MDNET is a point coverage that represents the locations and names
of a network of observation wells for the State of Maryland. Additional
information on water conditions at these sites can be found in the
Ground-Water Site Inventory System (GWSI) database, which is maintained
by the U.S. Geological Survey. Site information can be accessed on the
internet at URL: <http://water.usgs.gov/nwis/>
The dataset MDNET was created to provide locations of Maryland ground-water
observation wells 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.
