Abstract |
Remotely-sensed aerial photography of two small strip-mined East Tennessee watersheds was used as a means for obtaining land-use information essential to econometric and hydrologic studies and for reclamation practice surveillance. 1:12,000 scale maps were produced for both watersheds from three color IR photographic flights. Other available high altitude photography and thermal imagery data data were used to help map strip-mine disturbed areas. Excellent photographic coverage and quality permitted approximately 5,041 acres of watershed, representing 847 acres of disturbed bench, slope, and slide areas to be mapped for each mission at a cost of less than 10 cents/acre. The study demonstrated the usefulness of using low altitude IR photography for identifying, mapping, and measuring strip-mine disturbance areas. (Modified author abstract) |
