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
I apologize for my previous badly readable code snippet.
Here a better version with a dummy example:
# simple raster stats
cols = dtmLayer.width();
rows = dtmLayer.height();
minV = 1000
maxV = 0
count = 0
sum = 0
transformType = QgsRasterDataProvider.TransformType.TransformImageToLayer

Hello,
I am trying to understand how to easily loop through the values of a
raster layer using pyqgis.
In the docs I see the sample and identify methods of the dataprovider,
but can't spot anything that uses rows/cols as a way of iteration.
Is the most efficient way to use transformCoordinates to
