There has been a lot of chat on the HOT list about validation and a lot of that has focused around tools that new mappers use. It is obviously tiresome for validators to be squaring buildings endlessly or dealing with validation issues that would have been picked up by the original mapper at the touch of a button in JOSM, but that are invisible for those using iD.
In response, we have decided to start trying to work out better and quicker ways of moving people to JOSM at the London Missing Maps mapathons.
The first try at this happened in May. Using the eventbrite system to register participants to certain categories of ability has been our modus operandi for a while, so we simply upped the percentage of places available to those who wanted to learn JOSM and reduced the iD places. We also emailed ahead to our JOSM-experienced mappers to ask if they would mind making an effort to sit with, and support, the newbies.
Robert led an impressive, three hour walk through that mappers could dip in and out of and answered specific questions as he went.
From chatting to people there, not as much actual mapping was done. Despite asking all people to download and install the software before they came, there was still a fair amount of troubleshooting to do in this respect. We will see how the validating goes on the task we tackled. Feedback from validators looking at this task more than welcome!
I’d also love to hear from others organising mapathons where JOSM is the primary tool and from new mappers who have learnt to edit OSM with JOSM, or a combination of JOSM and iD. How did it work for you? What kind of training or resources worked best? What elements of the tool is it important to learn first? Any other comment?
Looking forward to taking this further…
