GIS Data

Data Information

Lancaster County data sets originated and are maintained by the IT/GIS, PlanningProperty Assessment, and Lancaster County-Wide Communications departments of Lancaster County. The county distributes both vector and raster data sets to the public. Vector layers are generally provided in ESRI shapefile or DXF file formats. Raster data sets are provided in geospatially referenced TIFF or JPG formats.

Data layers were created from aerial photography (scale varies depending on layer). These data are intended for use at a 1:2,400 or smaller scale and conform to National Mapping Accuracy Standards of planimetric and topographic mapping data at a design scale of 1 inch equals 200 feet.

Notice - Parcel Viewer Data and Third Party Applications

The GIS Data on the Parcel Viewer CD no longer works with the Parcel Locator GIS application developed for the Lancaster County Association of Realtors. Parcel Locator was not developed by the county and is no longer supported by the developer.  Based on the status of Parcel Locator, we will not be able to provide Parcel Viewer data in a format that supports Parcel Locator. Parcel Viewer does, however, include a GIS data viewing application which can be used to view and query the data on that CD.
