About GIS

GIS stands for Geographic Information System which is a combination of computer hardware, software and geographic data which can be used to perform data capturing, analysis, cartographic map display and production. Yavapai County Government uses GIS technology throughout several departments including the Assessor’s office, Elections, Development Services, Public Works and Flood Control among others, comprising nearly 200 users.

The GIS started in late 1992 with the primary goal of creating a digital land database of all parcels in the county. The initial project addressed the issues of planimetric data acquisition, aerial flights of the county, and initial conversion of county assessor’s maps to a digital format. To see a history of GIS within Yavapai County, view the Yavapai County GIS StoryMap.

Yavapai County land mass covers 8,127 square miles with only about 25% of the land is privately owned. The rest is publicly owned including Bureau of Land Management, Department of Interior, US Bureau of Indian Affairs, national forest, national park service, State Parks, and State of Arizona trust. Elevations range from 1500 ft to 7979 ft where the County is divided by the mountain into two areas, an eastern area called the Verde Valley; a western area including Prescott which is the County Seat. Population of the County in 1990 was 107,714 (US Census) and in 2010 was 211,073.

Development Division

The GIS development division is responsible for the design and maintenance of the county’s GIS which is used to generate the various geospatial datasets such as parcels, roads, zoning, and district boundaries just to name a few. Additionally, we create custom applications which are used to distribute GIS data to the departments, local governments and citizens of Yavapai County. Under strong leadership and technical resources, YAVGIS provides several key services on behalf of the program. When performed centrally, these services eliminate duplication of effort and promote the development of agency-specific systems.

Typically, YAVGIS provides the following services:

  • GIS technology coordination, consulting and implementation
  • GIS application development and maintenance
  • GIS data design, automation, documentation, and distribution
  • GIS strategic planning and system integration planning
  • GIS training for county staff
  • Database administration
