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

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

Hello GDAL-experts,
normally when I use GDAL for reprojecting imagery, the projection information
that I use is the source spatial reference (SRS) associated with the imagery.
However, now I have imagery which is lat/lon geogra

convert to a georeference raster, and warp it.
If it is not the case, you have something more like a 2D pointcloud, or a
bunch of poins in a strange vector format.

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
