Hi Jörn, do you know a source for the names? The input for mkgmap which is used to generate the precompiled data doesn't contain the names. I guess it would be possible to implement an algo similar to that for the geonames-file option in splitter. Or do you think that OSM contains the info?

Hi developers, I use the precompiled sea tiles http://osm2.pleiades.uni-wuppertal.de/sea/latest/sea.zip as mentioned on the mkgmap download site. Unfortunately the tiles do *not* contain names. How can I add the names (at least in English, local languages would be nice) to my maps? And no, precompiling on my own isn't the answer I'm looking for ;-) Thanks for your ideas, Joern
