Compare this scene, centered on the Wind River Basin, with this Landsat 1 MSS scene that includes, and extends beyond, the mosaic. When examined full size on a light table,this black and white scene shows more ground detail, even in that tonal mode, than does the Landsat full image but the even-toned nature of the latter compensates somewhat for the information quality. The mosaic here has several of the problems inherent to aerial products. The amount of sidelap was minimal, so the pictures could not be trimmed. The inherent average gray levels darken from the central area of each picture, such that the boundaries between photos are emphasized.
Exact joins are difficult owing to edge distortions.
This gives the mosaic an overall blocky or patchwork appearance that detracts somewhat from its presentation of the feature content.
