Adding data to OSM after Hoxton mapping party (London, Oct 2012)
That’s how the process of adding data collected during a mapping party may look like. This time I was using the following things:
• About 150 photos taken during surveying that kept lots of area details I could not fit into printed maps;
• Bing aerial, kindly provided by Microsoft − hi-res satellite imagery, a very helpful source for precise building outlines;
• Hundreds of uploaded GPS traces that were used to realign the imagery and thus compensate its slight displacement;
• JOSM (OpenStreetMap editor).
In OpenStreetMap you can use a lot more different mapping techniques, dozens of them are described on OSM Wiki.
And here’re the result of my efforts: osm.org/go/euu46tnBd--
