illuminationElevationAngle: real - illumination elevation measured in degrees clockwise from the target plane at intersection of the optical line of sight with the Earth’s surface. For images from a scanning device, refer to the center pixel of the image.

illuminationAzimuthAngle: real - illumination azimuth measured in degrees clockwise from true north at the time the image is taken. For images from a scanning device, refer to the center pixel of the image.

imageCondition: string - a code which indicates conditions which may affect the image. Example: snow, fog, clouds, night, blurred...

imageQuality: object - a resourceId object which specifies the image quality.

cloudCoverPercentage: real - area of the dataset obscured by clouds, expressed as a percentage of the spatial extent.

compressionQuantity: integer - count of the number of lossy compression cycles performed on the image.

triangulationInfo: Boolean - indication of whether or not triangulation has been performed upon the image.

radiometricCalibrationInfo: Boolean - indication of whether or not the radiometric calibration information for generating the radiometrically calibrated standard data product is available.

cameraCalibrationInfo: Boolean - indication of whether or not constants are available which allow for camera calibration corrections.

filmDistortionInfo: Boolean - indication of whether or not Calibration Reseau information is available.

lensDistortionInfo: Boolean - indication of whether or not lens aberration correction information is available.
