| As for the shields this is deviating from the topic at hand but for it
| the shield can be derived from the lookup table on the wiki and then
| extra preprossesing in osm2pgsql to assign a shield based on admin
| polygons + info from the lookup table

If osm2pgsql can be taught to detect in which admin polygon a way is
maybe it can then also notice when a way intersects a building.  Or
any other area.
