I am trying to create an automated ArcMAP (10.1) tool that will read in a file (ASCII most likely) of maximum and minimum lat/long values along with some additional variables. The tool will iterate over each row of this file, and run the processes on the unique variables each time.
A preliminary tool that only runs on one set of variables works perfectly.
However, the 'Extent' Data Type can't accept variables into it (in any way I have found out at least). So I have no idea how to define a unique processing extent for each run of the tool. Below is an example version of what the model might look like (I have tried several different ways, this is just one).
If it matters, I have never tried working with python scripts in ArcMAP, so I'm hesitant to go down that route unless it's fairly straight-forward. Unless there is no other option. The base DEM I will be using will cover the entire globe, so it really is necessary that I only process a small part of it each time I run the tool.
