Description:

Abstract:

This Wyoming Cities coverage contains data for 109 Wyoming towns, cities, and Census Designated Areas. The coverage was created from U.S. Census Bureau Tiger Data. It contains many of the same attributes as the Census Bureau .dbf files, but there are a few modifications. A code has been added to distinguish towns, cities, and CDPs. Also a Countyseat item has been added to provide a way to display the County Seats only. Latitude/Longitude coordinates were also converted from the Census Bureau format to be used in GENERATE.

Purpose:

The purpose of this data layer is to provide a way to accurately display the locations of all Wyoming cities on maps and within GIS applications.

Process_Step:

Process_Description:

At <http://www.census.gov/geo/www/tiger/resource.html>, there is a dBase file made available by the US Census Bureau that contains all lat/long coordinates for cities, towns, etc., in the United States. Once the self-extrac file is downloaded, it can be executed to obtain dBase files for each state. First, all unnecessary data was dropped (using dBase). Latitude and longitude were converted to a decimal format. The file was saved in comma- delimited text format for use in Arc/Info's GENERATE utility. Because of some extra characters in the .csv file, some modification were required. The Arc/Info command GENERATE was used to create a coverage with the lat/long locations of all Wyoming cities.

Once the coverage was generated, attributes were added. The original Wyoming dBase file (geoexwy.dbf) was used, some fields were changed and deleted. As above, latitude and longitude were converted to decimal degrees by dividing by 1,000,000. Any unwanted fields were taken out. The file was then converted into INFO format using the Arc/Info command DBASEINFO. The command joinitem was used to join the table to the coverage.

In addition to the Census Bureau fields, two fields were added, within INFO, for display purposes, CODE and COUNTYSEAT.
