  • History of the GIS


    The City of Grand Junction began work on the GIS project in 1991. The project’s coverage area was established at the city limits as of July 1990 with an area of 14.9 square miles. The project’s coverage area is currently defined as the 201 sewer service boundary with a 65.4 square mile area. The boundary has been squared off to quarter section lines to facilitate the exchange of data with Mesa County's GIS. Currently the GIS team is staffed with six full-time positions.

    GIS data is accessed by the public and staff through the GIS web site established in 1999, which consists of five custom maps with three hundred and eighty two unique layers. The team also maintains the paper city map and provides additional paper map services to city departments, for example the map books that Police, Fire, and Utilities use in the field.

    The GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, reports, and charts. Multiple map layers have basic database information attached to them and can be viewed queried by themselves or in conjunction with other layers.

    A Geographic Information System (GIS) integrates maps and databases to capture, store, manage, analyze, and display all forms of geographically referenced information. GIS has evolved from a long tradition of map making. In many respects a modern GIS dramatically increases the amount of information that can be contained and manipulated in a map.

    A GIS helps us answer questions and solve problems by looking at data in a way that is quickly understood and easily shared. The uses of GIS are limited primarily by our own imagination.
