I'm using gdal_grid to create a 1200x796 pixel out from an input data set of
approximately
250,000 points. This takes about 90 minutes (30 minutes for each r/g/b band).
This seems
to be unreasonably slow. Any ideas on speeding it up?
The command I am using is:
gdal_grid -txe -51.428009 -43.153992 -tye 46.112598 51.347198 -outsize 1024 796
\
-a nearest:radius1=0.01:radius2=0.01:angle=0.0:nodata=0.0 \
-l rs2_file_1 -l rs2_file_2 -l rs2_file_3 \
-of GTiff -ot Byte rs2_file.vrt test.tiff
