2020-03-05 Thread John Daniel
Hello everyone, I am investigating adding support for Apple Metal to GPU resampling in GDAL. This is what I've learned so far: 1) Currently, OpenCL is only used for resampling operations via gdalwarp. RasterIO resampling via gdal_translate does not use OpenCL. This makes gdal_translate, and

Hi Sean, Thanks a lot for your answer! It works for me. I have one follow up question: is there a way to make the background transparent instead of being white? I really appreciate your help! Best regard, Guodong From: gdal-dev On Behalf Of Sean Gillies Sent: Thursday, March 5, 2020 11:24

Hi all, While upgrading some Python software from using GDAL 2.3 to GDAL 3, I've come across this snippet of code: srs = osr.SpatialReference() srs.ImportFromEPSG(102008) This used to work, but now fails with GDAL 3 / Proj 6 with "crs not found". Projection code 102008 corresponds to

Hi Frank, your question is not about GDAL but about QGIS and should be asked in the QGIS-users mailing list. Your issue is that you are using online DEM source. You should first download it to the local machine and only then call Processing algorithm against saved file. Hope this helps. чт, 5
