Generating a polygon feature class from a Raster Catalog's footprints

I have an SDE managed raster catalog.  An external user wants a county subset of the 3500 tiles that make up the 500GB catalog.  Is there a way to merge the Raster Catalog wireframe or foot prints with polygon layer?  I just want a list of tiles that are covered by two counties.  It is going to be a large number a tiles but I still have the TIFs on another hard drive. 

If I can generate a list of tiles I'll convert that into a bat file that copies the original TIFs to an external hard drive then build a new raster catalog of the subset.  If there is an easier way to do this I'm all ears.

Hello there,

This workflow may work for you.

1) Add the 500GB catalog to ArcMap table of contents
2) Make a selection on the 3500 tiles through the raster catalog attribute table.
3) Right click on the raster catalog in the table of contents and choose Data -> Export Footprint.
4) Then run the Copy Feature GP tool, copy the footprint to a feature class.

Then you can use this polygon feature class to merge with other polygon layer.

If the ultimate goal is to have a new raster catalog of the subset, you  might want to check out the tool, Copy Raster Catalog Items.  It honors selections on the input raster catalog. 

The Data > Export Footprints option is only available in ArcGIS 10.

  Thank you.  I have 1 PC running 10.0 so I did the Data > Export Footprints.  Worked great!

If you are scripting or using ModelBuilder, the Copy Features tool will create footprint polygons if you provide it a raster catalog as input.
