Frequently-anticipated questions:


What does this data set describe?

Title: 1947_index_extents
Abstract:
Extent of 1947 georeferenced aerial photographs. Photographs were georeferenced in ArcGIS using the georeferecing toolbar. Control points for each photo's georeferencing were saved as text files. Photos were aligned with 2005 NAIP imagery and 1938 imagery. The quality of each image varies as some photos were underexposed/overexposed and off-nadir.
