HYDROLOGIC FEATURES - LINE ATTRIBUTES

Following is a summary of the line (arc) attributes which are
present in the ArcView coverage H_100K. They may be selected using attribute
LTFREQ and the corresponding number, or by the attribute LINETYPE and
the corresponding character string. FREQUENCY lists the number of
occurences for each attribute in this line coverage.

This map was created by linking 7 USGS 1:100,000 scale DLG files and
eliminating all boundary lines (DLG files: ze1.hyf05,ze1.hyf06,ze3.hyf01,
ze3.hyf02,ze3.hyf05,ze3.hyf06,rh4.hyf04,rh4.hyf08). USGS major and minor
attribute codes present in this map coverage are also summarized
below. Major code 50 is HYDROLOGIC FEATURES. These codes may also be
used to select, or isolate, particular features.

Arcs without data, and empty attribute columns, are labeled major and
minor code -99999.
