The source data is the original USGS DOQQ's. To see available areas, on the right side of the map interface, under the Display tab, click the arrow next to the category Layer Extent. A list of layers will appear, find the desired DOQQ Index and click the box next to it. This will automatically update the map with the index showing areas of coverage.
