Hi Lambertus, hi Thorsten,
that would be great if you can install such a service!
Attached you find a simple bash script to create the bounds file. I must
admit that I couldn't test it because I have only a Windows PC. But I am
sure you find the message in it :-)
I think the -Xmx8g can be a little bit lower if that matters for you. If
you need a much lower value the planet need to be split. Just let me
know. I can send you some poly files with an appropriate split.
Regarding the sea files: I can post a similar shell script within the
next days. But that's also not a big trick:
* Install mkgmap including the extra jar files (the ones in lib/optional)
* Download the new data (land polygons) from openstreetmapdata.com
* Unzip the file
* java -cp mkgmap.jar:<extra libs>
uk.me.parabola.mkgmap.sea.optional.PrecompSeaGenerator land_polygons.shp
WGS84 sea
* Zip the new directory sea containing the new sea files.
Please post a link if you have installed your service so that we can
link to it.
Thanks!

Hi WanMil, all,
'My' servers have enough memory, cpu cycles, storage and bandwidth to
host these files. Can you email me with some details, e.g. the shell
scripts you're using?

Anyhow is there anybody who has some server capacity and is able to
update the bounds and sea files regularly?
For the bounds you need:
A planet file (o5m format requires around 33GB)
The osmfilter/osmupdate/osmconvert toolchain
mkgmap
Additional download of 50-60MB / day to update the planet file
Around 8GB main memory (less is possible but requires some more steps
- I am using 3GB and therefore have to split the planet file into 3
regions)
Some CPU power
For the sea files you need:
Download of 350GB per update
Some CPU power
I can help to create a tool chain which creates these files.

Is it not better to put the boundary and sea files on
http://www.mkgmap.org.uk/download/mkgmap.html (at least a link)?
