RBV

Domain	Definition
Geological	The RBV system on Landsats 1 and 2 consisted of three television-like cameras aimed to view the same 185 km-by-185 km area as the multispectral scanner (MSS) sensor. The RBV system did not contain film. The images were exposed by a shutter device and stored on a photosensitive surface within each camera. This surface is then scanned in raster form by an internal electron beam to produce a video signal. The RBV system instantaneously imaged an entire scene, had greater inherent cartographic fidelity than imagery acquired by the Landsat MSS sensor, and contained a reseau grid in the image to facilitate geometric correction of the imagery. This resulted in an array of tick marks that were precisely placed in each image. The RBV system on Landsat 1 produced only 1690 scenes between July 23 and August 5, 1972, when a tape recording switching problem forced a system shutdown. The RBV system on Landsat 2 was operated primarily for engineering evaluation purposes and only occasional RBV imagery was obtained, primarily for cartographic uses in remote areas.These images are no longer available.
