Hi,
I have been using gdal raster Calculator because it is much faster (but less flexible) then QGIS internal calculator. I know that R has a raster package but I have seen reports of this being slow also. Look for R Raster package.
Of course, hopefully there may be a answer found here. If so, I would liked to be kept informed on this conversation as my data will soon get much larger.
Thanks!

Dear GDAL Developers:I am doing raster calculation by reading the bands as numpy array, doing numpy calculation, and writing back the numpy array. But seems pretty slower, what is the faster way to do it?
