[OSM-talk] Advanced relationships

[Peter Miller]

I have been immersing myself in the GDF standard for the last couple of
weeks and see it as offering solutions to a number of pressing OSM issues,
including restricted manoeuvres.

At Frederick's suggestion I have just completed a rework of the GDF wiki
page and would appreciate some feedback. Please check it out here:

In summary: 

GDF is a standard that offers ready made solutions to many of OSM's current
concerns (and other likely future concerns).

Restricted Manoeuvers: The model has an elegant way of describing restricted
(or prohibited) manoeuvres.

Lane Dependent Attributes: It is possibly to apply different attributes to
different lanes on a road.

Street Furniture: It is possible to associate features (such as letter
boxes, bus stops, buildings) along a Road Element by saying 'feature X is Y
meters along the Road Element R, offset Z meters to the Left/right'

'Super Ways': Aggregated Ways are used to describe larger features (such as
motorway), something which regularly gets aired on the OSM mailing list.

Construction Status: any feature can be marked as 'planned' or
'under-construction'.

Complex Bridges etc: A way of defining a single bridge/tunnel/viaduct that
is used by more than traffic crossing.

Enclosed Traffic Area: An area which can be used for unstructured traffic
movements (a large square for un-structured vehicle movements, or a park for
unstructured pedestrian movement)
