Fascinating.

I think working on the barometric pressure thing would be fascinating, and I think we’re probably at least as qualified to do the work as anyone else.  Perhaps we could get the OGC to work on in with us.  I think of that as combining the existing elevation datasets with building floor height data to produce a floor number from the barometric data.  I’d guess some compensation from weather data would be needed.   Crowdsourcing might be interesting, but what would we use to actually get the right data (how does the source know/enter floor data?)  Hah - sound analysis on an elevator ride!  Listen for the dings and floor announcements.  Watching steps and pressure is probably a decent way to figure out what floor you are on if you walk up a stairway.
