Rosemary Mosher, who works with the Geographic Information Center (GIS), will present this wonderful program that will begin with the earliest history of Windham using early maps, particularly the map of 1871. Through her GIS work, Rosemary is able to isolate homes, stores, schools, cemeteries, and other notable town locations and she will show aerial “now and then” comparisons of various areas of town. This program is quite remarkable and we guarantee it will intrigue you.
