[gdal-dev] Using GPU for GDAL Python

Hi Folks, good morning! I'm using GDAL Python for pre-processing some satellite images, currently using CPU instances in AWS. I'm struggling to find a way to implement it using GPUs, more specifically, the NVIDIA V100 GPU. Does any one achieve that and could share how you've done it? Thanks, Pau

Re: [gdal-dev] Writing multi-bands vs multi-datasets

On more. The warning about "No 1D variable is indexed by dimension time" turned out to be because I was calling Gdal.setmetadataitem(ds, "NETCDF_DIM_EXTRA", "{time}") (like you call '{time,Z}' in your Python example). Removing the curly braces here made that warning go away. From: gdal-dev On

Re: [gdal-dev] Writing multi-bands vs multi-datasets

Much better (I was confused by those curly braces thinking it was part of python syntax). Though still get this warning Warning 1: No 1D variable is indexed by dimension time But otherwise gdalinfo does not complain on anything wrong The "-co" is confusing. I had to add in other situations othe

Re: [gdal-dev] Python gdal.Translate(...) and unicode in Band Descriptions.

Re: Problem 1 - Following a thread “Unicode support in GDAL”[0] I tried adding “ENCODING=UTF-8” but the COG driver doesn’t support it. So I’ve taken the practical route out of just spelling out micron instead of using the symbol. For Problem 2 there’s a new wrinkle: in spite of the warning about

[gdal-dev] polygon union

Hi list, I know how to union two polygons using Python's ogr. feat = ogr.Feature(lyr.GetLayerDefn()) feat.SetGeometry(collection1.Union(collection2)) But I need to do this in Java or use a command line exe, and I am not familiar with Java. What is the Java function or a command line exe ? T
