GIS for Union and Snyder Counties

 New Image

The GIS Department maintains a computer system and a database of digital mapping covering Union and Snyder counties. We assign 911 addresses and maintain digital parcel layers.  Our data and maps are used for dispatching 911 calls and to assist with tax assessment. We also develop maps and build new user applications to support the use of GIS by all of our county agencies and municipalities. Project work includes collecting, editing and maintaining digital data, watershed modeling, environmental constraints analysis, and municipal planning applications.

Our GIS contains data layers such as parcels, municipal boundaries, topography, land-use, watersheds, roads, bridges and buildings.

Data and maps are pushed out to be shared via the web through several web maps, story maps and editable feature layers.



"In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e. data identified according to their locations. Practitioners also regard the total GIS as including operating personnel and the data that go into the system."
