The GIS Department has now created an Open Data Site for the free distribution of GIS Data. This site allows you to search for layers by key words or by themes.
You can download the data in Excel spreadsheet format, or via ArcGIS Shapefile format. You can also filter the selection prior to downloading the data. Additionally, we have links to our public facing Mapping websites and story boards.

This is a connection to the Dauphin County GIS Data Portal.
The following categories are available:
Boundaries
Election
Hydrology
Tax Assessment
Transportation
Elevation

The following Applications are available:
Mobile Parcel Viewer - provides the general public and other interested parties access to searchable and interactive information such as property tax and assessment information or the locations of water access points.

MDJ (Magisterial District Judges) Locator - Identifies Magisterial District Judge and Municipality

Dauphin County Homicides - Application showing Dauphin County homicides in 2015 and 2016

Parcel Viewer - Search for a Parcel, Property Information, Tax Assessment, Municipality, Assessed Land or Building Value, Acres, etc.

Digital Data is distributed as a countywide dataset in ESRI shapefile format. Aerial imagery is available as a countywide dataset either through Dauphin County GIS or downloaded from PA Spatial Data Access (PASDA also available on the Commonwealth Open Data portal)

As part of our ongoing commitment to promote transparency, accountability, innovation and citizen engagement, Montgomery County has designed this data site to provide information on county initiatives and as a place to access the County's official published GIS data and applications.
