Landform Delineation
Landforms often have characteristic shapes which may be manifested as
topographic relief. The ability to image landforms is a result of the
side-looking configuration of radar, which highlights relief.
RADARSAT beam mode - All beam modes are suitable for landform
delineation. The final beam mode selection is dependent on the areal coverage
and level of detail required. Generally, Fine and Standard beam modes are best
suited for detailed landform delineation, while Wide and ScanSAR are better
for regional landform delineation.
RADARSAT incidence angle - Shallow incidence angles are ideal for
enhancing subtle terrain features, through shadowing.
Look direction - Orientation of land forms relative to look direction
should be considered.
When to acquire RADARSAT data - Acquire data when landform
information is required, regardless of season. Avoid periods of heavy
snowcover.
