3D maps

Recently, I’ve been beginning to dabble in 3D GIS, something I have very little experience with. Co-incidentally, on a recent trip through Ontario, I came across this incredible example of a 3D mine map. Each map “sheet” was printed on plexiglass, and stored in a custom cabinet, lit from below, so they are below so the structure and relationships between the levels of the mine could be examined. A pretty great example of 3D mapping before it was commonplace.
