[OSM-talk] using SRTM contours when editing

Just wondering whether there's any way that I can display SRTM contours in JOSM or Potlatch when editing? It would be useful for placing features such as natural=peak and waterway=stream where you have local knowledge of an area but aren't able to go wonder round with a GPS. I know it wouldn't be as accurate as GPS surveying, but I'd still like to be able to refer to it.

Thanks,

Dave
