[Qgis-developer] How do datum transformations work?
Hi, I am struggling to find out how datum transformations work - specifically also under QGIS Server. I have a .gsb file (CHENYX06a.gsb) for Swiss datum transformations. It is located under /usr/local/shar/proj/ where all the other .gsb files are. I also set the DEFAULT_DATUM_TRANSFORM variable variable in my fcgid.conf file: FcgidInitialEnv DEFAULT_DATUM_TRANSFORM "EPSG:21781/EPSG:2056/11/-1;EPSG:2056/EPSG:21781/-1/11" I checked the entries in the srs.db on the server in the table tbl_datum_transform which has an entry: wkt_geom coord_op_code epsg_nr source_crs_code target_crs_code coord_op_method_code p1 p2 p3 p4 p5 p6 p7 remarks scope preferred deprecated area_of_use_code NULL 11 15486 4149 4150 9615 0 But how does QGIS know that it should use the CHENYX06a.gsb file as grid-shift file? Where exactly does it find this information? Thank you for shedding some light on this mystery.

That would be the simplest solution. yakkety has pyqt5-dev-tools=5.7+dfsg-2. But it actually depends on python3-pyqt5=5.7+dfsg-2, which in turn is depends on libqt5core5a (>= 5.6.0~beta) - which is libqt5core5a=5.6.1+dfsg-3ubuntu6~4 in yakkety (see [0] ff) So no need to downgrade pyqt5 - it's built against Qt 5.6.1. > PyQt5 or package `python-pyqt5` can be removed and installed with > `sudo pip3 install` using the Qt 5.6.1 `.whl` file. Mixing debs and pip might create a mess. I'd avoid that. And given the above, there's no need to anyway.

Re: [Qgis-developer] newbie build, run question
Hello Chris, QgsMapLayerRegistry does not exist anymore (since some weeks). It's methods have been moved to QgsProject to allow having multiple project open at the same time. So the GdalTools plugin does not seems up to date or compatible with current master branch of QGIS. I'm not really aware of that plugin, but I do not see it in QGIS core repository. Maybe this is an obsolete thing, and you could just remove it. Have you followed the install doc : https://github.com/qgis/QGIS/blob/master/INSTALL For using custom build of QGIS, you should : Change CMAKE_INSTALL_PREFIX to some folder in your home instead of default one in system folder https://github.com/qgis/QGIS/blob/master/INSTALL#L256 And run QGIS using : export QGIS_PREFIX_PATH=~/apps/qgis-master export LD_LIBRARY_PATH=$QGIS_PREFIX_PATH/lib $QGIS_PREFIX_PATH/bin/qgis With a fresh build/install you should not get this error.
