But I think that for GDAL 2.0, it could be wise to upgrade to 64 bit integers to express image dimensions and windows, for example to cover the case of a WMS or WMTS server with potential world extent at medium resolution, and very high resolution in some areas with < 15 cm accuracy, which is no longer something theoretical. We would have issues for now with the current design of the block cache due to a really high number of potential blocks in such a huge raster, but that's an internal detail, and I think Tamas had a patch to improve that. > > Doug > > > > > > > > _______________________________________________ > > gdal-dev mailing list > > gdal-dev@lists.osgeo.org > > http://lists.osgeo.org/mailman/listinfo/gdal-dev > > > > > > -- > Doug Newcomb > USFWS > Raleigh, NC > 919-856-4520 ext. 14 doug_newc...@fws.gov > --------------------------------------------------------------------------------------------------------- > The opinions I express are my own and are not representative of the > official policy of the U.S.Fish and Wildlife Service or Dept. of the > Interior.
