I need to trim the collars off of many USGS 7.5 minute quadrangles for a state. I have the quads as GeoTiffs and have the polygon boundary for the whole state. I think there are about 1446 quads/Geotiffs where each matches a rectangle in the polygon. Does anyone have a script or model that will do this I can modify for my purposes? FYI, the polygon is basically a grid of rectangles.
