Abstract :
Multi-beam RADARSAT-1 satellite imagery has been used as part of a terrain mapping program in Alberta, Canada. Principal components analysis (PCA) has been applied to standard beam modes with incidence angles of 20-27° (S1) and 45-49° (S7) for both ascending and descending passes. The results provide imagery that characterize geomorphology, geologic structure, vegetation differences and a measure of moisture content. These features are highlighted through the interaction of incidence angles and look directions.
