Geometric Distortions
Distortion caused by Projection: Inherent in the use of 2D projection-based SRFs, where the distortion varies non-linearly with distance from the line(s) or point of projection.
- Distance (on the surface of the ERM)
- Azimuth
Distortion caused by Augmentation: Inherent in the extension of projection-based 2D SRFs to 3D SRFs, where the distortion varies non-linearly with both elevation and distance from the line(s) or point of projection.
- Distance (with respect to altitude)
- Elevation Angle
