Imagery Service Analysis

Analysis of OpenStreetMap changesets that use imagery services from the imagery_used column. The imagery tag is set automatically by iD, Vespucci and Go Map!!. As other editors are not using it and iD is vastly more popular than other relevant editors this graph is very close to 'market share of iD by edit volume'. JOSM users are typically using source field to note actually used sources.
