Re: [Tagging] area=yes on polygones (was Block names)
The german article still has the recommendation of adding area=yes. One of the biggest problems in the wiki is the fact, that very often articles in different languages are not really translations, but different articles. As the tag railway=platform is applicable to areas as well, according to articles in all languages, and therefore area=yes shouldn't be necessary on closed ways, I will update this note in the german article in accordance with the updated english article.

[Tagging] OSMI layers in JOSM
Hi all! I'm trying to view the OSMI layers in JOSM. The all-knowing, all-seeing trash heap pointed me to this (german) article: http://forum.openstreetmap.org/viewtopic.php?id=9315 There it is recommended to use the following link in JOSM: http://tools.geofabrik.de/osmi/view/routing/wxs?REQUEST=GetMapSERVICE=wmsVERSION=1.1.1FORMAT=image/pngSRS=EPSG:4326STYLES=LAYERS=unconnected_minor1,unconnected_minor2,unconnected_minor5,unconnected_major1,unconnected_major2,unconnected_major5; This works like a charm, but with the limitations, that one has to adjust the resolution manually. Also I seem to be unable to get this layer transparent. In the article one wrote to add TRANSPARENT=TRUE to the link, but I can't get this working. Has anyone a hint for me how to get this layer transparent? Is there any possibility to autoadjust the resolution?

Re: [Tagging] area=yes on polygones (was Block names)
miau. OSM does not have area object, thus it needs something to mark object as polygon. There are some tags that insist that a line/relation is filled inside. These are area=yes and type=multipolygon. All the other tags may mean either line or a polygon depending on context. Sometimes context isn't clear. (Is a circular highway a roundabout or a filled square?..) It is rather distinct that highway=*, railway=* are linear usually, and that landuse=*, amenity=*, shop=*, natural=*, area:highway=* are polygonal. However, there are some cases when it's not true, like the platform. We either need a complete machine-readable list of tags that are polygons or lines, or need to tag each object separately. For now I see just the second approach being used; telling that is't invalid without providing any reasonable fallback is a bad idea.

If you draw a closed polygon with railway=platform, that's a continuous platform with a hole in the middle.

No. Most of the polygons do not require a tag area (amenity, building, landuse, leisure, landuse). There are some tags that insist that a line/relation is filled inside. These are area=yes and type=multipolygon. Sorry, I don't understand what you try to say here. type=multipolygon is about relations or I miss something ? Sometimes context isn't clear. (Is a circular highway a roundabout or a filled square?..) Agree. This case is why the tag area has been created. It is rather distinct that highway=*, railway=* are linear usually, Hmm... railway yes, platform not sure. As many other features, platform can be represented by a node, a line or a polygon. This just depends on the contributor and his mapping level (and source accuracy and/or motivation). Same issue with people symbolizing rivers with a line and others with a polygon (and a centre line). We either need a complete machine-readable list of tags that are polygons or lines, or need to tag each object separately. For now I see just the second approach being used; telling that is't invalid without providing any reasonable fallback is a bad idea. Currently used list can be found at http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/default.style A closed loop tagged highway requires an additional information. Until a new element type polygon is created in the futur, the area=yes makes sens here. But a closed loop for railway=platform does not require any thing more than the geometry (a closed way tagged railway=platform is always a polygon. Are you asking contributors to specially tag an object just to avoid some work in osm2pgsql (detect if the way tagged railway=platform is closed or not) ?

If you consider to describe just the block area - just the perimeter - to name it, I think place=locality on a closed polygon would be sufficient.

Re: [Tagging] OSMI layers in JOSM
To make it transparent, you can use one of the buttons under the JOSM layer pane. The pane, by default in the upper right corner, where you can move layers up and down etc. I don't have a clue about the resolution.
