1. A system comprising: a first array of cameras, each of which has a first focal length and is disposed to image a respective portion of a wide area scene, the first array of cameras providing a first spatially continuous view of the wide area scene; and a second array of cameras operably coupled to the first array of cameras, each of which has a second focal length different from the first focal length and is disposed to image a respective portion of the wide area scene, the second array of cameras providing a second spatially continuous view of the wide area scene, wherein at least a portion of the first spatially continuous view of the wide area scene overlaps with the second spatially continuous view of the wide area scene, wherein the first array of cameras and the second array of cameras, taken together, are configured to provide a first image of a first target at a first distance in the wide area scene and to provide a second image of a second target at a second distance, different from the first distance, in the wide area, wherein the first image and the second image are at a substantially constant resolution, wherein the substantially constant resolution is about 1.5 centimeters or less.
