Hello,I wanted to add my opinion here too. If there is an active development of GPU based warping (or any other gdal functionality) then I would like to get involved. I know the OpenCL was there for many years but I never was able to use it. Could you please elaborate about the active work by S

Hello GDALers, I have a question about reading USGS 3DEP (3D Elevation Program) data. Inside of this data, a GEOTIFF tag 42114 is provided which is causing problems with datum shifts. So when I use GDAL to compute the datum shifts, the tag is read and interprets that the DEM is showing elevati

Hello again, I fixed the compilation issue. Basically in the file frmts/hdf4/hdf4imagedataset.cpp the include statement wasn't correct. It should have been hdf-eos/HdfEosDef.h where it actually is. However, this did not solve my MISR reading issue. Have a great day, Conrad :) ___
