How can we ignore altitude? We don't have altitude data for the POIs, so I've set it temporarily to 0, but it'd be good to ignore it altogether to avoid any issues when the user is very close to a POI (and would have to point down to see the POI if the altitude is set to 0 and he's standing at an actual higher elevation).

There is a special value for not using Altitude, it's AR.CONST.UNKNOWN_ALTITUDE. If you don't want to use altitude or if it is unkown you can use "new AR.GeoLocation(lat,lon)" without supplying the altitude and it will by default be set to UNKOWN_ALTITUDE.
