Your precompiled sea data is from mid of december, the changes to the coastline in that area where made yesterday. You need to create your own precompiled coastline data from the current OSM database.

I see. Thank you. But according to this http://wiki.openstreetmap.org/wiki/Mkgmap/help/options#generating_precompile d_sea_yourself and this http://openstreetmapdata.com/data/land-polygons it is quite complicated to make your own precompiled coastline. So I will have to wait for an update of the ready made coastline.

Creating them is really simple, but getting the tools installed and running isn't trivial :( If you use a 64bit Linux system, I can give you a pointer to my RPMs for this.

Can precompiled sea be created fully automatically, or is it necessary to tweak broken coastlines manually? I have access to a system running Red Hat Linux 64 bit. But I have no root access and there is not much installed on the system, only java. And I have not much experience using Linux. But it may be worth a try. If the process can be made fully automatic, I could provide precompiled sea on a regular schedule.

See http://wiki.openstreetmap.org/wiki/Mkgmap/help/options#Using_precompiled_sea I think the process depends on the coastline data from http://openstreetmapdata.com/data/land-polygons So, it makes no sense to produce data on a daily bases when the input data is updated less frequently (current data is from 2013-01-03.

You can create the land polygons on your own, doesn't take much more time then downloading them. If you get libgdal correct installed and running for use by osmcoastline. That was the tricky part, since you cannot use the current code from all projects, they will not work together. You need to fetch the right releases.

If there are no errors in the coastlines, it can be done fully automatically. If there are errors, you have to fix them first in the OSM database and retry the process.

You need to install quite sime C, C++ and java libraries and binaries. So without root access, it will be difficult, because you have to recompile everything and install it in your home directory. The process is in short: - get current planet file or update your local copy - osmcoastline -i -f -p land -o coastline.db planetfile.osm.pbf (if return value is 0 or 1, continue, else abort and fix the errors first) - ogr2ogr -f "ESRI Shapefile" land_polygons.shp coastline.db land_polygons - mkgmap_sea_generator land_polygons.shp WGS84 sea-$NEXT (mkgmap_sea_generator is a script calling the mkgmap java function) sea-$NEXT contains now the new precomp sea data. This tooks about 1-1.5 hours, depending on your machine.

I was playing around with ogr2ogr (and ogr2osm) on my Windows machine a while ago. So I know how complicated and time consuming it is to set up gdal based things. Providing precompiled sea might be a task for someone who is more familiar with this. Is http://www.navmaps.eu/wanmil/ the only source available for precompiled sea or does someone have a more recent one?

AFAIK the data on http://openstreetmapdata.com/data/land-polygons is updated daily - but only if there are no severe problems. The data is created with osmcoastline too. So I guess it is enough to have a check skript if the data is updated. WanMil

Yes, the land-polygon shape files are recent now. So I want to use them instead of messing around with gdal. Where can I find the mkgmap_sea_generator script and how are the libraries to setup? I am not familiar with mkgmap Java sources.

You have to compile mkgmap with the SeaGenerator. I think these are the mimimal steps: 1) if you don't have the sources, get them via svn or download the tarball : http://www.mkgmap.org.uk/download/mkgmap-r2464-src.tar.gz 2) install the java compiler, see http://www.mkgmap.org.uk/develop.html and do what is described under "Minimum requirements", 3) to compile mkgmap with the PrecompSeaGeneraor change the build.xml: search for a line like this: <exclude name="**/optional/*.java"/> and replace it with <exclude name="**/dem/optional/*.java"/> Without this change, some required classes are not compiled. 2) execeute ant resolve-optional to download the needed jar files 3) download latest splitter from http://www.mkgmap.org.uk/download/splitter.html, unzip, and and copy splitter.jar and \lib\fastuitl.jar to mkgmap\lib\optional 4) execute ant 5) chdir to mkgmap\dist 6) execute mkgmap with a command similar to this: D:\mkgmap\dist>java -Xmx5000m -cp mkgmap.jar;..\lib\optional\* uk.me.parabola.mkgmap.sea.optional.PrecompSeaGenerator f:\osm\land-polygons-split-4326\land_polygons.shp WGS84 e:\sea Hope that helps?

Thank you, this helps a lot. I was trying it on my Windows machine with good success. At the moment step 6 is running. What difference does it make to download the split polygons instead of complete polygons? I am also trying to get it running on a Linux server. It was fine up to step 5.

That means that you probably have compiled the files with Java 7 and now you try to start it with Java < 7.
This did the trick. Thanks a lot. It is interesting that it works well with jdk7 under Windows, but for Linux jdk6 is needed. My precompiled sea can be downloaded here: ftp://ftp5.gwdg.de/pub/misc/openstreetmap/openseamap/garmin/osm_precompiled_ sea.zip It will be updated at least on the 2nd and 17th of each month.

What difference does it make to download the split polygons instead of complete polygons?
Processing complete polygons require *much* more memory and I guess it needs a lot of more time to process them. The reason is that there is one *very* big polygons for europe, asia and afrika. And the PrecompSeaGenerator has to split that very complex polygon into several small pieces. So it is easier to process already split and therefore smaller and less complex polygons. WanMil
Alternatively, you can use my coastline extracts: http://fabianowski.eu/osm/coastlines/ They are not precompiled coastline files but coastlines extracted from the planet file and the Geofabrik Europe file. You can feed them to mkgmap directly. I update the files as time permits. The most recent one is dated 20th January 2013 at this moment. - Bartosz
