What is OpenStreetMap?

  • OpenStreetMap (OSM) is a world-wide collaborative project aiming at providing free map data, under an open license, to anyone who wants it. Volunteers all over the planet, like you, contribute their local knowledge and their time to build the best map ever. The data in OpenStreetMap is as diverse as its contributors; it serves motorists, cyclists, pedestrians, seafarers and canoeists alike.
  • You can map much more than just streets. Building outlines, landcover, waterways, railways and civilisation amenities have their place in the database, down to individual trees, opening times of shops, or even indoor building layouts. Wheelmap helps people with disabilities, Niantic uses OSM data for Pokemon Go, and Kurviger can show routes for motorcyclists that are more curvy and outside of residential areas. There are many more examples how the data you contribute is used.

Isn't mapping complicated?

No. The world of OpenStreetMap consists of three basic elements. Points (nodes), lines (ways) and areas. They get their values through so called tags (like name=Στέκι Μεταναστών). For example,

How can I edit?

  • We have two main editors for mapping with a PC. iD and JOSM. JOSM is an advanced standalone editor but it might be better to have some experience before you begin mapping with it.
  • To add things with your mobile phone you can use OsmAnd, Vespucci or Maps.me, which also display the map you help to create. You can also use StreetComplete or Cityzenapp for Android to add information to existing stuff on OSM.

What are some "unwritten" rules?

  • Map what's on the ground.
  • Have a look in the Wiki, nearly all tags are described there.
  • Copy from other parts of the world, where something is already mapped. Germany is mapped in great detail.
  • Don't copy from copyrighted sources like Google Maps.
  • Ask! Other mappers will help you, ask on help.openstreetmap.org or on country-specific OSM mailing lists and IRC channels
  • Don't use the name tag to describe the object. For example, name=bench, instead use amenity=bench. Use tags to classify objects instead of name. Name should only be used for features with actual names, like buildings or restaurants.

What is considered good mapping?

  • Good Practice tips
  • Good Changeset comments
  • Connect footways with streets. Only things that are connected can be used for routing.
  • Don't connect landuses with streets. It's hard to change something afterwards and also confusing.
  • Square buildings.
  • Check if the satellite layer is misaligned. Compare the satellite layer with existing streets and gps traces.
  • Don't delete stuff. First ask the mapper why he did something the way he did. Maybe you just have old satellite data.

Notes to myself about data entered:

  • 201603 Piraeus_port: Added areas of covered taxi stands as sun shelters and the taxi stand as a seperare POI to emphasize on the map positions when one can find cover from the sun. These areas might be alternatively (or more appropriately) tagged as public_transport=platform + amenity=taxi + covered:yes
  • 201603 Piraeus_port: Added tickets shops (kiosks) inside the port & tagged them as "disused" as I don't know their current operational status yet.
