Geographic technology allows us to view landscapes in unique and insightful ways. This photograph combines a satellite
image with a digital elevation model to show the relationship of urban areas (in gray shades) and topography near Los
Angeles, California. Of particular interest is the nearby location of the San Andreas Fault, which is the linear feature that
angles from the upper center of the image to the lower right.
