EurekaDownload Eureka2.zip ... This sample covers an area of about 22,000 square kilometers in eastern California and southwestern Nevada, including the area of the Big Pine simulation near the southwest corner. Like that simulation, the texture layer is a Landsat 7 RGBI image from 2 July 1999 that uses the 15-meter panchromatic band 8 to sharpen a 30-meter natural color image (bands 3-2-1). Although this texture covers about 80% of a full Landsat scene at a ground resolution of 18 meters, the dataset size is a modest 45 MB because the texture is stored as linked JPEG2000 image files using lossy compression. (The uncompressed file size would be 180 MB.) The area stretches from the Sierra Nevada mountain crest and Owens Valley in the southwest, across the White-Inyo Mountains, to the basin-and-range topography of western Nevada (northeast half of the scene). Eureka Valley lies just southwest of the center of the scene, and northern Death Valley is in the southeast corner. This is a rugged desert landscape with many salt-encrusted dry lake basins (playas), which appear as bright white patches. Green irrigated fields can be seen in parts of the Owens and Fish Lake valleys in the western half of the scene.
