How do I average a set of rasters?
I have remotely sensed chlorophyll a rasters for several days and I need to get an average of the days represented as one raster layer.
I am using ArcMap 9.2.

in ArcMap 9.2 using the Raster calculator (Spatial Analyst).
for five raster files:
( [raster1]+[raster2]+[raster3]+[raster4]+[raster5] )/5

5The syntax in the raster calculator in QGIS is also pretty much similar. Commented Dec 27, 2012 at 11:48

Thanks so much, I thought I had tried that but must have been typing something wrong! All sorted now :) Commented Jan 4, 2013 at 8:12
I can confirm that the Raster Calculator resulted in the solution I was looking for. I've attached an image of the tool for reference. Thank you
