Render Request
by Thomas Ineichen 20 Aug '10

20 Aug '10

Hi, I put a little work in my access map and created some new styles for quality assurance. I tried to keep it as simple as possible, so the drawing scheme is down to six colours and two line types: http://access.t-i.ch/qa-map.html Each of the different (most important) means of transport has its own layer in which *only* explicit acces-Keys (e.g. bicycle=*) are rendered. The second map uses inheritance according to the following tree: http://wiki.openstreetmap.org/w/images/3/3b/Access_hierarchy_simple.png http://access.t-i.ch/qai-map.html AFAIK it's the first map to draw, what routing algorithms already should rely on. I belive that this map will increase the quality of routing information in OSM and therefore enhance OSM a lot. Unfortunately, the result is 17 different styles, but they should not change much in the future. (Hopefully, they don't change at all!) :) The Styles for the first map are: /home/ti/styles/qa/qa-access.xml /home/ti/styles/qa/qa-foot.xml /home/ti/styles/qa/qa-horse.xml /home/ti/styles/qa/qa-vehicle.xml /home/ti/styles/qa/qa-bicycle.xml /home/ti/styles/qa/qa-motor_vehicle.xml /home/ti/styles/qa/qa-motorcycle.xml /home/ti/styles/qa/qa-motorcar.xml /home/ti/styles/qa/qa-hgv.xml The styles for the second map are: /home/ti/styles/qai/qai-foot.xml /home/ti/styles/qai/qai-horse.xml /home/ti/styles/qai/qai-vehicle.xml /home/ti/styles/qai/qai-bicycle.xml /home/ti/styles/qai/qai-motor_vehicle.xml /home/ti/styles/qai/qai-motorcycle.xml /home/ti/styles/qai/qai-motorcar.xml /home/ti/styles/qai/qai-hgv.xml @Peter: I have deleted the old access.xml and bicycle.xml because they are integrated into this new structure. I don't know yet if there will be other *_combined-styles; for the moment bicycle_combined is unchanged. As soon as the styles are rendered, I will post it on the international list. Thanks again, Thomas

Accessing JOSM from web pages
by Stephan Knauss 29 Jul '10

29 Jul '10

Hi, could be interesting for someone on this list as well. I extended JOSM RemoteControl to provide protocol version information. Besides the possibility for clients to choose a compatible command set this enables web pages to query for a running JOSM. Because of restrictions due to same origin policy this was not possible with the existing plugin. RemoteControl now implements CORS (simple requests without preflight) as well as jsonp for the version check. I implemented a live demo on the cuisine map. In the upper right corner will be an edit button in case a running RemoteCotnrol is detected. http://toolserver.org/~stephankn/cuisine/ The new API command is documented on the wiki: http://wiki.openstreetmap.org/wiki/JOSM/Plugins/RemoteControl Stephan

Tiles are not cached long enough
by Kay Drangmeister 27 Jul '10

27 Jul '10

Hi. I run a mod_tile/tirex/own-renderer system at home. Since my own-renderer is slow I am interested that the tiles are cached indefinitely. I upped the defaults in mod_tile by a factor of 100, so they should be cached 100 weeks or at least 100 days. But they get re-rendered all over again, and I do not know why. Is there a definite log that tells my why mod_tile thinks they are expired? Or is there a system that marks them as dirty (without my knowledge)? Thanks Kay

The Dirtyer - a tile renewer
by Thomas Ineichen 24 Jul '10

24 Jul '10

Hi, as a by-product, I created 'The Dirtyer': http://toolserver.org/~ti/dirtyer/ Paste any toolserver-tile-URL (e.g. tiles/bicycle/13/4290/2868.png) and it will mark the tile itself and up to three generations of offsprings as dirty (where one generation is the four tiles for the same area on the next zoom level). So if OSM data changes, you don't have to request a redraw for every tile yourself. I restricted the maximum depth to 3, so server usage shouldn't be too high. Regards, Thomas PS: What I'm not sure about: Is the tile redrawn immediately when it's marked as /dirty or only with the next request?

Base-Layers
by Thomas Ineichen 22 Jul '10

22 Jul '10

Hi, some time ago, I discused with Kay ( http://parking.openstreetmap.de/ ) that it would be nice to have some kind of rendered base layer without streets. That would give the overlay-creators much more flexibility to design maps. Right now, it is for example impossible to un-highlight the prominent rendering of motorways which are less important for bicycle maps. We did not yet discuss which elements should always be rendered, but I think for a start that would be landuse=, natural=, building=... Any coments, why that would be a good/bad idea? :) Regards, Thomas

I've been unfaithful again ...
by Thomas Ineichen 19 Jul '10

19 Jul '10

... while I was waiting for my tiles to get rendered[1] and created another map that has nothing to do with the original purpose I signed up for: I present you `The WheelChairMap´: http://toolserver.org/~ti/wcm/ It's far from being finished but now ready for a beta-release. (And right now only available in German.) Feedback is very much appreciated. Regards, Thomas [1] http://lists.wikimedia.org/pipermail/maps-l/2010-June/000706.html

It's running, the config was just referring to style files that had been removed since the last restart.

Recent renderd/mod_tile improvements
by Colin Marquardt 08 Jul '10

08 Jul '10

Hi, just today, jburgess improved the renderd output to show which layer is failing (and apparently doesn't exit renderd at this point), and a related mod_tile change ("it now drops any tile requests for the broken layer and logs another error message for each request"). Since I just restarted renderd for a change in hikebike only to see it crash after a few minutes (which doesn't seem to be due to my style changes), these improvements would be quite handy to have. Cheers Colin

monitoring of ptolemy
by Tim Alder 04 Jul '10

04 Jul '10

Hello, is there a way to monitoring the load and the replag on ptolemy? (mumin or so) We get a lots of request[1] from the smoking-map because it was on heise.de[2] but we seems to survive without problems. Greetings Kolossos [1] http://toolserver.org/~daniel/stats/usage_201007.html [2] http://www.heise.de/newsticker/meldung/Raucher-und-Nichtraucherlokale-in-Op…
