Hi Trent, Just wondering, as even ISIS does not import it, do you know any guys actually reading the rings images? What software do they use? It might be worth just clarifying how they actually read them, even just for the sake of pds2isis and sanitizing the gdal driver ... Cheers, Yann On 9 Dec

Michael, 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 *not* 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 t

An old bug (or lack of implementation) that supposedly was fixed in GDAL 1.9.0 as mentioned in this message: http://lists.osgeo.org/pipermail/gdal-dev/2014-July/039508.html might have crept up again. Or, possibly, it is just another version of the endless parameter space of the format of PD

Hi Even, Thanks for the quick reply. I should have mentioned, that I also tried converting it to a compressed tiled Tiff. There i can see the same kind of overhead. I extract a 1MB Subset from the File and depending on the Tiles 1 read between 9-12 MB via the Network. The Process only reads o

Dear Gdal-mailinglist, I am currently trying to optimize a Global Modell. The Modell reads small chunks (500x500) from lots (One for each day) of Global Datasets (4x2) These Dataset are compressed NetCDFs with a tilling activated (100x100). (See output oif gdalinfo attached) However whe
