Georeferencing Parameters
From DGIWG
The properties of Georeferencing Parameters are listed below. The intent is not to enable geopositionning of pixel but to enable discovery of imagery data, on the basis on acquisition information.

|---|---|---|---|
| azimuth
[DMF/Sensor]
|
Instrument Azimuth
Horizontal angle to the measuring instrument counted counterclockwise from North (source ISO 19159-1). It is expressed in decimal degrees.
Note: This angle should be measured at the center of the image.
Constraints: * mandatory for radar

| elevationAngle
[DMF/Sensor]
|
Instrument Elevation
Elevation angle between the horizontal plane and the line of sight, measured in the vertical plane.
Note: This angle should be measured at the center of the image.
Constraints: * mandatory for radar
