Mark what you want as waypoints .so its always a good decision to carry a notepad and a pen while mapping. > > I mean, the to reach the shop, you have to walk good 5 > meters 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 ? Offsets can only be tackle when you are actually editing the track for maps . JOSM , potlaych , mapnik all provide presets for this .again pen and paper comes to help . > > 2) Suppose you have tracked certain part of your town or > your route from your home to airport near your city.

Is there a way to avoid that / > tackle that ? well just dont put that part while editing the tracks/routes . its always better to mark waypoints of imporatnt cities in between routes . atleast thats what i did from delhi to kolkata and off course take help of yahoo maps as the collaborate with OSM with thsi regard . more details can be found at osm-talk list > > Any pointers ?
