I am presently targeting Australian ‘leisure=pitch’ that don’t have a ‘sport=’ tag and trying to identify the sport and add the tag. Why? Well I added the osmwiki page for ‘sport=netball’ having found these to be missing or incorrectly tagged while some 1,300 were in the data base. I then went around adding them, or correcting incorrect entries where found. In doing this I noticed that in these areas sports grounds were poorly represented or tagged. Using the web to look for netball courts resulted in a doubling of the number of netball courts in the OSM data base! So how to find these areas where sport is not represented as good as it could be? I chose to use taginfo and search for leisure=pitch and sport!= (tags with leisure-pitch and no sport) while this works .. there are a lot of them … meaning the work spreads over several days and I was repeatably looking at the same things! So i chose to add the tag ‘fixme=sport=?’ to the places where I could not identify what sport was played there. The search can now be ‘leisure=pitch and sport!=* and fixme!=*’ and that removes the places I have looked at.
I have now done NSW! I am targeting Melbourne, then country Vic. Then … S.A./Qld.
This has increase the quantity of sports … netball is now around 3,800! Increases for AFL, touch_football (I have yet to add a osmwiki page for this), cricket, basketball, softball (yep .. needs a osmwiki page too) and discus, hammer throws and long and triple jumps (again .. needs a osmwiki pages! ).
