- I don't know of any program to automatically combine them. The
- images in a RGB triplet are not aligned geometrically so you
- can't just combine the three images with one image per color
- plane. You have to adjust the position of each until they align.
-
- Magellan's images are SAR based, and therefore monochrome.
- I'm not sure about MO. I think it will produce color images,
- but my references are at home.
