Geographic Information Systems
GIS Services was formed in 1997 for the purpose of creating a Geographic Information System capable of efficiently and effectively meeting the organization's geographic information needs.
The GIS Division is also responsible for administering the Pictometry/Eagleview program. The Eagleview program provides aerial imagery and oblique imagery which is aerial imagery captured at an angle, providing a more natural perspective and making objects easier to recognize and interpret. With imagery captured from four simultaneous directions, we can produce a 360-degree view of every property and parcel in the county. This imagery easily integrates into the County’s GIS data for a comprehensive understanding of properties, land features, local topography, and more.
The GIS departmental goals are to coordinate the human, capital, and fiscal resources to build the major base map layers critical to the county agencies. The numerous project benefits include eliminating data redundancy and duplicate effort, increasing accuracy and currency, and improving access and availability of geographic information.
The department is responsible for updating existing map data and coordinating application development. In consideration of the scope of the project, the provision of mapping and data services to citizens, other government agencies, and the business community is limited and based upon resource availability.
The spatial and graphical information contained in the County's GIS is designed and maintained to satisfy the needs and requirements of County offices.
The County is willing to freely share this data with any other government agency within Grand County. Grand County cannot make commitments to further develop the GIS data for the interest of outside government agencies, nor can Grand County commit to reproducing maps, reports, or copies of this data on behalf of those government agencies that have received this data.
Changing Physical (SITUS) Address:
The process to change a physical (situs) address for a property is to submit a written or email request to either the GIS or Assessor’s Office, preferably from the owner of the property. Government or emergency service agencies may verbally request a change, in which case the property owner will be notified by mail at the mailing address we have on file.
