For the very first time, I used OSM2Go to do some “live mapping”. What I actually did was to go to the supermarket by foot. I used the Nokia N810, an external GPS bluetooth mouse and OSM2Go to map some house numbers.
OSM2Go meanwhile has learned to use the preset file format of JOSM, so you will immediately feel familiar with OSM2Go. Thus I even mapped some further POIs, including some surveillance cams :) .
But anyway, house numbers currently are the most important thing. A navigation system without house numbers will never be a serious system, and geocoding is just another thing that must be possible using OSM data. So why not collect some during occasional evening walks? It’s dark and cold, so there’s not much more useful you can do :) .
