GIS and CAMA

Integrating GIS and Computer Assisted Mass Appraisal (CAMA) enables the tax assessment function of government to be concurrent with spatial data that is relevant to the tax valuation model. It also supports the creation and maintenance of a more accurate land records basemap using the tools and functions of GIS (e.g., topology checking, map projections and adjustments, map editing tools) and provides a single repository of parcel geometry and descriptive data supporting work flow, updates, and mass appraisal input.

GIS adds value to CAMA models, such as an appraisal model, which can place added value on property that has, for example, frontage on a golf course or lake. If the parcel data and land use data are maintained in a geodatabase, the frontage calculation is simple and easy using the spatial intelligence of the GIS.
