I've been playing around with Open Streetmap (OSM) lately for a couple of web mapping projects. While the import to postgresql was a bit challenging, the results are great!
Here's an example (click for high res version):
I generated tiles from a mapserver-based WMS that accessed the pgsql data. I'll need to play around a bit with scale to make the text readable in the 3d rendering.

Emphasizing Points
In previous posts we've discussed emphasizing ridgelines, linework, and property boundaries.
Suppose you want to emphasize a point set. Here's a fun way by converting the points into spheres (click for high res version):
The points are raised above ground based on an attribute value. A couple of tricks help them stand out. For one, there's a nice specular reflection to help define it as a 3d object. Also, the spheres cast a shadow that helps highlight their position above ground level.

Terrain Morph
We work in a lot of areas with substantial topographic relief. Topography is often the most compelling characteristic of an area and I've found a nice way to emphasize this fact. Instead of looking at a "flat" map or 3d view, what about transitioning between the two? Here's a clip from a video that we're currently working on for Colorado's Staunton State Park:
It's a slick way of focusing your attention on how mountainous the area really is.
