Abstract
Multi-beam RADARSAT-1 imagery, composed of varying incidence angles and look directions, have been used to study the surficial geology and landforms in the Churchill Tectonic Province of Canada’s north (1:250,000 NTS map sheet 66A) and northern Baffin Island (1:250,000 NTS map sheet 37G). Principal component analysis was applied to the orthorectified and Gaussian filtered multi-beam data. Each component image highlights different elements of the terrain (surficial and vegetational) as a function of different imaging geometries. By combining various principal component images into a colour ternary image, separation of various surficial units can be obtained. In addition, classification of the component images and raw images produces terrain maps that highlight features of the landforms, surficial geology and vegetation types. Validation of the classification is based on surficial geological mapping (1:125 000 scale), LANDSAT TM, and digital elevation model integrated into a Geographical Information System.
