Datasets:
Incomplete geospatial information for CTX patches?
First, thanks very much for putting together this very nice dataset! It certainly makes it much easier to try and iterate on this sort of method. One problem I am having though is that I am having trouble reconstructing the exact geospatial extents of each patch in the dataset. It doesn't seem to be in the .tif files. This makes it hard to augment it with other datasets. For example it would be quite interesting to see if adding an input layer with patches from the 200m HRSC/MOLA global DEM would help the model performance, but for that we need to be able to transform and align the data.
Ah if you could include illumination metadata for the CTX images (available from the Mars ODE archive) then this would be very handy as well. One can look up the metadata for the CTX images using the product codes you preserve, however your preprocessing steps such as verticalisation mess up all the angles, and you don't record per-patch what angles you rotated the images by. The illumination metadata would be very useful for helping a model to interpret shadows and shading properly.
