[Talk-us] scanned USGS Topo Layer?

[Ian Dees]

The "USGS Scanned Topos" layer is a cached layer based on the three layers
here:

http://raster.nationalmap.gov/ArcGIS/rest/services/DRG/TNM_Digital_Raster_Graphics/MapServer

I don't see a good way to check metadata for the scanned quads. There's
information about the "Large Scale Imagery" layer, but not the scanned
topos.
