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 nnnnnnNnnnnnnnW. 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 geographic 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.
