[Potlatch-dev] POI features vs area features

[Greg Troxel]

    In map_features.xml atm there appears to be a pretty big distinction
  drawn between "poi" features (notably shops, amenities of various
  kinds) and, for want of a better term, "area" features. They're
  defined in separate parts of the file, they have different kinds of
  icons, different categories (there isn't even a "shopping" category
  for way features)...

I first thought you were talking about mkgmap and converting area
features to nodes for garmin search, and the osm->garmin style rules.
Obviously I was confused, but my reaction is:

  It seems reasonable to say that anything that can be a node that's
  sort of like a POI can also be an area, which means either a closed
  way or a closed way with building=yes or area=yes, with the same tags
  as the node would have had.

  it would be cool if all renderers agreed that this was all equivalent

  maybe closed ways that are proxies for things that are originally
  nodes should have a node=yes tag, and that turns on "treat these tags
  semantically as if they were on a node".   Then we can remove the way
  feature duplicate tagging rules and simplify.

  because in the garmin world we need to map areas to nodes because area
  POIs don't show up in searching, and because it's good to have a node
  being the entrance for large POIS (front door of 3 hectare store), it
  would be really nice to have a clean way to tie a node which is the
  "if you need a point, here it is" location to the polygon, so that all
  users that need a point for an area can get one, and autoconvert the
  centroid if such is not tagged.

  I wonder how different front door node of store polygon and town
  center node of town boundary really are.
