Sidwell Chosen to Provide GIS Data Enhancement Services for Williamson Central Appraisal District

Under the most recent agreement, Sidwell will conflate the cadastral line feature class of the existing GIS.  Feature tags will be assigned so that, when queried, the selection set can be used to create topologically accurate polygons.  Sidwell will also register all cadastral boundary features in the GIS to the current digital orthophotography. According to Pamela Orr, WCAD’s Director of Operations, “Williamson Central Appraisal District chose The Sidwell Company for this GIS parcel rectification project due to their highly qualified and professional staff.” Orr adds, “Based on our prior experience with Sidwell, we appreciated getting a project that not only came in on time and under budget, but provided excellent customer service.”
 
Sidwell was previously selected by WCAD to convert their cadastral parcels from a MicroStation DGN format into the ESRI Geodatabase format, in addition to implementing their industry-acclaimed, ArcGIS®-compliant Parcel Builder™ software as a map maintenance solution.  This project, along with the Sidwell-developed public-access website which features the WCAD map data, and tabular data, was completed in late 2008.
