AbstractIn preparation for RADARSAT, scheduled to be launched in 1995, the Canada Centre for Remote Sensing (CCRS) has acquired airborne C-HH band data on several Canadian and international sites to demonstrate the utility of SAR for geological mapping, mineral exploration and geological hazard studies. ERS-1 and JERS-1 data are also available on some of these sites. One objective of these investigations is to generate enhanced and integrated SAR images, which would facilitate geological interpretations. This summary paper presents guidelines of some of the more geologically useful SAR enhancements and integration techniques and discusses their applications in two geologically different areas of Canada. The enhanced and integrated SAR images were used for structural and lithologic mapping. The techniques used include (a) the enhancement of SAR texture and tone by filtering and contrast stretching; (b) the creation of SAR perspective views; (c) integration of SAR with geophysical, geochemistry, TM and multifrequency data using arithmetic combinations and IHS techniques.
