help with script to clip or trim collars from USGS quads...

[TomCarlson1]

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.

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

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

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
