Research direction
Start by reviewing the view extension and the perspective-imagery extension referenced in the issue, focusing on how off_nadir is defined and constrained to 0–90 degrees. Compare extending off_nadir to 180 degrees with adding an elevation angle, then confirm the preferred representation and its schema implications. Done means the chosen approach is agreed and consistently specified.
Written by the indexing model from the issue text.
Description
The perspective-imagery extension recommends using the view extension, but that doesn't work well for some perspective imagery in that the off-nadir angle (which is essentially a way to represent elevation angle) is limited to the range 0-90 degrees.
If the off-nadir angle could be extended to to 180 degrees, it would be able to represent the case where the camera is pointed slightly (or very) up.
As an alternative, a more natural representation would be an elevation angle from camera local level, where positive is above the local level and negative is below. This would be redundant with off_nadir, in that 30 degrees off nadir is equally -60 degrees of elevation angle.
Any preferences for either alternative?
