Shape extraction for Wikipedia articles
by Bernhard W. 29 Sep '11

29 Sep '11

Hi all! I'd like to continue with the Shape extraction for Wikipedia articles, like Kolossos has begun with the http://wiki.openstreetmap.org/wiki/Query-to-map Query-to-Map-project. There is pretty much already there, even the complete endresult, like I mentioned in https://wiki.toolserver.org/view/GeoShape#Frontend_Examples What I'm thinking about is: I don't think the Osm2pgsql database schema which we have (I think) is suitable for the long-term for the reasons mentioned in the same article further below, https://wiki.toolserver.org/view/GeoShape#Comparasion_osm2pgsql_and_osmosis mainly because I cant find a good changemanagement for derivate tables, which can be worked around maybe or which can be omitted creating a new Shape table every now and then. Personally I like the lonvia approach best, it's a Osmosis snapshot schema which is quite up to date to my opinion and its a ready GPL package. On the other hand, it's in phyton which may not be 'everybodys darling' [PK], and it's rendering functions are not needed for this purpose here. In one thing I tend to agree with Stephan Plepelits: Unfortunately we have to import the database twice ... once with osm2pgsql to have a database structure which is usable for mapnik. A second time with osmosis, because we want to have all possibly available data. http://gitorious.org/openstreetbrowser/openstreetbrowser/blobs/master/DOCU What do you think? Guverneu/Bernhard

Cannot "dirty" some tiles
by Kay Drangmeister 27 Sep '11

27 Sep '11

Hi, While it is generally possible to "dirty" some tiles on toolserver, I tried with this one: http://toolserver.org/tiles/parking-bw/4/8/5.png (i.e. appended /dirty to it), but reading the .../status, it always says: Tile is clean. Last rendered at Sun Jul 24 03:47:23 2011 How can that be? It must always be possible to manually request a rerender. What is the difference between tiles that can be dirtyfied and this one? Kind regards, Kay

Update of Openlayers to 2.11
by Tim Alder 21 Sep '11

21 Sep '11

Hello, I updated /osm/libs/openlayers/latest to 2.11. Now OpenLayers supports mobile multitouch devices! Some optimisation in our code seems necessary to run fast, like: http://openlayers.org/dev/examples/mobile.html or http://www.openstreetmap.org Perhaps somebody want to play with it. Thanks to OpenLayers! Greetings Kolossos

Hi could someone (Peter) please update my parking styles on ptolemy? I'd do it myself, but https://jira.toolserver.org/browse/TS-1107 is still unresolved. The styles are here: /home/kayd/deploy Samples are here: /home/kayd/map-*.png Thanks, Kay

Possible tirex render queue bug?
by Kay Drangmeister 16 Sep '11

16 Sep '11

Hi. I noticed that a lot has been done re-organizing the rendering queues on the toolserver. YAY! http://munin.toolserver.org/OSM/ptolemy/tirex_status_queued_requests.html looks now very colorful - mostly green (background). Thanks to everyone working on this. Many of the tiles I waited for have been rendered now. However - there seems to be some buggish behaviour: looking at http://toolserver.org/~mazder/tirex-status/?short=1&extended=0&refresh=0 it currently shows: Tirex Master Status (updated=2011-09-16 15:33:12) Master server: started=2011-09-11 06:28:53 pid=4623 Queue: Prio Size Maxsize Age 1 0 427 2 65 181 0:01-1:20 <- *** Size increasing *** 10 3025 3614 7742:24-7647:13 <- *** Size decreasing *** 99 50149 50149 1:26-7744:02 all 53239 53323 0:01-7744:02 Buckets: (load=3.75) Name Priority Rendering MaxRend Maxload Active Can Queued Age missing 1- 1 1 6 20 yes yes 0 systema 2- 2 4 5 8 yes no 65 0:01-1:20 dirty 3- 9 0 4 8 yes no 0 bulk 10- 19 0 6 6 yes yes 3025 7742:24-7647:13 background 20- 0 3 4 yes no 50149 1:26-7744:02 Currently rendering: (num=5) Map X Y Z Prio Age default 164568 85216 18 1 1 hikebike 33904 22840 16 2 6 hikebike 33912 22840 16 2 4 default 4224 2856 13 2 3 default 8448 5712 14 2 2 From what I see, queue systema (prio 2) is filled (65) and rendering. But when I refresh the page, I can see that the "bulk" queue Size is decreasing. So tirex must (realy?) be rendering Prio 10 tiles as well, but it's never showing in the "Currently rendering" table, there I can see only Prio 1 and 2 tiles. How is this possible? Kind regards, Kay

Starting of re-rendering all tiles
by Tim Alder 12 Sep '11

12 Sep '11

Hello, we haved now reached with the re-rendering the point z-curve=0.25. So we are now rendering the emptiness of north norway. But this has no visible effect on the rendering speed. The rendering performance correlate very good with the queue length. I found now the parameter -num in tirex-batch to limit the queue length. I will restart the process for tiles with z>0.25 and limit the queue to a value of around 5.000. "vacuum full" is now running more than 1 day. If it's not done tomorrow, I believe I will stop it. Ok? Greetings Kolossos

replag is growing /no contact to planet.osm.org
by Tim Alder 09 Sep '11

09 Sep '11

Hello, maintenance on OSM.org is now over but our replag of ptolemy is still growing. We are not able to contact the diff-server from OpenStreetMap: osm@ptolemy:~$ ping planet.openstreetmap.org no answer from planet.openstreetmap.org Ping works fine from nightshade or my laptop. I hope nobody block us. We change nothing on the config. Greetings Kolossos

It seems to work at beginning. The load-next script had the expire.rb script enabled which is the wrong method of expiring. The correct one follows some lines after the expire.rb statement. I commented out the bad commands. I also lowered the maxInterval setting from 24h to 6h, so we can check sooner if this fixed the problem.

Peter wrote a little tool to show the replag: http://toolserver.org/~mazder/tirex-replag/?refresh=0&human=1 So we have now a replag of 4 days and I would say we need 3 days to be up-to-date. Unfortunately is munin-graph again out of order: http://munin.toolserver.org/OSM/ptolemy/replication_delay2.html and jira-request TS-1125 after nearly a month still untouched. :-( I believe it would be difficult for us to keep the wiki up-to-data, so let's use this list.

I start to rendering all tiles z=9-18 systematically, that are watched in the last 64 days and older than 3 days (because expire didn't work a long time). I put additional z=16-18 in the batch because it is else difficult to handle in different processes. We rendering 150-200 tiles/min what is really nice. There are 3 Mio. tiles in the batch so it will need around 11 days. After this we need to re-render only tiles that are older than a year because expiring is again working, so there will be than much fewer tiles to handle.

Looks great. http://toolserver.org/~mazder/tirex-status/?short=1&extended=0&refresh=0 shows a new queue "systema", I guess that's exactly it. One observation: currently putting re-rendered tiles into the queue is a bit quicker than the queue rendering tiles, so the queue grows slowly over time. Nothing to worry I guess, tho'.

This can be changed in source [1] (i guess the second int in the array is the priority for cmdRender).

Will this not quickly mess up the systematic ordering of the systema queue? Is it possible to turn off this reordering? Has this got something to do with that throughput has dropped from 160 - 200 down to (still better than before) 60 - 70 tiles / minute? But overall, it does seem the systematicity is working. > >> And is "dirty" now separate from the "systema" queue (as is apparent)? >> If I try to manually dirty a metatile, I don't see it appearing anywhere >> on the page linked above. > > when tirex receives a dirty message from mod_tile (metatile oder then > planet-timestamp), it enqueues it with prio 2, so it's put into the > systema bucket. This can be changed in source [1] (i guess the second > int in the array is the priority for cmdRender). Perhaps the mappings from mod_tile render request types to tirex priority levels could be made configurable. Alternatively, one could tune the mod_tile config to send requests as cmdDirty rather than cmdRender (the latter assumes the request can be rendered on the fly, which isn't the case if about 300k tiles are ahead of it in the queue) mod_tiles cmdDirty maps onto tirex prio level 10 by default.

Hello, my theory is that we started with rendering around Alaska. This area is relative empty and stretched by mercator-projection. Now we are somewhere in Canada/USA incl. NYC with high density of geo-objects. Following the z-curve we should come back to empty areas in the north several times, and render again very fast. If not, my theory is false. In general: Tirex should be able to order the queue by z-curve, especially if you have more than one style (not sure how it can reach the end of it), it would makes it for me much easier to handle it. And Tirex should be able to not order the queue. >> when tirex receives a dirty message from mod_tile (metatile oder then >> planet-timestamp), it enqueues it with prio 2, so it's put into the >> systema bucket. This can be changed in source [1] (i guess the second >> int in the array is the priority for cmdRender). I change the parameter to 4 in ~/tirex/lib/vendor_perl/5.12/Tirex/Source/ModTile.pm It seems that it need a restart of tirex, what I don't want to do in the moment. > > Alternatively, one could tune the mod_tile config to send requests as > cmdDirty rather than cmdRender (the latter assumes the request can be > rendered on the fly, which isn't the case if about 300k tiles are ahead > of it in the queue) mod_tiles cmdDirty maps onto tirex prio level 10 by > default.

There are no blocks from our side, although ping replies are rate limited which may be causing the ping issue.
