ITEM DESCRIPTION
FIPS Federal Information Processing Standard State and County Code. ELEVATION Elevation of feature in feet. LAT_ORG Latitudinal coordinate locating the approximate center of areal features. Also, latitudinal coordinate of point in coverage for linear and areal features. LONG_ORG Longitudinal coordinates locating the approximate center of areal features. Also, longitudinal coordinate of point in coverage for linear and areal features. LAT_HEAD Latitudinal coordinates locating the mouth of linear features such as streams. LONG_HEAD Longitudinal coordinates locating the mouth of linear features such as streams. COUNTY Name of county in which feature occurs. DESIG Designation of the feature. (PPL = populated place.) NAME Name assigned to the feature by the USGS. DESCRIPT FGDL added item based on NAME.
USER NOTES:
The Geographic Names Information System was developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names. Its purpose is to promote geographic feature name standardization and to serve as the Federal Government's repository of information regarding feature name spellings and applications for features in U.S. The names listed in the inventory can be published on Federal maps, charts, and in other documents. The feature locative information has been used in emergency preparedness, marketing, siteselection and analysis, genealogical and historical research, and transportation routing applications.
FGDL QUALITY ASSURANCE STATUS:
-Projected to FGDL Albers
-Tolerances were set to FGDL standards
-Set Precision to double
-Points that were obviously misplaced (i.e Gulf of Mexico) were deleted
-DESCRIPT item was added based on NAME
