To clarify: doing the gdalwarp resample without OpenCL is producing a realistic Float32 value range. Doing it WITH OpenCL is producing far higher values. This is on a Tesla M2090. No other experiments/benchmarks have produced this kind of result, and as I wrote below, gdalwarp itself works when on

[gdal-dev] Odd problem -- Gdalwarp, OpenCL and interpolation

2016-03-05 Thread Jonathan Williams
Hello, I've run into an odd problem that I suspect is the result of some incorrect variable type casting, but I'm not sure where to look or how to fix it. Inputting a raster in Float32 format (or Float64, with -ot Float32 and/or -wt Float32 enabled on the command line) and attempting to do a resam
