QGIS 3 is not yet there and there is still plenty of time to prepare and migrate. But I thought I would give some advice about things that you can keep in mind while working on your plugins to make your life easier when you will have to actually do the migration. It’s mostly about making your code prepared for Python 3 and PyQt5. Do not use star imports Don’t do from PyQt4.QtCore import * Read more…
Processing just got a new testing framework to improve the long-term stability of this important plugin. And you can help to improve it, even if you are not a software developer! This is yet another piece in our never-stopping crusade to improve the stability and quality of the best desktop GIS on the market. Processing You probably know processing. If you don’t: processing is the number one plugin to enable after every QGIS installation. It offers a Read more…
After getting QField up and running in Android 5, we felt it was time to start documenting how QField works, we started documenting how to install and use QField. We also added a section on how to handle your data to get them on QField. It is all pretty basic, but it dose give some hints. You can find the documentation here: https://qfield.org/docs/ As QField’s source code the docs are opensourced (on github) and we look Read more…
Working on QField I had the necessity of passing values from the QtActivity.java to the Qt cpp world, here how I did it using an Intent that is sent to the QtActivity (the one you should not edit that comes with Qt). For much more information see this post series. hopefully this will be helpful to someone. private void startQtActivity() { String dotqgis2_dir = « Test dotqgis2_dir »; String share_dir = « Test share_dir »; // forward to startQtActivity and Read more…
While preparing some 3D scenes for an exibition I discovered the SpaceMouse by 3dconnexion. A neat device we plan on installing in front of a projected globe. To get it to run in Ubuntu first get the drivers from www.3dconnexion.eu/service/drivers.html then sudo apt-get install libmotif3 mkdir -p /tmp/3D3dxware-linux cd /tmp/3D3dxware-linux cp ~/Downloads/3dxware-linux-v1-8-0.x86_64.tar.gz /tmp/3D3dxware-linux tar -xf 3dxware-linux-v1-8-0.x86_64.tar.gz sudo ./install-3dxunix.sh answer yes, 4, yes. That’s it, you might get an error saying: « Red Hat EL 7 currently Read more…
Whenever you start QGIS you basically do it because? Right, because you need to do GIS work. Ah, how I love rhetorical questions to start a post. And most of the time one continues to work on a QGIS project which he has prepared before. For me 99% of the time, I start QGIS, move the mouse to the top left over « Project » go to « Recent Projects » and select the one I want. If I am lucky Read more…
PyQGIS now supports a nice new addition for handling edit sessions in layers. This way, changes get committed automatically at the end of a successful (python) edit session.
