Overview_Description:
Entity_and_Attribute_Overview:
A polygon coverage depicting areas classified by the
Division of Environmental Management as having either
protected or critical water supply watershed areas. The
polygon attribute table (PAT) has attribute data including
total area in coverage units (square feet), total perimeter
(linear feet), polygon internal identification number,
polygon user identification number, a DEM internal index
number that relates to the identification of the stream
which runs through the watershed, the classification of the
watershed, the river basin the watershed is contained in,
the name of the stream which runs through the watershed, the
classification date of the watershed, the DEM internal grid
number that relates to the 7.5 minute USGS topographic map,
the type of watershed -whether (P)roposed or (C)ritical, and
the number of acres per polygon. There are no look up tables,
annotation or cartosets for this data.
A deductive estimate was used to determine the attribute
accuracy value. The value domains used are as follows:
High - greater than 90% reliability;
Medium - greater than 75% reliability;
Low - less than 75% reliability.
