Online source of Real Terrain images.

Well, I just discovered something called terrain.party. It's an online application that shows a scrollable map of the world. Yocan select from an 8km to a 60km square chuck of terrain, and download that as several PNGs (and a read me text file of relevant data) which can later be imported. It's land only - sea gets converted into a zero height, but you can select that and modify it later.

The default view (shown above) is derived from OpenStreetMap, but if the selection's in the USA you can swap to USGS Shaded Relief or USGS Topographical imagery. The output is in 16bit PNG regardless. Of course that means it suffers from all the issues that bitmap imagery does, but it's still a source for maps. Here's a heightfield layer that was imported (from the Island of Rottnest Island)with height range of 0 to 20:

...and here it is in 3D editing:

And here's the real Island (from th wikipedia):

I have found that terrain.party really squash the heightmap down. Try Earth Explorer is you have not already on side note with the cords out of terrain.party you can grab osm data files from openstreet maps.
