Color Ortho Imagery Released for Download
Also Viewable In All KYGEONET Internet Mapping Sites!
Full color aerial images of the commonwealth are now available for download and viewing on the Kentucky Geography Network (KYGEONET). The aerial photos of Kentucky were taken in late summer of 2004 by the National Aerial Inventory Program (NAIP) on behalf of the United States Department of Agriculture (USDA), Farm Service Administration (FSA). The product of their flights were “leaf on” ortho-rectified images suitable for use in Geographic Information Systems (GIS), Computer Aided Drafting (CAD) software and in a variety of other applications.
The images were projected and transformed into the standard Kentucky Single Zone Coordinate System by Kimberly Anness of COT's Division of Geographic Information and were processed and tiled for database loading and download by Bryan Bunch, Kentucky Environment and Public Protection Cabinet. Their work was performed in just a few short weeks, thus making the data available to the commonwealth’s GIS, consulting and engineering communities in the shortest possible time.
The imagery is the latest “snapshot” of the commonwealth and replaces the grayscale imagery obtained during the 1992-2001 time period. Both the new and the old datasets are considered 1-meter pixels (1 meter on the ground equals one pixel on the computer screen) but the full color imagery with its “leaf on” view allows the user to see and resolve many more features.
The primary reason for obtaining the data was for agricultural and forestry related applications, thus the “leaf on” (all the trees have leaves because it is summer) status captures information regarding crops, their rotations and other items of interest. However, for some applications the “leaf on” status is a drawback because the tree cover obscures the view of roads and other features in the commonwealth’s more wooded areas.
The commonwealth obtained the imagery through a partnership with USDA. The United States Geological Survey (USGS) also contributed to Kentucky’s portion of the matching funding.
