OpenStreetMap import

Work in progress This article or section will be worked on in the upcoming hours or days. See history for the latest developments.

With the upcoming license change, we'll be able to use OpenStreetMap data in the official FlightGear scenery. Some of the most interesting things to import from OpenStreetMap are shared objects (generic models like windturbines, power lines, water towers).

This article lists open questions, ideas and planes related to the import process.

Object types

This table lists models from the FlightGear scenery database, together with a corresponding OSM tag.

	Tag	Model	Number of objects
Chimneys	man_made=chimney	Models/Industrial/generic_chimney_01.xml	6,486
Lighthouse	man_made=lighthouse	Models/Misc/generic-lighthouse.xml	5,148
Power pylons	power=tower	Models/Power/generic_pylon_*.ac	2,760,804

Questions/problems

• Should we remove shared objects that are currently in the database, if they are not present in OpenStreetMap?
• In order to prevent us from adding duplicates, a certain radius around the (OSM) object location should be checked for the presence of objects. What would be a good radius?
