    About Us

    Pima County Geographic Information Systems (Pima County GIS) converts and maintains geographic data in ArcGIS, AutoCAD and other computer program formats. A primary use for this data is to assist Public Works departments in automating and streamlining their operations. Pima County GIS also provides programs and assistance to users who wish to access their data directly, including training in the use of GIS software, hardware, and related concepts.

    Pima County GIS also focuses on the production of meaningful end-products. These may be cartographic maps and displays or reports derived from simple or complex data analysis processes. The division provides assistance in retrieving useful data from the Pima County GIS Library.

    GIS data and services are supplied to Pima County departments, other public agencies, and private commercial users in exchange for fees. All users benefit by sharing the cost of developing expensive GIS databases and applications. Non-commercial users have access to the county's GIS data for the cost of reproduction.
