<div dir="ltr">Michael,<div> This is an odd hybrid PDS/ISIS2 label. Before seeing this label I have only ever seen the "QUBE" label object within an ISIS2 file. This was <b>not</b> one of the PDS label options -- at least when the gdal reader was written. For rasters files within PDS (v3), as far as I understood, only the "^IMAGE" or "^SPECTRAL_QUBE" were allowed. I don't know the heritage of this label or when it was implemented but it is a strange beast. This is one reason, among many others, that I have always placed a caveat on the GDAL PDS readers that it probably supports about 70% of PDS images. It obviously doesn't support this type or if the image section is compressed (e.g. MOC edrs), and it will always prefer if the image is map projected and the target is a planetary surface. This PDS label is not only an odd PDS/ISIS2 hybrid label it is an image of planetary rings(!) -- I think.</div><div><br></div><div>As a check, the PDS importer in ISIS3 also fails.</div><div><div>mag{8}> pds2isis from=FUV2004_183_03_24.LBL to=test.cub</div><div>**PROGRAMMER ERROR** Unsupported axis order [AXIS_NAME = (BAND, LINE, SAMPLE)].</div></div><div><br></div><div>Anyway, to possibly read the image you might be able to hack the label but this seems dangerous and would be probably still be missing something needed from the label (even though it kind-of works).</div><div><br></div><div>change</div><div>1.) ^QUBE to ^IMAGE</div><div>2.)

<div>An old bug (or lack of implementation) that supposedly was fixed in GDAL 1.9.0 as mentioned in this message:</div>

<div><br></div>
<div>might have crept up again. Or, possibly, it is just another version of the endless parameter space of the format of PDS3 binary files that the PDS reader understandably could not yet account for until somebody tried it on this older data.</div>

<div>I am trying to read the Cassini UVIS data file in this linked zip:</div>
<div>
<a href="https://dl.dropboxusercontent.com/u/139035/PDSdata-2014-12-08T17-04-46-08-00.zip" style="color:rgb(0,128,255)" target="_blank">https://dl.dropboxusercontent.com/u/139035/PDSdata-2014-12-08T17-04-46-08-00.zip</a><br>
</div>
<div><br></div>
<div>and am getting the same errors as mentioned in above forum post:</div>
