The Supervisor of Assessments office has embraced a new technology now being used by many levels of government to aid in maintaining tax parcels, boundaries, soil types etc.
The above picture is an example of parcel boundary lines over our aerial maps which were flown in the spring of 2004. This view can be used to help land owners visually identify and discuss their properties building structures, land uses etc.
The picture shown below is that of our aerial photography (2004) with USDA soils overlay over it.
By using these GIS maps in our office we are able to maintain updated soil maps as well as parcel boundary information.
Due to mandated changes in how farmland is calculated using individual soil productivity index' (PI'S) vs. weighted soil PI'S the previously published crop yield estimates (circular 1156) were more than 22 years old. Changes in crop yields and rotation have had a wide impact. Now using Bulletin 810 each soil type has new crop yields, this maintains accuracy and incorporates the effects of improved technology on crop production and soil productivity.
The internet mapping site that is being developed will allow the general public as well as realtors and appraisers to create maps and search public information. The maps will be for viewing only and are not available for download at the present time. Please refer to and review the following disclaimer:
