Technical Abstract: ABSTRACT The USDA Agricultural Research Service and Natural Resource Conservation Service are cooperating to evaluate the impact of conservation practices on water quality and quantity at the watershed scale. This requires accurate and timely information regarding land use practices within watersheds under investigation. Current methods of land use mapping are limited by data availability and dynamic changes in cropping, field boundaries and forested areas. This is especially so in the Southeastern U.S. A primary goal of our research is to evaluate new methods of rapid land use assessment using high resolution aerial and satellite remote sensing. Bimonthly ASTER satellite data and monthly aerial images are being acquired for 2005 over the 334 km2 Little River Experimental Watershed located in south-central Georgia. The watershed is subdivided with stream gage and precipitation stations at each of seven sub-watersheds ranging in size from 3 ' 155 km2. Coincident with remotely sensed data acquisition detailed field survey data are catalogued and will be used to validate derived land use maps. Preliminary results from satellite and airborne data acquisitions will be presented.
