Improved image quality has direct significance to the many mineral and petroleum exploration organisations that are now routinely applying conventional photogeological interpretation techniques to Landsat multispectral scanner imagery. Photogeological techniques will continue to be the main means of Landsat interpretation, however, even the best quality imagery may contain less than one quarter of the total data recorded and computer techniques offer the only adequate means of analysing all the data in a Landsat scene. Considerable progress has been made with computer analysis of Landsat digital data and some techniques have definite application to mineral and petroleum exploration. In specific environments direct detection of iron weathering products associated with both hydrothermal alteration and uranium deposits has been achieved. Various computer-enhancement techniques have also been employed to reveal structural and lithological information not obvious on conventional Landsat imagery or aerial photography.
