What is OpenStreetMap?
What's a Mapping Party?
- How to map an address?
- To be a contributor to OpenStreetMap, firstly register to be an OSM user 
- Addresses can be tagged with addr:housenumber=* and the other addr:* keys. Tags can be added to
- isolated nodes
- nodes that are parts of building polygons ( = entrance=*s )
- building=* polygons
- on polygons representing the perimeter of the site.
- Buildings with multiple house numbers - There is currently no consensus on this but here are some possibilities:
- Create an address node for each housenumber and place each node somewhere on the building outline (or inside the building).
- Separate the numbers by commas (e.g., "11,13,15").
- Specify the range (e.g., "10-95"). This is the preferred method when such a range is officially used for the entire house. You may also use **addr:interpolation=* to describe whether that includes odd, even or all numbers.
How to map a building?
A single building outline can be created for each building complex or 'block', which may relate to a single detached property, or to a row of individual terraced houses or to some more complex arrangement of properties. It is however better to create a series of linked outlines which share some nodes at the boundary to identify each distinct part of the property.
Buildings can simply be building=yes
If the building has an interior courtyard the use a Multipolygon relation to ensure that the courtyard is not rendered as part of the building. Please consider adding house numbers nodes to buildings with tags in addr:*=*-Namespace: entrance=yes (if you know where the entrance is)
