The problem is not fixing the occasional problem with coastlines. When I encounter a coastline problem, I recreate that area with much smaller map tiles so I can narrow down the flooded area to a small region. Usually the problem can be found and fixed within an hour. My problem is that people

Yesterday germany had no coastline-problems ;) An easy way for correcting the errors would be the possibility to open the splitted osm-Files. Then you can fix the error direct (and afterwards in osm-database). There is no waiting for next planetfile. Now I draw in Mapsource rectangels of the

Hello, this will crash, if you wont divide planetfile-id-numbers and your own id-numbers. The easiest way would be an negative id-number. But Nops composer doesn't support negative id-numbers. cu, aighes -- View this message in context:

No, I'm fixing norwegian coastline. Typical errors are fake lakes next to the coastline or lakes tagged as natural=coastline and not as natural=water. cu, aighes -- View this message in context: http://gis.638310.n2.nabble.com/Maintaining-generated-sea-polygons-tp5082865p5098599.html Sent from

Hi, I have found out that in my case it was not caused by the splitter, but a mistake in osm: a coastline placed on top of another one. I removed the last one and now it renders fine. Werner wrote: I used splitter and mkgmap to compile a map of Finland, based on geofabrik- data. The map was
