Geographic coordinates (lat / lon) for other planets?
« on: March 02, 2018, 08:05:54 AM »
I am attempting to use Photoscan with imagery from the Lunar Reconnaissance Orbiter. There are of course some hangups!

If I add lat / lon data to my photos (via EXIF or XML), is there any way for me to tell Photoscan that this is selenocentric lat / lon rather than Earth lat / lon? The main difference is that the radius of the body is much smaller (1737 km instead of 6371 km).

If not, I guess this is a feature request to support planetocentric and maybe planetographic coordinates.

And then, of course it (LROC) is a pushbroom imager... but I'm hoping it can be approximated as a frame camera if I crop small enough.

Hello foobarbecue,

You may need to create custom coordinate system (for example, by altering WGS84 parameters in the coordinate system editor dialog), however, I can't suggest proper parameters.

Oh, right, thanks! I had already done that and forgotten about it. For some reason I was thinking you could only set the projected coordinate system but I am using GCS_Moon_2000 instead of WGS84 in "Coordinate system" under Reference Settings.
