GIS Manager


The Geographic Information Services Department has the privilege of maintaining the County's Geographic Information System (GIS), which links databases to mapping information for use by County Departments and by the public. We also provide a variety of planning related services including long range planning, project site planning, computer graphics for presentations, planning coordination with other jurisdictions, federal project reviews, and special projects.

Special Project: Gunnison Valley School Community Atlas Project

The Gunnison Valley School's Geography class worked on a GIS/Mapping project using ESRI software that was acquired through a Gunnison County 4-H grant. Click here to view this project.
