Hi all,

I have a problem with area of National Park Rila in Bulgaria. There is a limit of 2000 points for upload to OSM and i can't upload all area of park. I separate the area to 3 parts and create relation in multipolygon but in the render still i have 3 separate areas for NP Rila.

Please can anybody help me to visualize one area like National Park Pirin:

I use JOSM to simplify the area but i still have about 5000 points. Another simplification will bring lose of accuracy.

There are two intersecting relations here: the Rila NP ( and a forest area 8 named Рила...

Yes it is. First relation is connected with area of Nature Park, second with forest areas in Bulgaria. Is this a problem?

For relation this is not a final version.

You had three single closed ways in the NP relation (1417776) - I've split them into 3 non-closed ways and now it shows as one area.

But you should split the three ways even more into chunks of maybe 200-node ways because it is a pain do edit an area in for example potlatch with such long ways having to load first where only a small part of that way is viewable in the current edit area...

We have some similar problems for other NP in Bulgaria. For type of relation we use boundary and this makes problems with mapnik render. I will change relation=multipolygon like you.

Thank you very much katpatuka

BTW: it's enough to tag the relation itself with type=multipolygon, boundary=national_park and name=... - the single ways may only need a source=bing|landsat|yahoo... ;-)

There are still tools that do not support multipolygons yet so keep the tags.
