Weingartnermoor Woodland Walk : SotM-EU Mapping Workshop

At State of the Map Europe in Karlsruhe I used the opportunity to develop some of the themes I have already outlined for woodland mapping. Essentially I have three lines of attack:
  • extending the cartography of woodlands in OSM ;
  • finding richer ways of tagging woodlands in OSM ;
  • looking at how we can collect data about woodlands (mapping).
I didn't do anything about the second, but gave a lightning talk outlining just some ideas about woodland cartography (I got a few more over the course of the conference). For the latter I thought the best approach would be to get some OSMers in some real woods because real things are much easier to discuss than abstract ideas on the wiki.

We spend much of the conference listening and discussing abstract ideas, and (too) little time using the fact that we come from many countries to share our knowledge of tagging. (A little Guerilla Mapping is not out of place too). So this was a small innovation for an SotM conference too.

I was fortunate in the first place that the Karlsruhe Stammtisch offered some good ideas and advice and the conference organisers chose to add the event to the programme. Secondly, I was fortunate in being supported by more OSMers than I expected: and I know I lost a few due to the early start (necessary to enable not missing the whole Hackday).

Segmentation of Retail Landuse: why do Germans only map shops?

Retail Landuse in Karlsruhe on OSM (scale 1:50k) :
both explicitly mapped and derived landuse polygons are shown, see below for methods.
The availability of lots of open data on various kinds of retail outlets has led to me doing a lot of maps of shops, restaurants, fast-food outlets and bars lately. I'm following in the steps of Paul the Archivist who mapped the Mansfield Road area close to pub meetings we had in 2011. I've got a nice workflow : I map my target area for an hour on Sunday morning, usually trying to get all retail establishments in a quite small area. I also try and collect as many house numbers as I can. I discovered my new mapping protocol, because my mother asked me to drive her to church a few weeks ago and I found it very productive. It also means I've been actively surveying in a neglected inner-city area.
