I think the step you are missing is to run the model. 😄  The model lists ani_mor_1 because that is the first feature class the iterator can see.  It does not list each feature class it is going to iterate through.  Think of what the model builder window would look like if you were iterating through thousands of feature classes...What a mess.

The errors were more likely due to size limitation of ArcGIS than my computer components.  I've since found a workaround for the DEM where it's no longer a 1+ GB file (although my coworker recently informed me that it IS possible to process a DEM greater than 1GB).  I would imagine your setup is quite adequate for what you're doing.  For comparison purposes, the coworker that recently discovered it was possible to process a DEM greater than 1GB, is using a laptop that is more than several years old, which I would guess has a similar setup as your desktop. I'm not entirely sure how you came to the conclusion that there is some size limitation imposed by ArcGIS, but there is not.  Certain formats have size limitations. Tiff comes to mind, but even the old 4gb limit has been overcome with the advent of BigTiff format which ArcGIS is capable of writing.  I've been working on some hydro things since the beginning of the year, specifically processing NHDPlus v1 data for the lower 48 states.  I routinely process data with ArcHydro that is in excess of 8-10GB.  Outside of my hydro work, I do a lot of testing on NED data, which is several hundred GB's of data.  1GB of data is really nothing much these days. My test machine specs: Windows Server 2008 R2 64 bit, ArcGIS 10.1 6GB RAM Intel Xeon W3550 @ 3.07GHz Best Regards, Eric ... View more

Marie, To "Use elevation values in the layer's features", the feature class must be Z enabled - Z's stored in the Shape field.  If all you have is an attribute for height ( you have a 2d feature class) then you must select the option "Use a constant value or expression", then open the Expression Builder dialog and select the appropriate field containing your height values.

Mark, You could try Copy Raster instead of Data > Export to see if that is a viable workaround.  I can't reproduce the issue you are experiencing, but it certainly looks like a bug. Eric ... View more

Elaine, The in_value_raster parameter would be the temperature rasters that you are trying to get the average monthly temperature of per polygon.  This would require you to have 12 temperature rasters; one for each month.  Each time you execute the tool it would return the average (mean) temperature per "Input feature zone data".

You select the raster you want to Clip/Mask in the Image Analysis window (IAW), from the list of rasters.  You also select a polygon (feature class polygon), and then just hit the Clip or Mask button in the IAW.  The layer is temporary by default. ... View more

No problem Mark.  I just didn't want you to keep having to start blank maps.  Is there a reason why you're going through this 'convert to graphics' workflow rather than just hitting the Mask button on the Image Analysis Window?  I mentioned this method well before Jeff S. replied to you -technically it was even before you posted the question.  Maybe you didn't read the whole thread.  You can also Clip with the Image Analysis window - all you need to do for both is select a polygon from your feature class. No conversion to graphics required. ... View more

Mark, To get rid of the graphics you created, just select them and hit the Delete key. Eric ... View more

Jamal, One more thing.  I looked up the nested error, "Error 010422" and found it is related to the Mask setting in the environment settings.  So even if B does line up with Elevation, if you have a mask set in the environments for some other location that doesn't overlap either B or Elevation, the tool would fail with this error. http://resourcesbeta.arcgis.com/en/help/main/10.1/index.html#//00vq0000000s010422 Eric ...

Writing to the default geodatabase should be fine, but you could try GRID if you want.  The rasters do not have to have the same projection either, although recommended.  What is more revealing to me is the geodatabase you provided.  There is only the A raster which isn't one your trying to add, but nonetheless I noticed that it doesn't have a spatial referenced defined.  Also, I went back to your screenshots and noticed that even though Elevation is the 3rd layer in the map, it is always the raster being shown behind the other dialogs that are open.  This begs the question...Does B even line up with Elevation?  Or is too much of the display being hid by the other dialogs in your screenshots to see that B is a subset of Elevation?

First, you have to tell me what you mean by "not working".  Is there an error?  Is the output wrong?  Have you tried running the Plus tool instead?  Eric ... View more
