and longitude coordinates contained in the GNIS file, and therefore,
do not have a known scale.
mainly as a reference background to other geographic features.
A completed dBASE III file of New Mexico place names was obtained from
the local GNIS contractor. Coordinates for longitude and latitude were
extracted from that file. They are in the format nnnnnnNnnnnnnW. A C program
was written to remove the N and W; insert spaces between the degrees, minutes,
and seconds as well as between the 2 coordinates; and reverse the order so that
longitude was first. Next, points were created in ARC/INFO 7.0.3 with the
generate command. Then the point file was joined back to the GNIS file attributes.
From the GNIS Web Site a text file of population, elevation, and 7.5 minute
topographic quad map name was obtained. Using the GNIS ID, This new data was
attached to the point data set.
Revisions:
This data set has been revised once to correct points for which the original
coordinates were incorrect.
Reviews_Applied_to_Data:
Points were checked for accurate locations by drawing them against a background
of county boundaries and comparing county names of the two files for matching.
