Collect Geometry

The Canopy API provides a number of view geometry properties that can be used to determine the relative positions of the target on the ground with the satellite at the time of Collect.

Name	Field	Description
Azimuth Angle	Metadata: `angleAzimuthDegrees`	The Azimuth Angle is measured clockwise from north as measured from a point on the ground directly below the satellite. Not to be confused with "Target Azimuth Angle".
Grazing Angle	API: `grazingAngleDegrees` / Metadata: `angleGrazingDegrees`	The Grazing Angle is the angle between the local tangent plane at the target location and the line of sight vector between the satellite and the target. Imagine standing on the ground at the target location and pointing up at the satellite in the sky.
Incidence Angle	Metadata: `angleIncidenceDegrees`	The Incidence Angle is `90° - grazingAngleDegrees`.
Squint Angle	API: `squintAngleDegrees` / Metadata: `angleSquintDegrees`	Umbra Product Guide: Canopy Squint Definition
Target Azimuth Angle	API: `targetAzimuthAngleDegrees`	The Target Azimuth Angle is measured clockwise from north as measured at the target location. Not to be confused with "Azimuth Angle".
Slant Range	API: `slantRangeKm`	The Slant Range is the straight line distance between the target location and the satellite.
