[09:24:51] <mvglasow> jkoan not really, about splitting the main issue is the way we place objects into tiles:
[09:25:24] <mvglasow> first we split the Mercator map into 2x2 tiles, then split each tile in the same way, a few levels deep
[09:25:41] <mvglasow> and each object must fit entirely into one tile
[09:26:24] <mvglasow> also, there is a minimum depth for some objects (e.g. motorways cannot be lower than a certain tile level)
[09:27:25] <mvglasow> but it means the topmost level will contain a bunch of objects from e.g. London, as they happen to cross the zero meridian
[09:27:45] <mvglasow> even if that's just a driveway or a short piece of hedge
[09:28:58] <mvglasow> so if we process the whole world into tiles and then serve only those needed for the requested area, even folks in Australia will get a few pieces of London in their maps
[09:30:27] <mvglasow> presumably the Planet Extractor has had this side effect all the time
[09:31:11] <mvglasow> we could work on Planet extracts and process those into maps
[09:31:45] <mvglasow> but we'd want to minimize inconsistencies, thus I would at the most do one extract per landmass
[09:32:06] <mvglasow> though that also means Eurasia gets pretty huge
[09:32:32] <mvglasow> basically we have two options:
[09:33:15] <mvglasow> option one: process the whole planet into a binfile, and strip it down on request (at the expense of having a few superfluous objects on the other side of the globe)
[09:33:40] <mvglasow> option two: keep raw OSM data on the server and extract and convert upon request
[09:33:59] <mvglasow> the latter would give us smaller maps but might also involve more processing, as every map is hand-crafted
[09:34:40] <mvglasow> I suspect that, one way or the other, this is going to be a resource-hungry operation
[09:35:45] <mvglasow> do we know who runs the current planet extractor? any way to contact these folks? maybe they're willing to hand over the server, they'd also be able to tell us what it costs to run it
[09:37:27] <mvglasow> maybe they are also willing to release their code... I doubt they have any commercial interest in it, they just never bothered to release it
[09:38:44] <mvglasow> do you think kazer might know? I can try to get hold of him

[12:48:17] <jkoan> mvglasow: having kazer back at least for some time would be great, then he could fix the mapserver in the first place while we are working on the replacement

[12:50:01] <jkoan> for you option one: my question was targeted to this, but solving the problem "process the whole planet into a binfile" as this takes about 4-6 days on my nvme-ssd with ryzen cpu, so way to long for daily updates
[12:51:34] <jkoan> andr the current planet extractor was written by someone not active on navit in a long time. Thats also the reason only kazer may access the map-servers. He wouldn't give me access because of the propatery map server code thats running there

[17:23:39] <mvglasow> jkoan I tried to reach kazer, two out of three known e-mail addresses failed, the third is his own domain (and the domain still exists), let's see what happens
