Cities, Towns, Villages with 1990 Census Population (GNIS)
Metadata from the RGIS Metadata Repository
Identification Information
- Title Cities, Towns, Villages with 1990 Census Population (GNIS)
- Date 2009-03-30
- Date Type Publication
- Cited Responsible Party
-
- Organization Name Earth Data Analysis Center
- Role identify
- Presentation Form vector digital data
- 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.

- Logical Consistency Report Point features present. The coordinates from which the points were derived were
determined manually from paper 7.5 minute map sheets. The points are only as accurate as
the original manual locating process allows.
- Completeness Report 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.

- Process Step
-
- Process Description 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.
