Editors compared

Matt Amos (who should blog more) has done a really cool visualisation of the editors used by OpenStreetMappers. Blue is Potlatch, red is JOSM, green is Merkaartor, and grey is everything else.

Really big disclaimer: this is based on the created_by tag, and JOSM and Potlatch treat this differently. JOSM sets the tag whenever it adds a new object: Potlatch sets it whenever it adds a new one or modifies an existing one. So there’ll be an inevitable bias towards Potlatch. (Potlatch’s behaviour is arguably more sensible but I’ll leave that for another time!) But despite all that – isn’t the big mass of blue pleasing to the eye? Well, I thought so.
