Re: [Paparazzi-devel] UAV position in paparazzi GCS

[Bernard Davison]

Dont discount the thought that google maps/earth could be wrong for this area.
At my home google earth/maps is very close but at my parents farm the images 
are way out of position 40-80 meters. Images of a creek are positioned on the 
side of a hill!

Cheers,
Bernie.
