Currently the data isn't available outside the app, but I'm working on that and should have that out within a couple of weeks. My focus so far has been growing the user base, so the web interface has lagged. Coming soon! For elevation, we currently attempt no fixes. The attitude I've held so far has been that this is the primary reason for building a _network_, since a single barometer cannot be trusted. However, your Manhattan scenario is interesting: what if most people are constantly changing elevation? Hm. I'll work on that one...
