I'd like to make a proposal for improving [EMAIL PROTECTED] Before anyone asks, yes, I am volunteering to code this. I'm looking for clarification, feedback, or suggestions.
Sorry Sebastian and I got a bit thin-skinned but the amount of well meant but resource consuming suggestions was a bit much over the last days/weeks. Thanks anyway for really wanting to contribute.
And also thanks for taking *your* time to try and understand how it works currently, and explain exactly what you want to do, how you perceive the problem, why and how you think it should be solved. This makes it real fun to answer your questions.
The problem with this is that this data is distributed as part of the code. The file can be updated and recommitted to svn, but areas will be rendered incorrectly until every [EMAIL PROTECTED] client gets every update.
This is in the process of being fixed, but one dependency less would probably be a good idea, Especially since moving this big binary file in and out of svn probably isn't the most efficient way to do it.
I'm not repeating what Sebastian told you, to keep it short, and save a bit of your time.
It should not affect the performance of close_areas.pl by much, since it only needs to retrieve one tile (or 9 tiles if a miss).
I think it's only 5, the diagonal tiles are not consulted IIRC.
The big advantage of this method is that anyone can fix a tile without needing developer svn access, and without requiring renderers to constantly update their code. It only requires a moderate change to close_areas.pl and the creation of one new layer, and doesn't impact the rest of the process.
There is also the update mechanism via informationfreeway.org at z12, but I am currently not sure who maintains the updating of oceantiles.dat from there.
Another thing: basically close-areas.pl doesn't really need other information than sea/land, because if the tile is coastal, it will know by the coastline entering and leaving the tile. Basically all that's interesting to close-areas.pl is: do we need to make a coastline-way around the tile to render and create islands inside, or do we treat closed coastlines as "lakes"?
