Vector polygon map data of property parcels from Montgomery County, Pennsylvania containing 307,283 features.

​

Property parcel GIS map data consists of detailed information about individual land parcels, including their boundaries, ownership details, and geographic coordinates.

​

Property parcel data can be used to analyze and visualize land-related information for purposes such as real estate assessment, urban planning, or environmental management.

​

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

This annotation map service shows tax parcel dimensions for Montgomery County, Pennsylvania.

An elevation or topographic contour is a line that connects a series of points of equal elevation and is used to illustrate topography, or relief, on a map. It shows the height of ground above Mean Sea Level (M.S.L.). Numerous contour lines that are close together indicate hilly or mountainous terrain; when far apart, they represent a gentler slope. This layer consists of contours at a five foot interval for Montgomery County. Data was derived from DVRPC and was generated from an aerial topographic survey in 2005.The Delaware Valley Regional Planning Commission's (DVRPC) 9-county region is made up of the following: Bucks, Chester, Delaware, Montgomery, and Philadelphia counties in Pennsylvania; and Burlington, Camden, Gloucester, and Mercer counties in New Jersey.The regional dataset can be be accessed via rest service or downloaded from PASDA

This layers shows major watershed boundaries in Montgomery County, Pennsylvania. This USGS map layer displays the National Watershed Boundary Dataset (WBD) for HUC12 boundaries.The intent of defining hydrologic units (HU) for the WBD is to establish a base-line drainage boundary framework, accounting for all land and surface areas. The WBD is a comprehensive aggregated collection of HU data consistent with the national criteria for delineation and resolution. Each HU is identified by a unique hydrologic unit code (HUC).

This layer shows the approximate location of sewer lines in Montgomery County, Pennsylvania. Data was created using various past data sources which cannot be fully determined. The most recent update to this data was 2018.

This index corresponds to the coverage of DVRPC's PA State Plane (South Zone) orthoimagery in the 5-county, Pennsylvania portion of the DVRPC region.Each polygon is attributed with the source of the 2015 imagery for that particular tile; either Quantum Spatial, US Army Corps of Engineers (USACE) and AXIS Geospatial, or a combination thereof.

This index represents the coverage of the scans of DVRPC's non-orthorectified, mylar, aerial photo enlargements.. These polygons were developed to define the overall extent of the imagery, and to assist users in locating the particular images of interest to them.This layer includes a "STATUS" attribute field that indicates what scans are missing, however this is not a complete inventory of missing scans.Prior to the year 2000, DVRPC’s aerial imagery consisted of mylar aerial photo enlargements or “atlas sheets”. These atlas sheets were produced from 9x9" aerial photos. The imagery dates from the years 1959, 1965, 1970, 1975, 1980, 1985, 1990, & 1995. The 1959s and 1965s primarily cover the urbanized portion of the DVRPC region (the DVRPC region is made up of nine counties: Bucks, Chester, Delaware, Montgomery, and Philadelphia in Pennsylvania; Burlington, Camden, Gloucester, and Mercer in New Jersey). Subsequent years provide full coverage of the region, minus the occasional missing scan.In order to increase the efficiency of using the historical aerial imagery, the sheets were scanned into TIFF (Tagged Image File Format) files. Each TIFF file ranges between 35-40MB in size. Unlike DVRPC’s more recent aerial imagery (2000 and later), the historical aerials are not “orthorectified” or “orthocorrected”. In other words, they are simply aerial images with no spatial reference or uniform scale. Through the process of georeferencing, the scanned images can be assigned a spatial reference which will enable them to be used more readily in a GIS environment. That said, georeferencing is not orthorectifying or orthocorrecting. What it does allow is for the scan to be displayed relative to other spatially referenced GIS layers. A georeferenced scan does not have the properties of an actual orthoimage. Whereas an orthoimage can be used for making accurate measurements, a georeferenced image cannot, as it does not have the spatial accuracy and uniform scale of an orthoimage.
