[Qgis-user] [pyqgis] looping through a raster (andrea antonello)

[Newcomb, Doug]

Andrea,
Why not call GRASS r.series through the python interface, average the stack of rasters there, then select the point value from the result. It's a bit brute force, but when I have used  r.series directly in GRASS with hundreds of large rasters at a time, there was fairly low memory usage.
