Squint

Squint is an important angular parameter associated with the collection geometry of a SAR image. In order to align around a single definition of squint, values for this angular parameter have been modified across the Canopy application. The following diagram illustrates the new squint angle to be returned from Umbra's APIs:

Squint will be accessible for collects under squintAngleEngineeringDegrees; for Stac Items, squint will be accessible under umbra:squint_angle_engineering_degrees.

In the Canopy User Interface, squint will simply be represented as Squint, but this is referring to the same value as squintAngleEngineeringDegrees.

Canopy will also be providing additional parameters that are commonly used across the industry: squint exploitation and squint degrees off of broadside.
