Dear Friends,
In respect to the creation of high detailed maps, I plan to scan some ordnance maps of my town and local area. These are extremely detailed and I will probably manage to make my town screen filling, covering an area of some 2 by 2 miles.
I think the most accurate way of getting the right coordinates for the INF file is to actually drive to the upper left corner point on the map and read GPS coordinates at that point. Secondly you drive to the right lower corner and read the coordinates over there. Using this method elimates any inaccuracies which has been made by the producers of commercial maps.
It should be possible to get an accuracy within 50 yards or so. The same device which is used for position reporting on a map has been used for calibriation of the same map.
More accurate would not be possible, would it?
Any reactions on the above idea are welcome.
