This is a 22 piece 3d topo map of Yosemite Valley which I showed at the San Mateo MakerFaire. Each piece is a 2km square chunk. The STL files are scaled to 100mm square making the overall scale 1:20,000. The individual models are detailed enough that they could be printed at at least double their size without getting "voxelated". I tend to print small sections to avoid the distortion which sometimes comes with larger prints.

There is a diagram showing where each piece fits so you could print only your favorite landmarks, or start with Half Dome and work your way down the valley like I did.

The final model is more than 2 feet long (0.7m to be exact). There is no real reason to stop here except that the high resolution Lidar survey data goes no further. The data comes from http://opentopo.sdsc.edu/ where you can freely download amazingly detailed datasets from around the world.

We talked about this thing and a whole lot more on the 3D Printing Today podcast available on iTunes, Stitcher radio or direct from the source at http://threedprintingtoday.libsyn.com/

The technique for making these models is detailed in my youtube video https://www.youtube.com/watch?v=t4-ICkvyJv0.

What slicer and settings do you use? Slic3r looks to generate incorrect GCode?
[edit] Slic3r 1.2.9 seems to be bad, but Slic3r 1.3.0 seems to be OK.

Do you recommend a feedstock to print out this model, e.g. manufacturer and/or color, or even PLA vs. ABS? I'm interested in printing out the easternmost sections covering Half Dome and Glacier Point (C5, C6, C7, B5, B6, B7)

Where is the diagram, please?

One of the pictures above shows the layout of the different blocks if that is what you are looking for.

Any chance of getting D3,A5&6?

I skipped those because there wasn't much lidar data in those quads and the survey has a funny irregular edge which I didn't like.
