[gdal-dev] DIMAP format questions

[Matt.Wilkie at yukon.ca]

Hi All,

I'm getting conflicting information about the contents of some of the SPOT imagery we've received. Can someone here verify that this archive[0]   contains ortho-rectified stereo imagery? If yes can gdal use it? how?  The conversions I've tried so far use the RPC info but not the GCP, if indeed the files named GROUND_*.XML are GCP.

In the process of working with these files I've come up with number other questions also. They pretty much can be rolled up into: what information is present but NOT handled and/or carried forward by gdal?

For instance aside from the GCP question, there is a MASK folder which contains GML files of Clouds, Region of Interest, Saturation, Snow. I've used ogr2ogr to create polygons of them but have not discovered how to georeferenced them so they can be used with the images.


[0] I've applied a 50 pixel radius Gaussian blur to the multispectral and 300 radius to the panchromatic TIF files. So there should be no intellectual property concerns about keeping this archive as a test case. I used Photoshop to apply the blur. If that introduced something unwanted I can reapply using gdal-calc or similar if someone wants to provide a command line example. All other files were left as is.

thanks in advance for your thoughts and time,
