ImagingDeviceExtensionComputeGroundSampleDistance Method

Compute the ground sample distance representing a measure of the ability of an imaging sensor to detect a target on the ground.

Namespace:  AGI.Foundation.Platforms
Assembly:  AGI.Foundation.Platforms (in AGI.Foundation.Platforms.dll) Version: 22.2.414.0 (22.2.414.0)
public static double ComputeGroundSampleDistance(
	AzimuthElevationRange relativePositionFromTarget,
	double focalConstant


Type: AGI.Foundation.CoordinatesAzimuthElevationRange
The azimuth elevation and range coordinates from the target to the camera.
Type: SystemDouble
The focal constant of the camera (detector pitch divided by focal length).

Return Value

Type: Double
The value of the ground sample distance.
The AzimuthElevationRange can be obtained from the GetAzimuthElevationRangeEvaluator(VectorDisplacement) or constructed directly by creating it from a Cartesian representing the relative position expressed in the AxesNorthEastDown orientation.
