Digital ortho quads and quarter-quads for Washington State

As of October 30, 2002, all DOQs and DOQQs are beautifully indexed.
We also have some Oregon orthophotos. They are not shown on the map, but can be found in the Washington tables, or in Baker and Canyon City.


The three lost CDs have been replaced, and the files put on line in their proper places.
