From my experience, setting the georeference but leaving the transform blank will cause applications like GlobalMapper to fail reading the file (I noticed that with jp2k but I suppose it will happen with NITF as well). Sent from my mobile Yehiyam - From: "cobalto" Su

[gdal-dev] MrSID mask band support

2011-02-14 Thread Brian Claywell
I'm attempting to use CreateMaskBand() on a MrSID dataset with GDAL 1.8.0 and receiving the error that "CreateMaskBand() is not supported on this dataset." I presume this is because mask band support was implemented using the GDALDefaultOverviews manager, and since MrSID is a multi-resolution forma

Migrating from GDAL 1.7.2 to GDAL 1.8.0, I noticed that GDALDataset::GetProjectionRef() now returns an empty string "" on some cases where it previously returned an informative WKT string. The file I initially noticed this on was a 10Jan2009 Worldview image in NITF format. The image has 2 subdata

2011-02-14 Thread Frédéric Trastour
Frank, IMHO, something that is missing in the actual build system is a way to allow the user to specify additional libraries to link with without modifying nmake.opt. It is possible to specify some include folders with EXTRAFLAGS but no way to initialize for example the ADD_LIBS variable. This sho

I personally have always just modified the nmake.opt. I am not sure what is recommended now. Can someone verify that the new recommended way is to create a 'nmake.local' file and then execute 'nmake /f makefile.vc' ? -jeff On 11-02-11 6:27 PM, Frank Warmerdam wrote: Folks, Some time ago
