San Joaquin ValleyDownload CV2.sim ...
This Landscape File covers part of the eastern side of the San Joaquin Valley in central California, USA. It includes two stacked terrain surfaces. The more extensive terrain depicts the surface of pre-Cenozoic crystalline basement, and its single texture layer is a color shaded-relief depiction of that surface. Crystalline basement is widely exposed at the ground surface in the Sierra Nevada mountains in the eastern third of the area, but is buried by younger sedimentary strata below the valley surface. The second terrain represents the ground surface of the San Joaquin Valley and lower Sierra foothills. The texture associated with the ground surface is a composite color image created from three bands of a Landsat Thematic Mapper satellite image. In this image vegetation appears green, water bodies dark blue, and bare rock and soil are expressed in shades of gray, magenta, and purple. A mask was used in preparing this texture to limit the image area to the valley surface where the basement rock is buried below the sediment fill.
