Use the source:geometry=* tag to indicate the source of the geometry of an object added to OpenStreetMap. Geometry in this case means the shape and position of an node or way. If added to a way there is no need to add the tag to the individual nodes that make up the way.
- This tag is especially useful when an objects geometry has been imported as it helps to keep a record of where the original data came from.
- The tag can also be used when tracing from aerial imagery, however you may wish to add a source to the changeset instead.
For tagging sources of other non-geometry information see source=*.
Tag source:position=* is used for the same purposes.
How to map
- Main article: Key:source
Values and usage are pretty much same as with source=* key:
- source:geometry=Bing + source:geometry:date=2012 — object was traced from Bing'12 imagery. Please note that Bing imagery date is not the same date when you trace it!
- source:geometry=survey + source:geometry:date=2014-11 — you can use current date if you place objects based on current information and your personal observations in OSM.
