It has been a fun change of pace to start working with mapping software again. For example, I made this simple map from EPA ecoregion data for my “Birth of the Bluegrass: Ecological Transformations in Central Kentucky to 1810″that will be in the Register next spring. My research focuses primarily on the Inner Bluegrass, the darkest polygon in the above map. I’m also planning maps to show regional hydrology, changes in county-level crop production and livestock numbers, and expanding nineteenth-century transportation networks. Any suggestions for other features to include?
