Abstract :
A geological database comprising coregistered Landsat Thematic Mapper (TM) regional multielement stream sediment geochemistry, regional gravity and aeromagnetics, and geological map data has been established, in raster format, for the area of the English Lake District. To study spatial correlations within the database, TM imagery and its first-order structurally enhanced filter derivatives are combined with regional survey data using intensity-hue-saturation transforms and stereoscopic-view generation techniques. These are then overlaid with line and polygon information from other exploration datasets. Datasets are combined in a manner which maintains the identity of each dataset. The imagery produced demonstrates the power of image presentation for efficient multidata analysis.
