paper and pen
Actually some devices can store names of the way point. That was not the problem at all. The problem is about offsets and resultant accuracy of maps.
I mean, the to reach the shop, you have to walk good 5meters or such - at times - depending on width of foot path or such. Now those paths are not roads really, and they can vary from place to place. How to tackle such offsets ?
measure it
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.
Cheers!
