Geobotanical determination of aggregate source material using Airborne Thematic Mapper imageryThe possible use of vegetation to discriminate parent materials for suitability as aggregate source material is examined. Airborne Thematic Mapper data of two test sites representing potential alluvial and residual source areas in central California were analyzed. It is found that the most useful images were composites that included principal components bands and a Perpendicular Vegetation Index band. The image processing demarcated species compositional differences which characterized a shale site and revealed differences in an alluvial site caused by moisture stress due to aggregate size and sorting.
