USGS Quads (1:24000) Theme added

KGIS has created another map theme within its KNOXnetWhere mapping site specifically for display of the United States Geological Survey (USGS) 1:24000 scale topographic maps (also known as the 7.5-minute quadrangles). Within the theme, users will be able to display current-day KGIS features (such as parcel boundaries) on top of the USGS quads, which continue to be a great cartographic reference even though they have not been updated since the early 1990s, when the USGS 1:24000 program ended. For access to other historic USGS maps covering other areas of East Tennessee,  visit the Univ. of Tennessee Map Library's Online Topographic Resource.
