Chester County incorporates the use of Geographic Information Systems (GIS) in several departments and agencies that use geographic data in their key business functions. GIS integrates maps and databases through computer technology.
The GIS team is responsible for providing land record support to several county departments, as well as to taxpayers and real estate professionals. GIS staff verifies information from deeds and plans when new parcels from subdivisions are recorded in the County.
Subdivision plans that have four or more lots are GPS’d (Global Positioning System). The data is collected and verified so parcel lines can be accurately depicted on the County’s Cadastral Parcel layer.
The GIS team also maintains the road center line mapping layer. These edits support the Chester County Department of Emergency Services. Other dispatch-related mapping layers such as response zones, fire stations and hydrants are also maintained.
GIS staff are responsible for maintaining the physical location (situs) address data in the address tables of the Bureau of Land Records database. This information is provided by the County’s 73 municipalities and is for 9-1-1 dispatching purposes. It is also used by Enterprise GIS users for geocoding and map display via layers such as Parcel Publish.
The GIS team maintains several enterprise GIS layers, including:
These layers are updated daily and used in applications such as ChescoViews and ChescoPIN.
