AbstractA study involving the application of remote sensing technology for geological mapping in arctic environments has been initiated in southern Baffin Island. Various remotely sensed imagery, characterized by different wavelengths and spatial and spectral resolutions, have been or is presently being acquired. This area has been chosen as it represents a typical arctic geological and biophysical environment. It has a variety of lithologies ranging from gneissic and/or granitoid basement rocks to rift-related volcanic and sedimentary rocks to younger overlying Paleozoic sediments, and has been mapped on a regional scale (1:100 000) by the Geological Survey of Canada.Particularly relevant for this project is the recent advancement of hyperspectral remote-sensing technology. Eleven lines of high-resolution hyperspectral data have been acquired using the Noranda Probe sensor over the study area. Preliminary results indicate that the optical sensors (Landsat TMand Probe) provide useful information with respect to compositional layering, structural patterns, and vegetation.
