Update frequency of dataset: Weekly

Last Update Date: August 2023

Accuracy of attribute: Attributes are correct as per County of Chester Assessment Department

Positional accuracy of dataset:

The PARCELS layer (and derived copies PARCEL_PUBLISH and PRCL_POLY) was originally created through a conversion process of digitizing hand drawn tax maps into digital form and orientating the tax map sheets and parcels to the features depicted in the 1993 orthophotos. These parcel polygon features were adjusted based on aerial photography dated April 7, 1993, and road centerlines, right-of-way lines and other physical features generated from the same photography. While the imagery has a pixel resolution of 1.5 square feet, a positional accuracy of +/- 5 feet and is designed for use at a scale of 1 inch = 200 feet, the resulting PARCELS horizontal accuracy varies from reasonably accurate in the best cases to less accurate in the worst cases. Subsequent and current map update processes include metes and bounds entry from subdivision and deed information, as well as property corner locations based on GPS points and the utilization of our newest imagery datasets. While the update processes include more accurate methods, the resultant overall accuracy is still dependent on the surrounding parcel fabric's varied accuracy. Planimetric coordinates are based on the Pennsylvania State Plane Coordinate System South Zone and North American Datum 1983

Note: There is a difference between land use code and zoning. Land management occurs via a land use designation which determines the land use code. This designation specifies how land and resources within it is managed. Zoning designations define how a property can be developed and used and it is controlled by each township/borough. See below for list of codes.
