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

wing: 1.  A bad tiff (this is slightly smaller; they are all pretty big). 2.  A GDAL info dump (survey feet is almost at the bottom) 3. A PDF with an explanation of the issue thanks for your help. Conrad On Thursday, March 21, 2024 at 04:49:57 PM EDT, Even Rouault wrote:

[gdal-dev] USGS 3DEP (3D Elevation Program) - feet should be metres, how can I fix this?

2024-03-21 Thread Conrad Bielski via gdal-dev
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
