Home > What We Do > Mapping > Parcel Data Conversion

Changing land development and increasing property values make it important for a community to maintain accurate parcel maps to identify and maintain the currency of legal boundaries for public and private properties. Sanborn Parcel Mapping products deliver detailed, accurate digital resources that commercial and public users can use to determine important parcel data. Sanborn parcel data conversion products provides location, size, shape, and parcel identification number for specific properties. This allows for easy identification of where a specific property is located relative to adjacent properties and public roadways. This is important information for planners, assessors, developers, and engineers with regard to compliance with local zoning regulations, modification and / or expansion of utility infrastructure, as well as for tax assessment and appraisal purposes.

Parcel data is derived from existing maps (scans or hard copies) and legal information by geospatially registering imagery using a heads-up digitizing technique. Parcels also can be collected by employing COGO methods to enter the legal metes and bounds. These parcel mapping processes are used to create a new parcel base map or update an existing base map for AutoCAD or ESRI environments. Existing parcels may need to be topologically “cleaned” to eliminate slivers and gaps between parcels, and orthoimagery also may be used for greater accuracy in location of parcel lines. The final product may be delivered as a parcel fabric, simple shape file, or DWG depending on the needs of the user and their existing single-user or enterprise GIS systems.

Leveraging an expert team of GIS, Survey, and Project Management professionals employing leading-edge hardware and software techniques, Sanborn has completed parcel data conversion projects to satisfy varying specific customer requirements for communities across the United States. Our successfully executed projects range in scope from maps created through cleaning and updating existing datasets, to developing custom parcel base maps from newly acquired data.
