Geographic Information Systems
GIS is a Wapello County Department that administers and maintains the county geodatabases, including parcel (property) data (derived from surveys, data from Assessor, Auditor and Recorder’s offices, & CAD files from the Secondary Roads Department). This data is then utilized to create the Wapello County online map, and is also used for reporting, spatial analysis, calculating & deriving new statistics.

If you are looking for a plat map of a property, you may visit our online map at:

If you have questions or are having problems with accessing the online maps you may stop by the GIS or Assessor’s offices located on the first floor or the Wapello County Courthouse in Ottumwa.
