Geographic Information Systems

Geographic information systems (GIS) are designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.

The GIS Department develops and modifies the geographic database, performs spatial analysis, produces maps and assigns emergency 9-1-1 street addresses for Johnson County.

These maps and databases can be used for anything from viewing information regarding a particular address such as the 9-1-1 address and what Precinct or Voting Precinct it is located in to mapping out a disaster area to aid first responders and other crucial entities to aid the public.


Please see 911 Addressing to apply for an address within Johnson County.

Visit Interactive Maps to view and access non-sensitive data for public use.
