Abstract:
This data set contains points for 1600 populated places, cities,

and towns in New Mexico. The points were generated from latitude

and longitude coordinates contained in the GNIS file, and therefore,

do not have a known scale.

Purpose:
This data set was created to show the locations of towns in New Mexico

mainly as a reference background to other geographic features.

Supplemental_Information:
Procedures_Used:

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.
