Getting closer to the final product (I better hope so, I'm presenting it in 2 days). Here you can see the three images of the eventual survey. These three images represent the same tilemap data rendered using three different methods. The first displays no height data whatsoever. It will be used as a control against users that guess at random. The third is an isometric map that makes the height of the hills very apparent, this will be used as a control of the effectiveness of the solution (will users be able to pick the hill as easily as normal). The second image is the experiment.
