The Auditor's GIS database was designed to allow for maximum versatility and growth as additional information becomes available in digital form.
Layering Concept used Franklin County Auditor's Geographic Information System
To allow for easy access, storage and manipulation of vast amounts of data, a "layering" concept was implemented as described below.
For example, a paved driveway would be classified in the following manner: Subject - planimetric feature, data layer - secondary transportation, data item - paved drives, which could then be accessed in the computer under the reference number of 09072.
The data layers and data items contained in the GIS Manual represent a logical and efficient layout of the planimetric, topographic and appraisal databases. To date, the Auditor's office has compiled more than 60 layers of appraisal related information. The current design of the system will allow for acquisition of 512 layers with a possible 255 items in each layer.
