Hello,

background:
for realtime-rendering Traveling Salesman
(http://travelingsales.sourceforge.net)
generated 3 additional,simplified maps when importing a map.
As for obvious reasons residential streets are not a part of
the lower zoom levels (whole city, state, country/continent)
cities are often only empty spaces that motorways go around.

issue:
Where they are missing, I would like to generated landuse=residential
automatically in these places by evaluating the strongly connected
graphs of residential-streets.
Where such polygons have been created by mappers they will be used
instead but there are too few of them to rely on them to be present.

question:
Dies anyone have a good idea for an algorithm that could do this?

Regards,
Marcus
