As part of this year’s OSU GIS Day events on November 15th, we are organizing a Columbus Sanborn map Georef-a-thon. We are crowdsourcing an effort to georeference historical Sanborn fire atlas maps for Columbus to support CURA’s Ghost Neighborhoods project and a national effort to understand the persistent impacts of redlining on US cities.
Bonus – you can literally see past come alive as you georeference!
Many thanks to OSU Libraries for supporting this effort.
