2014-12-10 Thread Even Rouault
Hi, I've committed in GDAL trunk the final pieces of the code needed to support GeoPackage rasters in read/creation/update modes. Feedback from early testers would be much appreciated, particularly regarding interoperability with other software stacks (1), as I could basically only test round-t
