete Static dataset -79.40368872 -75.12260266 39.7417308 37.99119635 none Water-use Well Ground-water Withdrawal inlandWaters none Maryland none Data should not be used at scales greater than 1:24,000.
