[OSM-talk] osm2pgsql multipolygon parsing

[Frederik Ramm]

Hi,

> The remaining question is, what should be the correct behavior?

My assumption until now was:

* If a multipolygon is untagged - where "untagged" means that it has no
tags except a small list (type, source, source:*, note) then it will
simply receive *all* tags from all (outer) member ways, but processing
will fail if these tags differ in values.

* If the multipolygon is tagged (with anything except type, source, note
etc) then those are the tags for the polygon and way tags will not be
looked at.

* If the tags of the inner way differ from the tags of the outer way or
the tags of the relation, except source, note etc., then the inner way
will become a separate polygon.

All this was without trying to make a judgement about which tags are
"polygon tags" and which aren't.

Bye
Frederik
