Thanks Noel - the scale would be meters rather, but I somehow assumed that this might be too small-scale for GPS ...
I guess I really ought to compare both measures, but for the GPS part, I wonder what would be the most "architecturally adequate" way to adapt 'world-updater' s contract to handle the additional geolocation field (and the other fields currently unused, possibly). ciao, Sigrid Am 02.11.2010 um 22:08 schrieb Noel Welsh: > I don't /really/ know, but isn't one reading from the accelerometer > and the other from GPS?
