| 00:42:33 | kingcharles: | anyone can help me with layers refresh for a real-time apps qith qgis ? |
| 01:20:54 | milovanderlinden: | Hi all, serious issues with Ubuntu Jaunty 64bit have caused me to use another linux distro. I am now on #! crunchbang linux which is intrepid based. I pointed to ppa.launchpad to get qGIS unstable, it installed. But when I run it I get Segmentation fault. How can I debug the run process? |
| 01:21:47 | kpanic: | milovanderlinden, same here, I apt-get build-dep qgis, downloaded the latest qgis and recompiled. works like a charm |
| 01:22:31 | kpanic: | milovanderlinden, I was getting segfault in the 'style editor' |
| 01:23:44 | milovanderlinden: | kpanic, gonna try build-dep, thanks! |
| 01:24:30 | milovanderlinden: | w00t, it requires 75 new packages :D.. |
| 01:31:29 | kpanic: | milovanderlinden, hope it will work. yeah a lot ! |
| 01:33:31 | milovanderlinden: | kpanic; not yet. I will try to reboot and see if that works |
| 01:33:45 | milovanderlinden: | otherwise I need a way to get details on the segmentation fault. |
| 01:33:49 | kpanic: | milovanderlinden, okay |
| 01:34:05 | milovanderlinden: | back in a few sec. |
| 01:37:52 | milovanderlinden: | still a segmentation fault. |
| 01:39:05 | milovanderlinden: | no messages on /var/log/messages |
| 01:40:44 | kpanic: | milovanderlinden, yes, maybe 'strace' it |
| 01:45:13 | milovanderlinden: | thanks kpanic, I tought strace needed source code. bit newb on that terrain.. |
| 01:45:34 | kpanic: | milovanderlinden, nope, at least you see where at lowlevel it fails |
| 01:45:36 | macho: | I'd always prefer building it from source rather using a package |
| 01:46:19 | milovanderlinden: | that is indeed macho, macho ;- ) I did build from source too before, but I dislike the fact that I do not get auto update messages then |
| 01:48:31 | macho: | depends on what you want .. building qgis froum source takes about 10min here |
| 01:48:39 | macho: | and once in a week i rebuild it from svn |
| 01:49:36 | milovanderlinden: | macho: darn! I want that too! |
| 01:52:17 | milovanderlinden: | strace throws a lot of ( No such file or directory ) errors at me.. |
| 01:52:54 | milovanderlinden: | If I want to go for "from source" do I need to apt-get remove qgis and all the dependencies or qgis only? |
| 02:03:32 | macho: | i do not even have some of the qgis repositories inside my sources.list |
| 02:10:31 | milovanderlinden: | But if you build from source, do you have everything there including qt4 and the grass connections? |
| 02:11:32 | macho: | of course |
| 02:12:06 | macho: | it can even be compiled with connection to the recent grass svn build ( which i also do myself ) ; ) |
| 02:14:16 | milovanderlinden: | macho, do you want to share your method? I would love to build from source too |
| 02:14:43 | macho: | of course i will - but i'm at work currently - and on windows :( - my linux pc is @home |
| 02:15:03 | milovanderlinden: | It would even be nice to create a howto for the qgis community, but only if you would like that |
| 02:26:06 | macho: | hmmm - once i find out which dependencies building qgis in a debian environment has - i'll do a wiki page |
| 02:29:09 | milovanderlinden: | macho: If you create a starting point; I can always help. |
| 02:29:11 | macho: | i always have a parallel install of stable and current trunk side by side .. that very helpful sometimes .. |
| 02:29:19 | milovanderlinden: | No need to work out the ins and outs alone |
| 02:29:48 | milovanderlinden: | Yeah, that sounds great, having two side by side is excellent for instance for testing translation |
| 02:30:01 | macho: | : ) thats what i do .. |
| 02:30:12 | macho: | my job as translation coordinator .. |
| 02:35:12 | il_rugginoso: | hi all |
| 03:05:14 | strk: | jef: for the record. I'm using my version of that postgis layer loader and I'm very happy with it. Would be a pity to loose mainstream. |
| 03:05:31 | strk: | to recap, my version simply always uses <tablename>.<columname> |
| 03:05:38 | strk: | for sure it's not necessarely always good |
| 03:05:47 | strk: | for the reason you mentioned ( it's usually always the_geom ) |
| 03:05:52 | strk: | and cause someone would also want the schema |
| 03:06:02 | strk: | so my final proposal for The Way To Do It ( tm ) is: |
| 03:06:13 | strk: | let user specify that in the configuration file : ) |
| 03:06:36 | strk: | LayerNameFormat %d.%s.%t.%c |
| 03:06:44 | strk: | ( database, schema, table, column ) |
| 03:07:12 | strk: | point me to a place where I can record the "feature request" if you have one please : ) |

| 13:51:57 | jiho: | Hi everyone. Newbie to qgis here. I have a IKONOS satellite file that is supposed to be GeoTIFF ( it comes as a tiff file accompanied by .ers and .tfw files with the same name ). The documentation says the datum/projection is GDA94/MGA55 ( the image is from Autralia ). However, when opened in qGis the default WGS 84 is used and the coodinates look like 335413,8374684 so nowhere like lat,lon couples. |
| 13:52:30 | jiho: | I though GeoTIFF's had this information embedded. Is there anything special I should care about when opening the image? |
| 13:53:46 | macho: | jiho: try to define the projection before you open the file |
| 13:53:57 | macho: | there are some issues with decent projections and datums .. |
| 13:54:05 | macho: | long outstanding bugs .. :( |
| 13:54:14 | jiho: | in case someone is interested in looking at the files directly, here are links: |
| 13:54:14 | jiho: | http://files.getdropbox.com/u/1047321/GeoTif/Lizardisland_240905.tif |
| 13:54:15 | jiho: | http://files.getdropbox.com/u/1047321/GeoTif/Lizardisland_240905.tfw |
| 13:54:15 | jiho: | http://files.getdropbox.com/u/1047321/GeoTif/Lizardisland_240905.ers |
| 13:54:15 | jiho: | just note that the tiff files is ~150MB |
| 13:54:33 | jiho: | macho: thanks, trying that now |
| 13:54:47 | macho: | mostly caused by other programs writing out none standard projection definition files |
| 13:59:05 | jiho: | macho: you mean setting the projection for the project right? |
| 14:01:15 | macho: | yes |
| 14:02:18 | jiho: | macho: if I set GDA94/MGA55 in project properties, tick "enable on-the-fly" CRS transfornation, then add a raster layer with the tif files, nothing appears and I have an invalid scale message in the botom right of the status bar |
| 14:04:56 | jiho: | macho: is there any way I can check that the GeoTiff file is actually georeferenced? |
| 14:05:07 | macho: | i'll look at it tomorrow |
| 14:05:33 | jiho: | macho: thanks that's very kind of you. in which timezone are you? |
| 14:08:59 | macho: | GMT+1 Europe/Vienna |
| 14:09:10 | macho: | hmm - summertime - so i guess its GMT+2 |
| 14:09:20 | jiho: | oh that's late for you indeed! |
| 14:09:34 | jiho: | my email is jo.irisson ( at ) gmail.com |
| 14:09:45 | macho: | what is your timezone? |
| 14:10:04 | jiho: | I am in the eastern US so I will only be able to connect to IRC sometime in the afternoon for you |
| 14:10:08 | jef: | I don't think there is any usable projection information. the .ers file is not used. |
| 14:10:42 | jiho: | jef: "any usable projection" in the Tiff file you mean? |
| 14:10:46 | macho: | for projection there should be a .prj file .. |
| 14:10:49 | jef: | I'd just set the CRS in the layer properties. |
| 14:10:50 | jiho: | I see |
| 14:10:54 | macho: | but i've had a simmilar problem a few month ago |
| 14:11:08 | macho: | and it was hard to tell qgis howto load the geotiff properly |
| 14:11:38 | jiho: | OK. well it is a very small region so the exact projection used should actually not matter very much |
| 14:11:54 | jiho: | what I am most intrested in it getting lat,lon coordinates that make sense |
| 14:12:14 | macho: | what lat lon are you expecting? |
| 14:13:29 | jiho: | around S14.6 and E145.5 |
| 14:14:08 | macho: | ok - maybe i've time tomorrow to take a look at |
| 14:14:14 | macho: | good night .. |
| 14:14:21 | jiho: | thanks very much again |
| 14:14:24 | jiho: | good night |
| 14:14:43 | jef: | jiho: set the CRS in the layers properties to GDA94/MGA55 and the project's CRS to WGS84 and enable on-the-fly projection |
| 14:15:08 | jiho: | jef: trying that now |
| 14:17:23 | jiho: | jef: the image disappears when I do that. Basically I need the CRS to be the same in both the layer and project otherwise I just see a blank page |
| 14:17:43 | jiho: | trying to zoom to the extent of the data does not seem to do anything |
| 14:17:59 | jiho: | ( in case the change of project just shifted the image somwhere else ) |
| 14:18:08 | jiho: | projection* |
| 14:18:10 | macho: | oh - jef is here : ) |
| 14:20:02 | jiho: | jef: oh something interesting though: by doing what you advise, I get valid coordinates ( hovering the mouse over the map gives me values of 145 and -14 ) |
| 14:21:39 | macho: | so it works now? |
| 14:22:34 | jiho: | oh qgis just hanged and I had to kill it |
| 14:22:57 | jiho: | it seems qgis was eating all my RAM |
| 14:23:27 | jiho: | so maybe I was just seeing a blank page because qgis was in the process of rendering the image |

| 14:30:36 | jiho: | jef: anything else I can test? |
| 14:37:09 | jef: | jiho: well, not a big raster user on this end. looks like the vector approach doesn't work well on rasters. |
| 14:41:13 | jiho: | jef: sorry, I did not see your reply |
| 14:41:55 | jiho: | ok. actually my goal is to contour the fetures I am interested in and get vectors instead of raster. |
| 14:42:02 | jiho: | I also want to get away from the raster |
| 14:42:04 | jiho: | ; ) |
| 14:42:32 | jiho: | it seems to work since I now get correct coordinates. there just seems to be a problem with the drawing of the map |
| 14:42:38 | jiho: | thanks for your help anyway |

| 14:47:34 | jiho: | thanks a million |
| 14:47:56 | jef: | jiho: np |
| 14:48:05 | jiho: | now I'll digitize the parts I am interested in and export the shapefiles |
| 14:49:24 | jiho: | while I am here. qGis only produces ESRI shapefiles when I start a new vector layer. Is there a way to export them to simple x,y coordinates ASCII files from within qGis afterwards? |

I had it before, but this time, I am getting a splash screen flashing ( one step further then before ) I strace'd it. Is someone able to look at the strace output and maybe help me see what is wrong? |
| 14:49:55 | jiho: | Otherwise I will compile shp2txt. but if there is something already in qgis that would be easier |
| 14:55:21 | jef: | jiho: not sure. the ogr converter might work. shape to csv |
| 14:56:40 | jiho: | thanks. I tried that but could not get it to work. probably just a problem on my end. |
| 14:57:07 | jiho: | jef: thanks again for you help. have a nice evening/morning/night |
| 14:59:46 | jef: | jiho: you too |
| 15:01:41 | FiReSTaRT: | hey juergen.. how you doin? : ) |
| 15:02:30 | jef: | tired. ; ) |
| 15:05:08 | FiReSTaRT: | i know what you mean... been handling some logistical issues for a client in chile and it's been NUTTS... i was supposed to be back in santiago 3 days ago and i don't think i'll be going back until tuesday |

| 16:01:42 | CIA-65: | -removed the use of setPixel( ) in the rendering routines, thanks Yan for the suggestion |
| 16:01:42 | CIA-65: | -swapped all of the myColumns and myRows in the rendering routines, as they were reversed |
| 16:07:19 | jiho: | jef: Thanks to you I am finished with my tracing and I got the coordinates in the format I wanted ( it turns out R, which I am using afterwards, can read shapefiles just fine ! ). Here is the result if you are interested: http://files.getdropbox.com/u/1047321/Picture%202.png |
| 16:07:26 | jiho: | Thanks again |
| 16:08:51 | jiho: | gotta go |
