Hi all, validator would not find ways like these two: https://www.openstreetmap.org/changeset/64081765
They are in the middle of South America. I found them only because they visually stuck out in JOSM. I would not find such an island when it is close to the real coastline but on land.

What is it that makes the correction so complicated? My approach would be this: 1) download planet 2) filter ways with natural=coastline 3) split the file with splitter into e.g. 100 parts 4) for each part: - open in JOSM - run validator - If an error is found, download that area to have current data and fix it This should allow to find and correct unconnected coastline ways within a few hours. Am I missing something? Gerd ________________________________________ Von: mkgmap-dev <[email protected]> im Auftrag von Thorsten Kukuk <[email protected]> Gesendet: Donnerstag, 1.

Not really, as he writes on his web page, his tools tries to repair the coastlines. And as I use them, too, I know that this automatic "repair" can break the result even more. I have added some additional post-precessing checks and patched osmcoastline to bail out on more errors to make sure that the result is for me really useable. Currently the coastlines are so heavy broken, that osmcoastline only seg.faults. So there will be no update with the broken costlines. I assume that why geofabrik does not report coastlines errors anymore, too.
