I have some trouble getting some meta data using DIMAP Driver.<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">gdalinfo --version<br>

...<br></blockquote><br>The problem is that there is spectral info only for first band. I would like to see the data for each band.<br><br>I also made a C++ program using the API ( GDALDataset::GetMetadata and GDALRasterBand::GetMetadata           

)giving no more results. Is there some turn-around to get the meta-data using the driver ? Should I submit a bug ? Thank you for your reply. Guillaume.
