Robin,

Can you provide a pointer to a sample dataset?

Will try to find a freely redistributable sample.

Milestone: 1.8.0
Status: newassigned

I have made a preliminary implementation of georeferencing support from the MTL file in trunk (r19427) and 1.6-esri (r19428). The provided sample data was a raw image product, so all I was able to capture for georeferencing was lat/long corner coordinates. If I had a map projected image, I could fill out the support for setting the geotransform.

I did not capture any other metadata from the MTL file, though there are some other items that might be of interest.

Robin extended the MTL support in the 1.6-esri branch to support either L1_ or LPGS_ prefixes (r19487). I ported this into trunk with a few cosmetic changes (r19494).
