Sub-sampled Degree 0R digital picture of the Earth that may be considered on a scene basis to rapidly assess normal floor space protection, information high quality, and the spatial relationships between floor area coverage and cloud coverage. A browse image offers a coarse spatial resolution image with a lowered data volume to facilitate screening of the archived Landsat 7 knowledge.
