That might be possible ( if at all ) if I am doing nothing else but mapping, but not when I am on my morning/evening walk or just going from one place to another in a vehicle/train/whatever ( and mapping on the sidelines ) and can't stop to do such measurements. Plus, what would be the use of such measurements anyway? My concern with offsets is the accuracy of the resultant map and positions of waypoints ( shops/schools etc ) on the map.
Is there an easier way of mapping by using high resolution maps from googlemaps or any other provider
copyright problems with google maps - we have to make do with yahoo images
Thats not a problem. The main part of the solution is to optically mark lamp posts and building tops with optical patterns that represent coded text. The lamp posts provide the road path and buildings the content. Since the satt. is already in space, the only manual labour is to plant plastic or wooden sheets painted with pre-programmed codes. The satt. camera image is then processed in something like an OCR and we get absolute accurate maps with no errors.
