01:30:39 Eclesia: hello
01:31:31 Eclesia: I would like to contact thoses working on official CITE tests : http://cite.geoenterpriselab.com/teamengine
01:31:32 sigq: Title: Welcome ( at cite.geoenterpriselab.com )
01:31:55 Eclesia: there is "huge" problem on the WMS test
01:32:10 Eclesia: It keeps tests wms services using CRS = "CRS:84"
01:32:26 Eclesia: which is not a valid EPSG crs
01:32:46 Eclesia: I guess it should at least by 4326 ...
01:32:52 sevenof9: Eclesia: You chould go to the OGC, the most direct contact is probaly Raj Singh.
01:32:53 Eclesia: be*
01:33:24 Eclesia: you mean the IRC channel ?
01:33:26 sevenof9: The whole EPSG CRS issue is a lot more complex and confusing as it appears and the OGC is working hard on resolving it.
01:33:38 sevenof9: Ah no, I don't think that the OGC is quick on IRC...
01:34:19 sevenof9: For a start you might want to read this: http://wiki.osgeo.org/wiki/Axis_Order_Confusion
01:34:21 sigq: Title: Axis Order Confusion - OSGeo Wiki ( at wiki.osgeo.org )
01:34:44 sevenof9: But it needs an update. Maybe I get around to adding the latest info during FOSS4G.
01:35:03 Eclesia: sevenof9: thanks but I'm a GIS developer already, making a 2D rendering engine, I'm aware of all thoses problesm
01:35:05 sevenof9: The OGC has prepared a manifesto to help solve this probloem.
01:35:19 sevenof9: Eclesia: Sorry, did not want to offend you.
01:35:40 Eclesia: my concern is just to fix the CITE test so that they stop using this stupid "CRS:84"
01:35:44 sevenof9: But I am think the manifesto is not done yet - means it is not publically available.
01:35:47 sevenof9: Hehe.
01:36:23 sevenof9: If you look into this stupid CRS:84 - it actually tries to solve the underlying problem of axis order switching by correctly specifying it.
01:36:39 : * sevenof9 slowly backs off.
01:37:52 Eclesia: so you say this "CRS:84" is something "normal" ?
01:38:56 Eclesia: I havent seen it the specification, and it's also the first time I see this. It really looks like a mistake
01:49:33 Eclesia: sevenof9 : did I afraid you ? :D
03:00:36 crschmidt: Eclesia, who is gone, "Yes, that's normal"
07:02:58 ticheler: darkblue_B: are you involved in the LiveDVD?
07:04:52 darkblue_B: hello tichel
07:05:00 ticheler: hi
07:05:06 darkblue_B: yes, I am testing it a bit
07:05:21 darkblue_B: I'm downloading the new rev
07:05:24 ticheler: I'm absolutely new to this :- )
07:05:50 ticheler: how does the DVD deal with temporary files and so on?
07:05:57 darkblue_B: I use PostGIS and the ogr tools, so I am looking at that part
07:06:03 darkblue_B: its a RAM disk, I believe
07:06:19 darkblue_B: though I am no expert
07:06:22 ticheler: should directories that need write access be configured in a particular way?
07:06:24 ticheler: ok
07:06:59 darkblue_B: it must behave as a standard file system, after it is all started up
07:07:14 darkblue_B: .. so permissions would be just the same
07:07:16 ticheler: so I shouldn't have to worry about that!?
07:07:35 darkblue_B: I have not tried to create a liveCD, so I dont know about that side of it
07:07:45 darkblue_B: there are some links on the Wiki page
07:07:54 darkblue_B: are you going to make some additions?
07:08:39 ticheler: I hoped to do that, although I'm struggling more than I hoped :- )
07:09:28 darkblue_B: ah yes
07:10:22 darkblue_B: did you see the info links at wiki osgeo Live_GIS_Disc ?
07:10:56 ticheler: yes, but should read more carefully I'm sure...
07:11:17 darkblue_B: thats about all I can offer... have another meeting in 20 minutes
07:12:48 ticheler: np
07:13:09 ticheler: off for the weekend
07:14:57 tbowden: if you look at mount while running the live disk maybe you can see what dir's are rw?
07:50:45 : * TylerM waves
07:57:33 bitner: hi TylerM
07:57:38 TylerM: hi bitner
07:57:43 bitner: should we all try to do the wave around the world
07:57:48 : * bitner raises arms
07:57:54 bitner: someone east of MN should go next
08:04:17 tbowden: keeps my hands down for now. Too far east.
08:05:48 : * milovanderlinden raises arms
08:05:55 bitner: woo hoo
08:06:09 milovanderlinden: next should be someone east of the Netherlands
08:06:36 milovanderlinden: germany?
08:06:39 milovanderlinden: russia?
08:06:54 milovanderlinden: I think tbowden will be next!
08:08:34 tbowden: Raises both hands and waves enthusiastically
08:09:54 tbowden: Around the world in four hops I think.
08:09:56 TylerM: _wolf_ missed his chance to put finland on the map
08:45:18 TylerM: rhkfin: by the way, out of the 54 subscribers on the foss-gps list.. i only recognise 3-4 names!
08:45:24 TylerM: should be great for meeting new faces : )
08:46:00 TylerM: wow - 54 subscriptions in less than a day : )
08:48:08 tbowden: Already some interesting intros on the list ( says me lurking there )
08:49:01 TylerM: tbowden: yeah, no kidding
08:49:24 TylerM: oh, you know, we have an auto-unsubscribe for users that don't write within 1 day ;- ) haha
08:49:48 tbowden: Oh good, might solve my osgeo list vortex problem
08:49:59 rhkfin: TylerM: heh : ) Yes, It's cool to see that people are interested!
08:50:23 rhkfin: TylerM: Hmm.. that sound's bad! But there's still many hours time to fix it :9 You do it?
08:50:52 TylerM: hah - just kidding : ) but don't tell tbowden that ; )
08:59:54 TylerM: rhkfin: I hope you saw that it was just a joke : )
09:02:47 tbowden: Joke? Heck, I was relying on that to save me!
09:03:10 TylerM: be careful tim, or i'll run the "password reminder" script.. and fill your inbox : )
09:04:07 : * TylerM wonders how many installations of mailman are used for evil
09:13:45 tbowden: Ah, try as you may, I've already got a filter that handles mailman reminders. Already get way too many!
09:15:03 TylerM: dang..
09:15:10 TylerM: i'll just have to start telephoning you
09:15:18 tbowden: lol
09:15:42 jasonbirch: We've got an account with an emergency dial-out service that I might be able to re-purpose...
09:16:01 tbowden: me dives for cover...
09:20:34 rhkfin: TylerM: that's mean : )
09:20:57 TylerM: you don't know tim ; )
09:21:26 TylerM: hi mlucas - will anyone from OSSIM be at foss4g?
09:24:31 tbowden: I'm always up for a bit of trouble...
09:27:22 sigq: osgeofeed: Ticket #292 ( task created ): Permissions on download.osgeo.org for MapGuide project <http://trac.osgeo.org/osgeo/ticket/292>
09:29:27 mlucas: tylerm, not that I'm aware of
09:29:51 mlucas: I had a conflict this year
09:39:31 tbowden: Anybody know if there is video available from past FOSS4G's? Some of the hightlights might make for good content at the FOSS4G booth this year
09:41:59 jgarnett: There was video from 2006
09:42:04 jgarnett: ( I recall the cameras )
09:42:34 tbowden: Yes, but what happened to the content?
09:42:58 tbowden: did it ever see the light of day, or is it waiting for someone to edit it?
09:52:34 TylerM: tbowden: sitting on dvds beside me : )
09:52:58 tbowden: Ah, the culprit has beem found!
09:53:13 tbowden: or been as the case may be
09:53:51 tbowden: Send em ( Cape Town ), and I'll see what I can do in idle moments.
09:53:55 tbowden: or a copy rather
09:53:58 TylerM: never had anyone volunteer to remix them : )
09:54:07 TylerM: i think it'd be faster for me to upload the iso somewhere..
09:54:16 tbowden: never done it before, but what the heck
09:54:45 tbowden: I'll grab em then. Probably take a hdd full of stuff there if I can.
09:55:21 TylerM: that's the trouble with these things :/ new tech, limited bandwidth, bad tools.. lots space.. sigh
09:55:21 sigq: osgeofeed: Ticket #292 ( task closed ): Permissions on download.osgeo.org for MapGuide project <http://trac.osgeo.org/osgeo/ticket/292#comment:3>
09:55:33 TylerM: i chased my tail for a bit longer than I should have
09:56:04 tbowden: Will we be getting vids from CT?
09:56:58 TylerM: haven't slightest clue
09:57:08 TylerM: but if you want to rent a video camera for interviews at the booth.. go for it
09:57:29 tbowden: k. sounds like a winner
09:57:31 TylerM: i simply found i didn't have enough time to use it though
09:57:45 TylerM: it was last-minute without a plan :/
09:57:54 TylerM: I think the camera scared some people away ; )
09:58:21 tbowden: hmmm. Never done vid production before. Have to learn real quick...
09:58:41 TylerM: i was trying an online streaming tool.. but barely was useful
09:58:45 TylerM: maybe now it is better : )
09:59:04 TylerM: it was nice, theoretically, to be able to stream to web instead of having to save to PC
09:59:10 tbowden: I'll look into what I can do.
09:59:27 tbowden: Streaming is hard. Have to have all the ducks lined up.
09:59:38 tbowden: baby steps first for me
09:59:51 TylerM: this one used a cool little flash or java applet
10:00:32 tbowden: does our new conf software handle vids easily?
10:00:52 tbowden: proly a question for the relevant propeller head...
10:02:59 TylerM: not really a function of the software
10:03:25 TylerM: so, probably no : ) I know the software inside out if you have questions.
10:04:05 TylerM: but its customisable
10:06:00 tbowden: Problem for later today. Time for sleep. Bye all.
10:06:05 TylerM: cya
17:45:54 darkblue_B: wildintellect: hello
17:47:55 wildintellect: darkblue_B, hello - saw your email, been out of town for a few days
17:48:23 darkblue_B: no worries
17:48:38 darkblue_B: I have the a4 DVD running in the Sun VirtualBox VM
17:48:43 darkblue_B: works well :- )
17:48:46 wildintellect: I'm actuall booting the liveDVD in vmware right now
17:49:05 wildintellect: so far so good
17:49:10 darkblue_B: you'll see python 2.5.2 is there
17:49:34 darkblue_B: GEOS and such.. so shapely perhaps?
17:50:16 darkblue_B: I wonder if the python bindings for ogr are there...
17:51:07 wildintellect: hmm, depends what version of ogr too
17:51:35 wildintellect: since there are old and new style bindings
17:52:00 darkblue_B: 1.5.0
17:52:02 wildintellect: but yes my plan is to start figuring out how to move the python stack into the image
17:52:20 wildintellect: maybe we can make it a California chapter project
17:52:51 wildintellect: my goal is to add that by mid november for this thing we do called GIS Day
17:52:57 darkblue_B: ah so
17:53:03 darkblue_B: thats reasonable
17:53:11 wildintellect: it was invented by ESRI, but I plan to co-opt it here at UCD
17:53:24 darkblue_B: we have something like that at Berkeley
17:53:37 darkblue_B: BAAMA does it
17:53:41 wildintellect: I'm sure its the same thing
17:53:57 wildintellect: some of my collegues plan to make an OSgeo poster for it too
17:54:10 darkblue_B: so what do you call the 'python stack' ?
17:55:27 wildintellect: ogr bindings, anything listed on the PCL trac site - so shapely, Wordmill etc, Tilecache and featureserver
17:55:46 darkblue_B: Wordmill... havent heard of that
17:55:56 wildintellect: its an alternative to ogr
17:55:57 darkblue_B: I use FeatuerServer..
17:56:08 wildintellect: http://trac.gispython.org/lab
17:56:09 sigq: Title: PCL - Trac ( at trac.gispython.org )
17:56:11 darkblue_B: cant say I've actually done much with shapely
17:56:35 wildintellect: oops world not word
17:57:16 wildintellect: I've only been playing with it recently, but I've been using other stuff from the group for a while
17:57:24 wildintellect: they hang out on #zco
17:58:39 darkblue_B: simplejson, psycopg2
17:59:27 wildintellect: I should probably start making a list
17:59:33 wildintellect: on the wiki
17:59:55 darkblue_B: aha.. good idea
18:00:21 darkblue_B: I have gdal-1.5.0 as an egg
18:00:29 darkblue_B: so that should be easy
18:01:01 darkblue_B: numpy for the gdal people
18:01:07 darkblue_B: I dont actually use it
18:01:09 darkblue_B: so far
18:02:26 wildintellect: ah cool, I just compiled it myself recently but eggs would be good
18:02:36 wildintellect: did you upload it to pypi?
18:03:13 darkblue_B: nope..
18:03:21 crschmidt: wildintellect: er, it's on PyPi...
18:03:29 crschmidt: has been sicne 1.5 was released, no?
18:03:40 crschmidt: that was howard's big thing
18:04:01 wildintellect: hmm, I don't remember if I looked before I built it myself
18:04:01 crschmidt: windows eggs, macos eggs...
18:04:32 darkblue_B: crschmidt: what other python things do you think should be on the OSGeo Live DVD?
18:05:17 : * crschmidt has no idea
18:05:30 crschmidt: Depends entirely on the target audience
18:06:08 darkblue_B: well some made noises about the difffernce between developers and GIS users
18:06:14 darkblue_B: but to me, thats not so clear
18:06:30 darkblue_B: I come from beng a sfwr developer, and I think of tools as ways to make things
18:06:38 darkblue_B: I would think that there are others like that
18:06:50 crschmidt: You're not a representative sample, in my opinion
18:06:52 darkblue_B: I dont see it as GIS users.. really
18:07:09 wildintellect: I'm a gis user, who doesn't get how you really do GIS analysis without scripting
18:07:17 darkblue_B: well, whats representative in a quickly changing world? but ok
18:07:29 darkblue_B: aha
18:08:05 wildintellect: I originally got into VB/VBA in Arc years ago and jumped to python maybe 4 years ago
18:09:07 wildintellect: from the perspective of my school's graduate level program, most of the students who focus on GIS start programming at some point
18:09:52 wildintellect: sure there are plenty of others who just use what they're given, but having a disc that demos what can be done tends to help jump start
18:10:17 wildintellect: especially now that ArcGIS can read/write PostGIS
18:10:49 darkblue_B: I have *heard* of that... I havent *seen* t
18:11:56 crschmidt: It is my opinion that it is hard to meet the needs of a developer in GIS without them needing to install more stuff, unless you're trying really hard to shove everything in
18:12:04 crschmidt: It's much easier to concentrate on the things that demo well
18:12:20 crschmidt: and putting those together in a coherent vision can allow you to 'draw people in' ... such that they *want* to go out and get more software
18:12:39 crschmidt: I would personally put 'prettiest examples first' in building a Live-disk
18:12:54 darkblue_B: pretty python scripting corner...
18:13:34 wildintellect: I agree, for programmers the best thing is examples of what the software could do, and for GIS users - showing that it's not that hard to use, install, configure
18:13:56 darkblue_B: well from another angle, I would like to think that wildintellect has a point about scripting being fair game
18:14:43 wildintellect: if I wanted to target programmers, I'd be suggesting OSSIM and all the C++ api docs for that and QGIS
18:15:24 darkblue_B: well thats a handfull!
18:15:38 darkblue_B: I am not sure anyone from OSSIM is going to FOSS4G
18:15:44 darkblue_B: I thought I saw that go by
18:16:14 darkblue_B: programming means Java for a lot of operations
18:16:21 darkblue_B: C++ is really sfwr development!
18:16:31 darkblue_B: ( thats what i did in a previous life )
18:17:11 darkblue_B: and I havent done any Java in this life
18:17:25 darkblue_B: just python.. which brings it full circle ;- )
18:17:43 wildintellect: so I'd say lets rank the possible add-ons into priority groups based on what's easiest to get into and most useful to GIS users learning to script
18:18:02 darkblue_B: sure.. thats pragmatic
18:19:51 wildintellect: ogr is pretty common, and I think shapely is pretty cool for basic operations, not to mention the only PCL component that easily installed on my machine
18:20:30 wildintellect: then featureserver and tilecache are just tools people really should see in action
18:20:37 wildintellect: those would be my top pikcs
18:20:38 wildintellect: picks
18:20:45 darkblue_B: sounds good
18:21:35 darkblue_B: there is a live apache running on it right now
18:22:09 wildintellect: yup, and geoserver which we could borrow a WMS from for tilecache
18:23:26 wildintellect: oh and featureserver relies on ogr bindings for shapefiles
18:24:22 darkblue_B: sure
18:24:33 darkblue_B: openlayers is embedded in the geoserver
18:25:32 darkblue_B: in /var/lib/tomcat5.5/webapps/geoserver/...
18:46:49 wildintellect: darkblue_B, don't forget to add your testing results to the wikipage
18:47:37 darkblue_B: well, this time.. things went pretty well :- )
18:47:45 darkblue_B: I am not sure found anyhting that didt work
18:47:54 darkblue_B: a2 was screwy
18:48:16 darkblue_B: I guess I can mention the Sun VirtualBox
18:48:23 darkblue_B: its a free download
18:51:02 wildintellect: I almost hosed a machine on friday trying to install VirtualBox without following instructions
18:51:16 wildintellect: but yes a good deal
18:54:21 darkblue_B: yow! well I got the .deb from the site for vbox 2
18:54:24 darkblue_B: worked fine for me
18:55:19 wildintellect: ah I think I used the repo for some reason I setup on one machine and forgot what I did
