Lineament Identification
Lineaments, such as folds and faults may be manifested as topographic relief.
The ability to image lineaments is a result of the side-looking configuration of
radar which highlights relief.
RADARSAT beam mode - The beam mode chosen is dependent on the
area coverage and level of detail required. Generally, Fine and Standard beam
modes are best suited for detailed lineament identification, while Wide and
ScanSAR are better for regional identification.
RADARSAT incidence angle - Steep incidence angles are ideal for
enhancing the subtle topographic relief of lineaments.
Look direction - A look direction perpendicular to direction of lineaments
enhances their detectability. The acquisition of both ascending and descending
passes maximizes the number of lineaments that can be identified.
When to acquire RADARSAT data - Acquire data when lineament information
is required.
