| 07:02:41 | seven_: | I know that ur, astroidex and Testbaudson will not be here today. |
| 07:04:06 | mandsch: | hi seven |
| 07:04:35 | mandsch: | ok, holidays or bolsena already ... |
| 07:06:04 | nazgul: | hi... |
| 07:06:15 | nazgul: | quite a number on holiday : ) |
| 07:06:28 | mandsch: | yeah, looks like ... |
| 07:10:16 | seven: | I got active and did some marketing. |
| 07:10:22 | seven: | at least at last... |
| 07:10:34 | seven: | submitted two talks for FOSS4G |
| 07:10:46 | seven: | will give one at GSDI 11 in Rotterdam |
| 07:10:59 | seven: | Workshop for the Greek OSGeo chapter in two weeks |
| 07:11:13 | seven: | and marketing material ( case study ) on prtr. |
| 07:11:46 | seven: | PRTR is not exactly a Mapbender highlight but the whole project is cool. |
| 07:12:00 | mandsch: | what is prtr? |
| 07:12:09 | seven: | http://www.prtr.bund.de |
| 07:12:14 | sigq: | Title: PRTR - Pollutant Release and Transfer Register ( at www.prtr.bund.de ) |
| 07:12:36 | seven: | The first German Federal Administration that uses OSM data |
| 07:12:57 | seven: | the stack is core: PG/PostGIS, MapServer, Mapbender. |
| 07:13:00 | mandsch: | hmm, nice. |
| 07:13:15 | seven: | 36 servers in an ESX cluster serve the OSM WMS. |
| 07:13:19 | seven: | Cool hardware... |
| 07:13:37 | mandsch: | wow! |
| 07:13:38 | seven: | largest install that I have been working on in the past years. |
| 07:13:57 | mandsch: | are you administering the wms server? |
| 07:14:03 | seven: | Yes. |
| 07:14:11 | mandsch: | cool... |
| 07:14:38 | seven: | They need much better cartography, but the raw stuff already works fine. |
| 07:14:52 | mandsch: | just wanted to ask ... |
| 07:15:01 | seven: | The interesting bit is that the OSM data comes right out of the databas. |
| 07:15:05 | mandsch: | have you tested with agg rendering? |
| 07:15:10 | seven: | We had to do a lot of generalization. |
| 07:15:21 | mandsch: | ah, yes yes, it's awful slow ... |
| 07:15:27 | mandsch: | but with 36 servers ... |
| 07:15:34 | seven: | AGG rendering start below 1:40.000 only because images are size *10 |
| 07:15:38 | seven: | slow? |
| 07:15:49 | mandsch: | not this service |
| 07:15:51 | seven: | Ah, the WhereGroup OSM WMS is unsuable... |
| 07:16:00 | mandsch: | but when using the osm data raw from the db ... |
| 07:16:14 | seven: | maps are 36k with GIF / no AGG |
| 07:16:20 | seven: | and up to 500k with PNG and AGG |
| 07:16:41 | seven: | for people with ISDN access that is painful. |
| 07:16:47 | mandsch: | ;- ) |
| 07:16:54 | seven: | We should detect speed and offer two versions. |
| 07:16:56 | mandsch: | we need tiles ... |
| 07:17:11 | seven: | First we need slippy maps. |
| 07:17:23 | mandsch: | ok, that's a nice start ... |
| 07:17:25 | seven: | So that maps stay until the new ones are loaded. |
| 07:17:53 | : | * seven does not like tiling, no reprojection, fixed scale levels. Ugh. |
| 07:18:21 | : | * mandsch neither, but he don't thinks that osm data is made to be served on-the-fly ... |
| 07:18:27 | seven: | Hm. |
| 07:18:36 | seven: | Probably not. |
| 07:18:54 | mandsch: | but i easily convince of the opossite . |
| 07:19:21 | mandsch: | is image size the only thing or also preocessing time with agg? |
| 07:19:25 | seven: | It would be cool to be up to date on a daily basis. |
| 07:19:44 | seven: | interestingly preprocessing with AGG does not make a difference. |
| 07:20:08 | mandsch: | have you tried quantization? |
| 07:20:13 | seven: | We actually just switch formats from GIF to PG. Rest does MapServer. |
| 07:20:29 | seven: | mandsch: What is quantization? |
| 07:20:41 | mandsch: | hmm, not sure if i spelled it correctly ... |
| 07:20:48 | seven: | -> GIF to PNG |
| 07:20:49 | mandsch: | it reduces the colors |
| 07:20:52 | seven: | yes. |
| 07:21:05 | seven: | but it seems that MapServer detects first, |
| 07:21:06 | mandsch: | bit you still have the agg look |
| 07:21:11 | seven: | which format. |
| 07:21:14 | seven: | and then does not use AGG |
| 07:21:26 | mandsch: | not, it won't use agg with gif |
| 07:21:34 | seven: | Exactly. MapServer does not use AGG |
| 07:21:48 | seven: | its not a Bug but it is a Feature. Maybe. |
| 07:22:08 | mandsch: | we'll but it's cool. |
| 07:22:25 | seven: | If we manage to make a daily diff with updated data |
| 07:22:42 | seven: | then it would make a lot of sense that we use WMS and not canned tiles. |
| 07:22:54 | seven: | Always the newest data... |
| 07:23:01 | mandsch: | true ... |
| 07:23:07 | seven: | We want to add a button "Edit now..." |
| 07:23:14 | seven: | that links to OSM / Potlatch |
| 07:23:30 | seven: | so that people can directly hack the map - and see it next day. |
| 07:23:55 | : | * seven dreams on: Add a OSM editor to Mapbender... |
| 07:24:10 | seven: | Who would found such a hack? |
| 07:24:11 | mandsch: | har har .. |
| 07:24:38 | mandsch: | you'd just need to make a osm-wfs ... |
| 07:24:48 | seven: | Probably yes. |
| 07:25:16 | mandsch: | then have 136 servers with geoserver ... ;- ) |
| 07:25:30 | seven: | Ouch. |
| 07:26:12 | mandsch: | ok, christoph and Astrid are onholidays ...? |
| 07:26:14 | seven: | I don't know. We would need a full OSM dump in one PG instance. No generalized data. |
| 07:26:29 | seven: | Christoph is on holidays this week. |
| 07:26:39 | seven: | Astrid is busy and travles tomorrow. |
| 07:26:52 | seven: | Astrid is very busy currenlty. |
| 07:27:01 | mandsch: | good, isn't it? |
| 07:27:04 | seven: | One can tell when she does not show up here. |
| 07:27:19 | seven: | We had the FOSSGIS e.V. meeting this weekend in LinuxHotel in Essen. |
| 07:27:23 | seven: | She was there too. |
| 07:27:31 | mandsch: | I talked to Marco already a bit... |
| 07:27:34 | seven: | Busybusybusy. |
| 07:27:36 | seven: | OK. |
| 07:27:59 | seven: | We shoudl blog about this or write a report to fossgis-talk but who will do it... ? |
| 07:28:20 | mandsch: | about the fossgis weekend? |
| 07:28:25 | seven: | Yes. |
| 07:28:48 | mandsch: | There were a lot of people i guess ... |
| 07:28:49 | seven: | Can you ping Marco Lechner to add a title to #fossgis IRC chat? |
| 07:28:52 | seven: | he is admin |
| 07:29:04 | mandsch: | yep i can do ... |
| 07:29:17 | seven: | We were 13 in total. |
| 07:29:27 | seven: | Good progress, was a productive meeting. |
| 07:30:08 | mandsch: | I#m still curious what will happen with intergeo ... |
| 07:31:01 | mandsch: | I talked with Olaf about it, the other day ... |
| 07:34:42 | mandsch: | seven: I have to go. Are you around this week? |
| 07:36:29 | mandsch: | ok, have a nice evening. CU. |
