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.
Solved! Go to Solution.
First of all, Why Clip?. You will just create new datasets taking up more space to store and manage.
Instead create a mosaic dataset and set the footprints to be the sheet extents. The sheets will then be virtually clipped and you get a mosaic without any new datasets. Just create a mosaic dataset. Add the sheets. Then use Import mosaic dataset geometry using a link between the file name and the sheet cut.
For more details and scripts to automate the process see Image Management Workflows | ArcGIS Resource Center which links to esriurl.com/6539
Also note that most of these topomaps already exist on ArcGIS Online as time enabled web services see

totally untried but from ArcScript 2.0 beta worth a look, otherwise you will have to scan GeoNet for "batch clip"

Peter, thanks and I'll try this. I am well aware of the topomaps you refer to as well, but this is something different, new data, not older stuff.
Hi Tom,
Have you seen this? http://historicalmaps.arcgis.com/usgs/
We have an entire workflow build around processing, clipping and serving scanned raster images like Topo.
You can download the app from github: Esri/map-collection-explorer · GitHub
