This website is the result of years of cooperation between the various offices and departments in Jasper County. In the early 1990's, Jasper County started maintaining its cadastral maps on the computer. Jasper County contracted with the Sidwell Company from St. Charles IL to obtain aerial photography of the county and produce CAD drawings of their plat maps. In 2000, Jasper County took the next step and obtained more aerial photography of the county only this time, the aerials were delivered in computer files, not paper as it was delivered in 1991. The CAD maps were then converted to work with the new digital aerial photosso they may be served on the web, which happened in 2004.Staff from the various offices work together to maintain this system. Information from the Assessment and the Tax Administration Systems have been incorporated with this mapping component to enhance its value. Offices throughout the county government use this data and maps daily. Workstations in the Assessor's office and Auditor's Plat Room may be used by the public to access this information.
