Balaton (Plattensee) drawing error

[tds4u]

Hello, all water areas, like Bodensee or Müritz, are drawn. But the Balaton (german Plattensee) isn't. In JOSM it is drawn, in Mapnik too. But MapServer itself don't. Is there a problem in converting polygons or lines (tested with both - no success)?

Is there a problem in the polygon or not? Please help :-)

Is the geometry missing in all waterareas tables or only the _genX. Do you have an OSM ID of the geometry?

[tds4u]

Okay, here we are :-)

SELECT "id","osm_id","name","type","area","geometry" FROM "public"."osm_waterareas" WHERE "name" LIKE 'Plattensee'

310438 => 26735206 3995998 => 168361423

SELECT "osm_id","geometry","name","type","area" FROM "public"."osm_waterareas_gen1" WHERE "name" LIKE 'Plattensee'

26735206 168361423

Data in gen0 not found (too small).

And these are the geometries that are not rendered? You can check the IDs on OSM: http://www.openstreetmap.org/way/12345 or http://www.openstreetmap.org/relation/12345

Can you check if the geometries make sense (ST_IsValid, ST_IsSimple, ST_Area)?

Ah, sorry, searched wrong name (Plattensee instead of Balaton). Right ist http://www.openstreetmap.org/relation/1638031 = reservoir. But still not displayed.

=> Should be correct

SELECT "id","osm_id","name","type","area","geometry", ST_AsText(geometry) FROM "public"."osm_waterareas" WHERE "name" = 'Balaton'

=> Polygon from WMS BoundingBox => no visible Balaton as name

SELECT "osm_id","name","type","area","geometry" FROM "public"."osm_waterareas_gen1" WHERE ST_Intersects(ST_GeomFromText('POLYGON(( 1956787.9268898 5948635.2920548, 1956787.9268898 5909499.5335728, 1995923.6853718 5909499.5335728, 1956787.9268898 5909499.5335728, 1956787.9268898 5948635.2920548 ))', '3857'), geometry) ORDER BY name

Is there a mistake or why no correct results returned? Small basins inside are there but not the big one.

Ok, the relation is broken. See: http://analyser.openstreetmap.fr/cgi-bin/index.py?relation=1638031 The end node 2607089288 of way http://www.openstreetmap.org/way/232147389 is not connected.

Not sure what magic osm2pgsql does do get a geometry out of that.

Have to say that the same problem is on other geometries, too. Like natural polygons (forrest, etc.). Fix should be important.
