ArcGIS v10.1 ModelBuilder
Using ModelBuilder and map algebra, I want to compute a ten year average grid from a stack of 10. The problem is that only 1 grid (%raster%), the last one through the Iterate Rasters tool, is available as input to the Raster Calculator tool.
I am using the Iterate Rasters tool to go through a folder of asc grids. The folder contains ten subfolders, one for each year from 2001 to 2010, inclusive. Inside of each of these are twelve asc grids, one for each month. The monthly grids have identical names for all years where the number indicates the month (e.g., name07.asc). I am using a wildcard that works to successfully iterate over the grids (e.g., ten "July" grids), and define the projection for each; However, the raster calculator then only accepts one of these grids instead of all ten.
Is it possible to use the Iterate Rasters tool with the Raster Calculator tool in ModelBuilder?
