That's the reason why altitude information is not yet available.

Altitude values from the Big Google Network is indeed not an option, although I guess that knowing the activity and having a toggle option would be enough to decide wether ground altitude will be used or not The goal is to use the SRTM database instead and make sure that it can also be used offline. The Google Observatory method, besides requiring an internet connection to spy you, is limited in terms of number of queries.

On the other hand, you propably don't want to use altitude values pulled off google maps, since you cannot know that the user isn't airborne, as hang-gliding for example
