Dauphin County Zoning layer created using municipality zoning maps. Zoning codes vary by municipality, thus the organization of zoning into a unified code provides a clear structure for comparison and analysis of density and land uses.

Tax parcel information intended to be used with the Dauphin County Tax Parcels. This is a periodic extract from the Dauphin County Tax Assessment database and may not reflect the most current information on file.The information in this table includes assessed land and building values, Clean and Green (Act 319)participation status, deeded acres, property use code, parcel site address, information about all associated owners, and mailing address.Please note that the city, state, and zip code fields contained in this data are for the mailing addresses. Dauphin County Tax Assessment does not maintain city, state, and zip code information for site addresses.

Polling place locations. Locations were initially collected in 2006 using a GPS unit based on information provided by Dauphin County Elections and Voter Registration. The dataset is updated as needed using aerial imagery, streets and address point data.

This data product has a county-wide coverage and is intended to provide a useful representation of the geometry and topology of tax parcels. The maps were derived from a variety of source documents including certified survey maps, deed descriptions, subdivision plans, and condominium plats. This product is intended for graphical representation and the information contained herein should not be relied upon for determination of ownership or market value.

The voter district boundary dataset was created using boundary description prior to May 2006. The dataset is updated when boundary changes are approved by the courts.

This data product has a county-wide coverage and is intended to provide a useful representation of the geometry and topology of tax parcel dimension lines.

The Dauphin County, PA 2016 QL2 LiDAR project called for the planning, acquisition, processing and derivative products of LIDAR data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LIDAR Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83 (2011) State Plane Pennsylvania South Zone, US survey feet; NAVD1988 (Geoid 12B), US survey feet. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.4 Files formatted to 711 individual 5,000-foot x 5,000-foot tiles. Tile names use the following naming schema: "YYYYXXXXPAd" where YYYY is the first 3 characters of the tile's upper left corner Y-coordinate, XXXX - the first 4 characters of the tile's upper left corner X-coordinate, PA = Pennsylvania, and d = 'N' for North or 'S' for South. Corresponding 2.5-foot gridded hydro-flattened bare earth raster tiled DEM files and intensity image files were created using the same 5,000-foot x 5,000-foot schema. Hydro-flattened breaklines were produced in Esri file geodatabase format. Continuous 2-foot contours were produced in Esri file geodatabase format. Ground Conditions: LiDAR collection began in Spring 2016, while no snow was on the ground and rivers were at or below normal levels. In order to post process the LiDAR data to meet task order specifications, Quantum Spatial established a total of 84 control points (24 calibration control points and 60 QC checkpoints). These were used to calibrate the LIDAR to known ground locations established throughout the project area.

Land uses and land cover for use in comprehensive plans, transportation plans, growth management initiatives, and determining the potential change to land and land use from various projects.This layer is a land use and land cover layer based on "A Land Use And Land Cover Classification System For Use With Remote Sensor Data" by James R. Anderson, Ernest E. Hardy, John T. Roach and Richard E. Witmer. It covers the Tri-County region, and uses: the ID categories set forth by Lancaster County's modified Anderson level 3 land use and land cover model, completed in 1999, the existing land use layers from each county, aerial photographs (from 2012, 2013, and 2014), hydrology, and forest block layers from each county. It features a minimum land area threshold size of 3 acres. ID Modified Anderson Level II Land use code 111 through 970. Valid codes are as follows: 111 Residential - less than 2 units per acre. 112 Residential - 2.1 to 7 units per acre (villages, neighborhoods, highway strip houses). 113 Residential - more than 7 units per acre (trailer parks, apartment buildings, condominiums, row homes). 114 Farmsteads - farmhouses, usually associated with and including, barns and outbuildings. (NOT including large, commercial-sized hog/chicken operations - #230). Agricultural production may or may not be active. 120 Commercial and services - Any apparent store, shop, mall, gas station or place of business where large-scale production is not occurring. 130 Industrial - Large buildings that may have production in process. 140 Transportation and utilities - Wide transportation corridors (including 4-lane divided highways), toll booth areas, highway departments, transmission stations, water towers/tanks, sewage treatment plants. 150 Industrial and commercial complexes - Large areas where there are many adjacent industrial plants and/or other businesses. Only used when unable to determine the exact use as either 120 or 130. 160 Mixed urban or built-up land - Densely developed land generally associated with urban centers. This category is often comprised of a mix of other developed land categories (i.e. 113, 120, 150, and 180) and is generally only used where development patterns are too complex to easily delineate separate developed land categories. For this project, this category will be rarely (if ever) used because the 300-scale photos appear to be sufficiently detailed to allow discrimination of separate categories. 170 Other: Areas whose land use does not fit into any particular category or can not be interpreted from the aerial photography. 180 Institutional - Schools, hospitals, or other institutional facilities. Churches and adjoining cemeteries. Stand-alone municipal buildings, including parking/storage areas for municipal equipment (i.e. snow plows). Also, stand-alone fire houses. Usually large buildings, surrounding access road with parking areas some landscaping, well-kept grounds. 190 Recreational - Active Recreation Parks (i.e. ball fields, playgrounds, tennis courts). Also campgrounds, golf courses, hunt clubs. 211 Agriculture: cropland 212 Agriculture: pasture 213 Agriculture: other unclassified agriculture land 220 Orchards/groves/vineyards/nurseries/other horticulture,Trees/plants forming grid or regular patterns. 230 Large Confined Feeding Operations - Usually associated with a farmstead (114) these are commercial-sized buildings housing hog or chicken operations. 240 Other agriculture 310 Herbaceous - Open, grassy areas with few tress or shrubs. Generally refers to ungrazed or uncontrolled grass land, but also includes very large lawns and large cemeteries not adjacent to a church. 320 Shrub/brush - Areas where shrubs, brush, and/or very small trees are present. 330 Mixed cover - Areas that are not forested but have a mixture of vegetation. 410 Deciduous forest. 420 Coniferous forest. 430 Mixed forest. 500 Open water (Hydrology polygons from ADR). 610 Forest Wetlands. 730 Sandy non-beach. 740 Rock outcrops 750 Mines/quarries/pits and junk yards/land fills. 760 Transitional (under construction). 770 Mixed barren and vegetated (basic disturbed class). 997 Islands less than minimum mapping unit size. 998 Any land within a tile that is not in an area where mapping is required.

This feature class was compiled using several datasets that had been previously been maintained by the Dauphin County Emergency Management Agency (EMA) and referencing 2003 PAMAP aerial photography. The existing datasets were combined into a single dataset which was then updated to include all the buildings 100 sq ft or larger that were visible on the aerial imagery. The featue class is edited on a case-by-case basis, based on the collection of new building information submitted by EMA or Dauphin County IT or through examination of updated aerial imagery.
