Thanks, again Christoph. You're a lifesaver. For the benefit of the gdal-dev list. Applying the below patch to GDAL fixed my build issues with HDF5 1.8.16 - diff --git frmts/hdf5/makefile.vc frmts/hdf5/makefile.vc index

Re: [gdal-dev] GDAL 2.0.2 & gpkg woes

Unfortunately, makes no difference, with my application code or ogr2ogr. I also tested the new libspatialite-4.2.0a DLL against my old GDAL build. Works fine. Alan Stewart Senior Software Engineer TerraGo Technologies 3200 Windy Hill Road, Suite 1550W Atlanta, GA 30339 USA O. +1 678.391.9615

Hi Even, The produced GeoTIFF doesn't contain any nodata metadata/flag/TAG. It simply has "NaN" pixels. QuantumGIS report those pixels as "nan" and OpenEV report them as 1.#QNAN so I think they are properly "recognized" as NaN. I'm wondering if the GDAL utilities explicitly look for some
