[Openstreetmap-dev] Adding street data

[Preben Mikael Bohn]

I've got hold of ~50 MB of data from the danish mapping agency (under a
free distribution license) which relates each address in Denmark with a
WGS84 position. No roads and other attrbutes (one-way streets, major
roads, etc) are present, however using GPS logs and this data in
combination should make it possible to map quite a few roads in Denmark.

Is Openstreemap capable of using such data (probably not?) and if not,
what would it take to implement this (I am a developer, but I have no
knowledge of openstreetmap)?

Another question: Is it possible to add properties to roads in the editor?

Best regards Preben
