Geographic Information Systems

Our Mission: The Cameron County GIS was initiated in 1998 as an effort to improve law enforcement, fire, and ambulance services to unincorporated portions of the county. In response to the ineffective rural route and box addressing system, Cameron County adopted and implemented E-911 addressing standards from NENA (National Emergency Numbering Association). The addressing system assigns numbers based on 5.28 foot intervals from a specific starting point. The GIS department is currently helping all county residents with the transition from the rural route and box address system. Constant changes to the GIS map provide emergency response services the latest changes to roads and structure data. Mapping a county of more than 1,100 sq. miles is a never ending process, partly due to the changes in road surface conditions and the increase of new construction throughout the county.

Services: Cameron County 's GIS issues E-911 addresses for most of the county's unincorporated and incorporated areas. Maintaining the E-911 database for all of Cameron County and updating PSAPs (emergency response dispatch centers) with the latest GIS map.
