Re: [OSM-talk] strange gaps filled by water at zoomlevel 18
Hello again everybody! I'm continuing exploration about that water bug, and I've found the limit of that effect, which is a huge 200km*2000km rectangle : http://www.openstreetmap.org/?box=yesbbox=81.23549%2C54.060041%2C85.627667%2C68.841992 Some edge pictures are: East http://www.openstreetmap.org/?lat=55.27545lon=85.627667zoom=18layers=M South http://www.openstreetmap.org/?lat=54.08514lon=83.40566zoom=18layers=M West http://www.openstreetmap.org/?lat=58.858448lon=81.23549zoom=18layers=M North http://www.openstreetmap.org/?lat=68.841992lon=82.550755zoom=18layers=M I've found no strange geometry at the edges of the rectangle, and the edges do not always coinside with tiles edges (see this for example: http://b.tile.openstreetmap.org/18/190225/73869.png) So the problem affects not only my city, but a huge 2000x200km area, and I have no idea how to locate the error. Any suggestions here? On Thu, Mar 7, 2013 at 2:17 PM, Pavel Melnikov positro...@gmail.com wrote: Hello fellow osmers!

Re: [OSM-talk] strange gaps filled by water at zoomlevel 18
That's really odd. Looking at the NW corner, I couldn't find any nodes, ways, or multipolygons. It appears to only be broken in Mapnik. The other styles render fine. I'd suggest a bug report - trac.openstreetmap.org Clifford On Sat, Mar 9, 2013 at 7:38 AM, Pavel Melnikov positro...@gmail.com wrote: Hello again everybody!

You can find it with Jochen's coastline tool, but it is not completely improbable that someone already fixed this. In order to have the rendering fixed you should make sure that the coastline shape file on the rendering server gets fixed / changed. cheers, Martin___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] strange gaps filled by water at zoomlevel 18
Hello Martin! Sorry to be that newbie, but what coastline tool are you referring to? If it's osm inspector, then I cannot see anything suspicious going on [1] - no red icons or other errors. Also, Novosibirsk is in the middle of Asia, pretty far from any world coastline shapefile data.
