As part of GEOG-426 GIS I, I utilized ArcMap to georectify a series of Sanborn Fire Insurance maps of the City of Spokane from 1890, then combined the georectified maps with data downloaded from Spokane Open GIS to create a series of maps showing different aspects of the city in 1890. While the exercise was done to show knowledge of georectification it also had the benefit of teaching a was a historian might use of GIS.
