Mapping

Community

  • In the continuing “Mapper in the Spotlight” series, Escada publishes his interview with the mapper Dave Corey from Ireland.
  • User Glassman wants to rewrite the welcome page to encourage more participation from the newly registered users on openstreetmap.org. He is asking for more suggestions.
  • The Dutch community discusses (English) the data from the 3dShapes import. The data is from around 2002 and of course the landscape has changed since then (but was it accurate before?). The discussion continues on whether the data should be imported from newer sources or should be manually updated.
  • John Willis explains why the current OSM-based maps are not useful for map-based navigation in Japan. He further elaborates about this in another post.
  • Joost Schouppe has some statistics on the evolution of data density in the different Belgian regions.
  • Joost Schouppe reports about the meeting with “Trage Wegen“. This organisation makes the inventory of  footways, even those that no longer exist. This makes it hard to use their data, but they will try to meet on an inventory day as they are similar to mapping parties, might exchange data and perhaps also meet some potential mappers.

  • User JAT86 explains that he has left the Wikimapia project in favour of OpenStreetMap, and gives the reasons for his change.
  • Ramyaragupathy reports about Mapbox’s progress in the correction of Japanese road alignments (also reported previously).
