Geographic Information System (GIS)

What is GIS?

“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.”

“A geographic information system (GIS) is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps.”

“GIS is an integrated system of computer hardware, software, and trained personnel linking topographic, demographic, utility, facility, image and other resource data that is geographically referenced.”


About Us

Worcester County’s GIS is currently housed in the Department of Comprehensive Planning. The GIS began as a regional effort in May 1997 between the Worcester County Commissioners, Assateague Island National Seashore, Maryland Coastal Bays Program and Maryland Department of Natural Resources to support the activities of the regional GIS. In November 2004, Worcester County decided fulltime GIS support was needed to meet the growing demand of GIS in the county system. Today, GIS supports a wide variety of government functions including emergency services, water and sewer projects, comprehensive planning, watershed planning, development review proposals, public works projects, and more.
