Support for Rosetta data

Hi all,

I was wondering if anyone has attempted to use the stereo or shape-from-shading method on Rosetta data for 67P? I am trying to find out if it is possible to add georeferencing to the images to use them for DTM generation.

Thank you so much for your time,

Oleg Alexandrov

Since Comet 67P/Churyumov-Gerasimenko is a highly irregular body, I am not sure how well DEMs will work. Those assume a round body.

ASP recently gained support for creating meshes of an arbitrary environment based on pictures. See The tools are part of the daily build, only for Linux, available from

I must say that while the software is functional, and I did spend quite a time testing it, I only tested it for International Space Station images, not for a planetary body. You are welcome to give it a try, if you wish.

There are a lot of packages out there for doing photogrammetry of non-planetary bodies. See here:

I worked a bit with Colmap and I liked what it does, and I heard good things about AliceVision. These require a GPU. ASP's software does not, and it also gives more control over optimizing camera parameters, and in time will be integrated with the other ASP tools. 

In short, this is a bit outside our usual area of focus, but I plan to have ASP grow in that direction, time and funding permitting (and this year there will be some ground-level terrain work which will help with that).

To add to the previous, it appears that ISIS supports some Rosetta instruments:

I did not try these. Ideally these create some .cub files. Then, likely ASP's usual bundle_adjust and parallel_stereo tools can be used, followed by point2mesh to create a mesh. For a somewhat flat area (there won't be many of those) maybe point2dem can be used with some radii (--semi-major-axis and  --semi-minor-axis) compatible with comet radius in meters.
