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 ORM)
- Azimuth
Additional 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 the vertical)
- Elevation angle
