The Copper Country Historical Spatial Data Infrastructure (CCHSDI) is a spatial-temporally linked historical geographic information system built on period-accurate Sanborn Fire Insurance Plans (FIPS). The CCHSDI links built, social and environmental variables across seven decades from 1880-1950, focusing on the towns of Calumet and Laurium in Michigan's Upper Peninsula. On the individual scale the CCHSDI links Polk City Directories, IPUMS full-count census data, mining company employee records, hospital records, and school records from the local public schools across space and time.
