[This is an encore presentation recorded in April. We'll be back with a new episode Thursday.]

John Baeten came to town as a visiting assistant professor in IU’s geography department, where he spent time doing, among other things, a reconstruction of maps of Bloomington from the past. That led to his current post as the GIS Coordinator for Monroe County. GIS stands for Geographic Information Systems, of which there are many at the county. In fact, it’s hard for any local government to do their jobs these days without some kind of GIS capacity.

Baeten talks with us about all sorts of interesting projects on the county’s state-award-winning GIS website, like stitching together aerial images of the county taken in the middle of the 20th century, a project mapping racial covenants in real estate deeds across the county. mapping the prevalence of radon, even mapping ticks for the health department.
