Cultural Resources Geographic Information System (CRGIS) is a map-based inventory of the historic and archaeological sites and surveys stored in the files of the Pennsylvania State Historic Preservation Office (SHPO).

The Pennsylvania Historical and Museum Commission (PHMC) has been collecting information concerning archaeological sites and historic resources for the greater part of a century. Currently there are approximately 25,300 archaeological sites and 136,000 historic properties in these files. Access to these paper records is free and open to the public by appointment at the SHPO office in Harrisburg. CRGIS is a means of accessing some of these data without a trip to Harrisburg.

CRGIS is a partnership between the Pennsylvania Historical & Museum Commission (PHMC) and PennDOT, with financial support from the Federal Highway Administration, the Baltimore District of the Army Corp of Engineers, and the Pennsylvania Department of Environmental Protection.
