Problems

Map looks complete at low zoom However at high zoom:

Roads are unnamed Junctions with incorrect layout Roads under trees are missing Footpath/Cyclepaths are missing POIs are missing

Lots of Mapping Evenings Every Wednesday Evening Put your name against your bit of the cake on the 

wiki page Meetup in a pub after some mapping on the way 

there Special rendering to highlight unnamed roads by

Mapping Party Results

Typically 7 mappers at the pub Regular meetup for local mappers 3 hard core mappers have now been to a 

mapping party More pubs and other POIs Central London with less unnamed streets

At the Pub

Page 24: London Mapping Marathon Lightening Talk at SOTM2008

   

Your City?

Need active OSM community, as few newbies Need good transport connections Find some pubs in/near the area to be mapped Setup a wiki page like:

http://wiki.openstreetmap.org/index.php/London/Summer_2008_Mapping_Party_Marathon

Create a cake on the wiki page Fortnightly or Monthly is a better frequency

Page 25: London Mapping Marathon Lightening Talk at SOTM2008

   

Your City?

And Hope there isn't any rain
