So I have multiple rasters that I would like to clip to a single extent. All data is orthorectified geotiffs in the same projection. There is Identical pixel overlay. The extent I would like to clip the rasters to is where they all have data. Basically, I'm looking for the maximum area where they all have data so I can do time change analysis on the area. Now, I see where and how I can do this in arc tools, but I need a polygon shapefile in order to do so. I don't have the information to create a polygon with the boundaries I desire (where all rasters overlay).
Question: Is there any way to clip multiple rasters to where they all overlay without the use of a polygon? And if there isnt, how can I clip this data with a polygon to obtain what I am after?
Thanks for your time.
