Hi Gerd,
due to your reply I got, that sea areas are defined by a coastline never hold names ( https://wiki.openstreetmap.org/wiki/DE:Gew%C3%A4sser ).
Meanwhile I discovered multipolygons as http://www.openstreetmap.org/relation/7645796 which name sea areas (this is nameless in my outputs, but the part east of the state border has the correct name). I guess, many (all?) my readings of lagoons are realized in that way. My first tries to add a working code to my style failed.
Your idea for a new algo to name at least the main sea areas sounds very good to me. May polygone shapes be a solution to segregate the "parent" sea (e.g. Indian Ocean), "childs" (e.g. Arabian Sea) and the "grand-childs" (e.g. Gulf of Aden)? But how to avoid redundancies with coastlines? It seems to be more challenging than the geonames-file.

[mkgmap-dev] Precompiled sea tiles contain no names - how to add names of sea, lagoons etc?
From Gerd Petermann gpetermann_muenchen at hotmail.com on Tue Nov 28 20:14:19 GMT 2017

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?

Gerd

Betreff: [mkgmap-dev] Precompiled sea tiles contain no names - how to add names of sea, lagoons etc?

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
