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:


Field papers (new version of walking papers) − printed maps that you grab with you for a mapping walk and draw new details right on top of them;

• About 150 photos taken during surveying that kept lots of area details I could not fit into printed maps;

Mapcraft − a collaborative tool for organizing mapping parties (the map cake we were using was prepared by Harry Wood);

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:
