Sanborn maps can be used to locate specific properties and document the development of towns, large and small. The workshop will include hands-on exercises in using Walker Library’s subscription to Digital Sanborn Maps (black & white) in Tennessee and the Sanborn map digital collections (in color) at the Library of Congress and the University of Tennessee Libraries.
The USGS Historical Topographic Map Explorer (http://historicalmaps.arcgis.com/usgs/) provides access to more than 178,000 maps dating from 1884 to 2006. Hands-on exercises will cover site navigation and how to use the transparency tool to view both the historical map and the current landscape. The session will also include a brief demo of using the georeferenced images in web mapping applications (e.g., ArcGIS Online).
