Abstract | The radar sensor onboard RADARSAT is the most sophisticated civilian equipment of its kind in orbit. The many beams, with variable incidence angles, and the variety of acquisition modes give RADARSAT
an unparalleled degree of flexibility. The value of these features is beginning to be appreciated, and they are particularly useful to geologists because they provide cloud-free images in which illumination can be controlled and enhancement of
terrain morphology maximized at resolutions ranging from 8 to 50 m and for surface areas of 2,500 to 250,000 km2.
The Sudbury region in Ontario is one of the most important base metal mining camps in Canada. Because of the
knowledge available on the geology, geochemistry, geophysics and morphology of the surrounding area, Sudbury is one of the most important test sites used by the Canada Centre for Remote Sensing (CCRS) to evaluate RADARSAT data. A concurrent study
has been initiated in the region surrounding the Geraldton mining camp, which is the location of a greenstone belt containing several gold and base metal indicators.
A wide range of RADARSAT beams and modes have been used in both these regions
to obtain a better understanding of image characteristics and the differences between images, and thereby to provide advice to geologists. |
