Geographic Information System Division

The GIS Division of the Community & Economic Development department develops and maintains Doña Ana County's Geographic Information System (GIS). The Division maintains over one hundred layers of information (databases), develops department-specific applications, produces maps, and provides training and technical support to other County departments.

All of the Division's digital data are available to the public for nominal reprographic fees. Some of the data available include street centerlines and names, ETZ zoning, County zoning, and corporate boundaries. County maps are also available for a nominal reprographic fee. (Please note that this does not include the parcel base, which is available from the County Assessor's Office.)

The GIS Division also administers the Road/Street Naming and Addressing Ordinances which includes assigning physical addresses in the unincorporated portions of Doña Ana County. The Ordinances are currently being revised, and will be available online in the future.
