[gdal-dev] Support for MISR data processing.

Dear gdal-dev,

I have some MISR hdf data downloaded from the following website (http://eosweb.larc.nasa.gov/PRODOCS/misr/table_misr.html). I have tried to use gdal to access the hdf data using techniques similar to other hdf data sources (MODIS - NDVI and ET). gdalinfo is able to read the contents of the data file in much the same way as it does with MODIS data products. See below, however when I use gdal_translate to extract my data set of interest the result is incorrect. The command executes as per normal and writes a data set to my disk, however when I look at the result in QGIS I see that the image is flippped to the left (north now faces west) and that the data is jumbled (white noise). The command I am using is below. Any help on extracting MISR data blocks is greatly appreciated.

Many thanks,
Wesley
