Hello, I have s-57 data locally on my pc. It would be good if There was a Way to transform them into OpenSeaMap files. I am trying to use JOSM. But it only seems to use files from server and only use s-57 data for the backend. Is There a way or tool to transform s-57 data to osm files? thanks for your help. asked 25 Oct '16, 13:24  bhoelzemer |
One Answer:
so I found out that there is a S-57 Java Suite with the capability to transform the data from S-57 to .osm but I didn't find any docu on how to use it:( answered 08 Nov '16, 09:04 bhoelzemer The S-57 Java Suite at wiki.opennauticalchart.org? The wiki page mentions a tool named This tool is also located in the JOSM plugins github repository. So maybe you can just install this seachart/js57toosm JOSM plugin to convert your file.

JOSM can open a number of formats, besides the "native" osm format via it's OpenData plugin. I do not believe s-57 is between those formats. I also do not understand why you think JOSM can do anything with s-57 files.
Furthermore, what are OpenSeeMap-files ? AFAIK OpenSeaMap is a website displaying maps. According to this [posting on gis.stackexchange](http://gis.stackexchange.com/questions/60884/how-to-open-the-electronic-nautical-chart-s-57-data] QGIS can open that format.
Thank you for your quick answer. So if I understand correctly JOSM has nothing to do with ENC s-57 data?
Absolutely non, JOSM is just a generic editor for OpenStreetMap data in general. There might be plugins dedicated to nautical chart data, or presets for nautical tagging, but that doesn't make it a nautical chart editor. The fact that the OpenStreetMap database contains some nautical data, primarily initiated through the OpenSeaMap project, also doesn't make it a nautical database. By the way: you are sure you are allowed to upload your S-57 data to OSM. Isn't it licensed somehow, and possibly incompatible with the OpenStreetMap license and sharing policies?
