GIS Evolution
Beginnings of GIS for City of Cheyenne
The City of Cheyenne’s digital mapping process began in 1985 from a customized mapping and modeling program. This program was recommended by the Mayor’s Drainage Task Force and was approved for funding by the City’s Governing Body. The system was developed and maintained by the City Engineer’s Office.

In 1990 the City Engineer, Planning, and Cheyenne Area Metropolitan Planning Organization (MPO) Offices began research into a Geographic Information System (GIS). At this time the Cheyenne MPO purchased ATLAS GIS from Strategic Mapping and this was used for 2 years by the City.

Needs Analysis & Funding Expanded System
In 1992, the Cheyenne MPO conducted a County-wide GIS Needs Analysis which provided the guidelines to expand the GIS system. ARC/INFO software, developed by Environmental Systems Research Institute (ESRI) was selected. Funding for the expansion of the system was provided largely by the City of Cheyenne and the Cheyenne Area Transportation Planning Process, (ChATPP, the Cheyenne Area MPO). At this time other City and Laramie County Departments joined into the cooperative GIS which expanded the system to a multi-agency/multi-jurisdictional program.

Since the GIS Program in the Cheyenne area developed from the ground up, those involved have benefited from the sharing of data and resources. Technical support between departments has grown to become one of our most valuable assets.

Joint Program Adopted
In 1998 a second GIS Needs Assessment was completed to re-establish conceptual designs, implementation plans and strategies. In July, 1998 the City of Cheyenne and Laramie County jointly adopted, by resolution, the CHEYENNE/LARAMIE COUNTY COOPERATIVE GIS PROGRAM. This formal action will assure the continuation of the cooperative commitment to the GIS in the City of Cheyenne and Laramie County for years to come.
