Description: This line coverage contains arc features representing all photogrammetricallyinterpreted street centerlines in the county, including roads built during or after1993. RPT will resolve and generate road names.
Description: Hydrography Centerlines. This dataset contains lines representing all perennial streams and the centerlines of rivers wider than 10 feet. The features are pointed in the direction of streamflow. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features.
Description: This line coverage contains arc features representing photogrammetrically interpreted Rail Road centerlines. County Planning Commission supplied reference map to identify active features from abandoned features.
Description: Arcs representing photogrammetrically interpreted surfaces and edges of public and private roads. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features.
Description: Polygons representing photogrammetrically interpreted surfaces and edges of public and private roads. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features.
Description: This polygon coverage includes both recent and historical cemeteries. County supplied source data to identify historical locations. Dataset consists of all cemeteries which were identifiable in the 1993 photography, plus historical cemeteries which were mapped using other source data and or verification methods.
Description: Polygons within this coverage represent the outlines of each covered bridge in Lancaster County, PA, as determined via aerial photographs.
Description: Polygons representing photogrammetrically interpreted edges of paved and unpaved drives greater than 200 ft. in length. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features.
Description: This dataset contains polygons representing all perennial streams, rivers, ponds, lakes and other bodies of water wider than 10 feet. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features.
Description: This polygon coverage represents photogrammetrically interpreted surfaces and edges of parking lots. All lots in excess of 1000 square feet will be compiled. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features.

Description: This a county-wide coverage that contains polygons showing the urban and village growth boundaries in the county. Growth boundaries are split along municipal boundaries.
Description: 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 boudaries 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.
Description: Current buildings feature class used by Lancaster County. This dataset consists of polygons representing footprints for any building that is approximately 100 square feet or greater.
Description: Polygon layer representing public parks, public and semi-public recreation land and other conservation land and easements. Based on the tax parcel layer and aerial photographs.
