Hi Etienne,
firstly the problem reading the MERIS (actually coastcolour) data was due to
the fact i was using gdal 1.6, after upgrading to 1.9 i can at least list the
bands so i guess that 'works'.
regarding the use of the filesystem, i tried that, however it is slow to write
out the whole dat
If anyone is interested. I have implemented a dynamic subBlockSize. It
seems to work just fine and the memory consumption is now minimal even with
huge WMS rasters.
I have attached a patch file with the changes.

Hi Anton,
thanks for responding,
I have tried adding the tps option like this:
gdal.ReprojectImage(input_ds, output_ds, input_ds.GetProjection(),
output_ds.GetProjection(),
gdal.GRA_NearestNeighbour, 0.5*1024*1024*1024, 0, None,
{'tps': True})
but it has no effect. des

Jukka,
I highly suspect that the ALTER TABLE must imply a rewriting of the file by
spatialite/spatialite-gui, and when doing so, it doesn't preserve the
"application id" (4 bytes in the header of sqlite file), that geopackage
specification mentions to be set to a particular value. Consequently the
Hi,
There are no GUI-tools for managing GeoPackage databases at the moment and
because after all they are only SQLite db files just like Spatialite files I
thought it would be a good idea to do some maintenance work for GPKG
database with Spatialite-gui.
I could do a few things with Spatialite-gu

This is a very interesting idea.

Hi,
The default value of -gt parameter of ogr2ogr utility is 200 which is all
too low for databases. Especially bad it seems to be for SQLite/Spatialite

Are there some drivers which would suffer badly if the default value for -gt
would be increased to something like

Dear list,
I am trying to compile gdal 1.10 with the intention of adding KMZ support

If so, how can I compile GDAL to get support to KML/KMZ support? I am
