Integrate the coastline algorithm into the mapfile-writer

[mapsforge]

From thilo.mu...@gmail.com on October 14, 2011 18:53:28

We decided to move the generation of closed (water and land) polygons from the map library to the mapfile-writer. We should be able to use our existing Java implementation for that, which is currently located in the android.maps package.

As the coastline algorithm is no longer executed by the map renderer, many water areas and islands will be missing until we have fixed this.

A new, coastline-aware version of the mapfile-writer is now available from git://git.assembla.com/mapsf_coastline.git. For further details, please consult the message ("Request for comments on new coastline-aware mapfile-writer") posted to the mapsforge-dev mailinglist earlier.

Is there anything that stops this integration going forward?

Where could I find the coastline-aware version of the mapfile-writer? I've got many bugs with coasts when I changed my maps from 0.2.4 to 0.3.0 :( It was working quite good before...Hopefully you can give me a solution. I've read something related with coastlines, could I add a coastline to my OSM map?

I'll be very pleased if you could help me in loooking for a problem solution. It's a problem of incorrect water draw on the map posted Oct 14, 2011. Could you please tell me when this defect can be submitted approximately?

There is now a companion project to mapsforge at https://github.com/mapsforge/mapsforge-mapcreator that includes the water areas correctly by implementing an approach that has been discussed on our mailing list. https://groups.google.com/forum/#!searchin/mapsforge-dev/Missing$20water$3A$20a$20work-around$20solution/mapsforge-dev/x54kHlyKiBM/jUK4oRHvHUEJ.

Using an external coast line set is preferable to duplicating this effort in mapsforge, so I am closing this issue.

Thanks Ludwig, I'll check the results.
