The Remote Sensing and Geographic Information Group of the U.S. Bureau of Reclamation's Technical Services Center has mapped irrigated lands within the Upper Colorado River basin using satellite imagery. All imagery was collected during the summer of 1995 and was processed over the next several months. Surface reflectance data were collected on the ground as well as by plane and will be used for radiometric correction. Process images to derive information regarding soil brightness, green vegetation, and moisture conditions Develop irrigated vs. non-irrigated decision thresholds Ancillary data including hydrography, soils information and topography will be incorporated to assist with image interpretation and analysis. Work for the initial phase of the project was completed in May 1996.
Subsequent work is ongoing.
