Re: [Qgis-developer] QGIS CRS handling question
Otto - The first question - I you look at the information from "ogrinfo" in the first case it contains: ... DATUM["unknown", SPHEROID["unretrievable - using WGS84",6378137,298.257223563], ... This is plainly wrong for EPSG:25833. It should be something with GRS80. You might have a bad installation of the GDAL utilities. And this error is probably triggering QGIS to ask for the projection. For the next question: I haven't actually looked at the QGIS code for CRS lookups, but I'll make a guess: QGIS do a search in the build-in projection database and find the epgs:3006 as the first candidate and doesn't look any further. You might have a look on this thread: http://lists.osgeo.org/pipermail/qgis-user/2013-February/021233.html , which describes a somewhat similar situation Regards Bo Victor Thomsen AestasGIS Denmark On 22-05-2015 09:42, Otto Dassau wrote: Hi, I would like to understand QGIS behavior a little better for CRS handling.

Re: [Qgis-developer] issue with QGIS via citrix
Wisse - You might have some kind of network problem that pops up up between you Citrix server and the network share used to store the shape files. Try to create a share locally on the Citrix server and save the shape files to this share instead. The problem could be some kind of file access conflict with several users reading the shape file at the same time as another user is trying to edit the same shape-file. Try to edit the shape-file at a time when you are sure no other user are accessing the file. When you have a multi-user, perhaps multi-edit environment as yours my strong, general advise is to store the data in a database like postgresql/postgis. Any file based format like shape-files, tab-files or spatialite is not suitable for this kind of environment.

Hi, we have the very same config here. No report of such troubles here until now (not meaning that it does not happens). 2.6.1 encounters mainly troubles with corrupting some qgs on save. More generally with QGIS, we have troubles having a good screen reactivity with thin clients WYSE, when receiver clients on PC work very smoothly. Any feedback?

[Qgis-developer] Compile QGIS master with support for GRASS
I am compiling qgis from master (git). Both GRASS and GRASS7 are set to ON and the the corresponding GRASS_PREFIX, GRASS7_PREFIX are set to /osgeo/grass64/dist.x86_64-unknown-linux-gnu and /osgeo/grass70/dist.x86_64-unknown-linux-gnu. I launch QGIS without installing it, ie from inside the bin directory. It runs fine. However, I can't see anywhere in QGIS' interface any reference to GRASS. Plus, many of the icons do not appear at all (ie icons of the advanced digitizing bar). What am I doing wrong?

Hi all, we already agreed about replacing fTools (not sure about GDALTools) with Processing algorithms. If I'm not wrong there is even some work in progress in this direction.
