Planimetric Coverage containing the delineation of impervious surfaces for studying and calculating drainage runoff. This coverage shows surface features that are visible on the aerial photography, and is sometimes referred to as the landbase.

Polygon coverage representing the predominant land use or land cover, as interpreted from aerial photography. Note: GDI delineated the land use boundaries using aerial photographs dated March 1993 and using a minimum mapping unit of one-half acre. Based on acquired aerial photography, subsequent updates have been made in: 1998, 2002, 2005, 2008 and 2012. ADR compiled land use polygons for all surface water features. NWI wetlands areas were identified using boundaries from a Quad-based wetland coverage; the wetland boundaries were then delineated using the aerial photography. Land uses are categorized using the Modified Anderson Level II classification system. Quality control check plots were produced at 1"=250' scale the whole county. Planning Commission staff reviewed all of the check plots and forwarded comments and corrections to GDI. GDI made some of the corrections but did not make others, claiming that they were below the half-acre minimum mapping unit limit. Planning Commission staff has also made corrections where they have been found.

This data represents the railroad centerlines for Chester County. Only active rails and rails that are in place, but do not have current service are represented in this data layer. Rail lines that have been abandoned are represented in the historic rail data layer. The railroad centerlines were originally based on aerial photographs taken April 7, 1993. Updates to the layer have been made based on additional research and aerial photograph taken in spring 2000.

Boundary polygons of public water systems (PWS) service areas for community water systems (CWS). The locations were digitized from maps submitted with Annual Water Supply Report for 2000, 2001, 2002 and 2003. Maps not included in these reports were requested by mail on June 12, 2003, June 25, 2004 and December 30, 2005. Revisions, updates and additions are made on an as needed basis. All boundaries should be considered approximate.

Bridges in Chester County -- this dataset is primarily derived from PennDOT's Bridge Management System (BMS). Full attribution from BMS is available for state-owned bridges greater than 8 feet in length and locally-owned bridges greater than 20 feet in length. Additional bridges are added for planning purposes, such as bridges listed on a state Bridge Bill or within the Chester County Planning Commission's Transportation Improvement Inventory.
