QGIS User Meeting Bern 21.4.10
Am 21. April 2010 findet das erste deutschsprachige QGIS User-Meeting in Bern statt. Das Programm und die detaillierten Angaben können auf der QGIS-Homepage nachgelesen werden. Sourcepole stellt bei dieser Gelegenheit ihr OpenLayers-Plugin vor, das Google Maps und Konsorten als QGIS-Layer ins Desktop-GIS integriert. Alle QGIS-Anwender und Interessierte sind herzlich zu diesem Anlass eingeladen!
FOSSGIS 2011: Webgis mit QGIS und GeoExt
Neues vom QGIS Server Der Vortrag zeigt die Fortschritte von QGIS Server auf, illustriert auch anhand von Beispielen aus der Praxis. QGIS Server kann neu .qgs Projektfiles aus dem Desktop-GIS-Bereich als zentrale Konfigurationsdatei von Webdiensten (derzeit nur WMS) verwenden. Das bietet verschiedene Vorteile: Desktop-GIS, Web-GIS und WMS aus der gleichen Konfigurationsdatei kein manuelles Editieren von .map-Files - auch Mapserver-Laien können nun sehr einfach Webdienste erstellen Übernahme von Druck-Layouts für das Drucken im Web (derzeit in Arbeit) Verwendung der neuen Label-Engine und der erweiterten Symbolisierungsmöglichkeiten aus der neuen Symbology-Engine Die Client-Komponente wurde mit GeoExt (OpenLayers, ExtJS,GeoExt) realisiert.
Multithreaded rendering with QGIS
Nowadays, most computers have several processor cores. However, most computer programs are still designed to only use one processing unit. As a convenient and portable way of writing software using all the available processing power, Qt provides the excellent QtConcurrent framework. In 2010, a Google Summer of Code project examined the suitabilty of using Qt concurrent for rendering the map image in QGIS using several processor cores. Following that approach, each layer renders its image in a separate thread.
The state of QGIS Globe
The Region of Umbria, Italy, sponsored 4 days of work to update QGIS Globe for current QGIS versions. Most of the functionality is working again and the globe is now compatible with osgEarth 1.0 up to 1.3. The bad news is, that the globe plugin is not working on Windows with OSGeo4W. It seems that one of the OSGeo4W libraries (GDAL?) is compiled with an incompatible MS compiler version. Christmas holidays are coming…
FOSSGIS 2013: Performance optimised wms services with QGIS server
Performance is usually a top priority for a WMS service. A recent talk at the FOSSGIS (held by Sourcepole) shows what a WMS administrator can do to optimise QGIS server performance. Finally, the performance of QGIS server is compared with UMN mapserver in two production scenarios. Slides from FOSSGIS 2013 in Rapperswil (in german).
AutoForm Plugin for QGIS
The AutoForm plugin for QGIS automatically sets the edit widget type for the fields of a selected layer based on their data types and foreign keys. This is in order to save the user time they may need to spend on manually editing these widgets.
Publish Image Tooltips with QGIS Cloud
A lot of people are using QGIS Cloud as a service with ready to use QGIS webclient. It’s very easy to publish data and share maps in this way. Publishing of georeferenced images can be done with QGIS Cloud in a few steps as well. But the main problems are: how to upload the images into the cloud database? how to manage them? how to display the results? QGIS and QGIS Cloud are offering all tools for this task.
Web based printing with QGIS server
QGIS server is already known as a full featured, WMS 1.3 compliant map server (see e.g. ETHZ, Linfiniti or 3LIZ). For the city of Uster, Switzerland, Sourcepole recently extended QGIS server with the possibility to use the print composer via WMS in order to offer printing functionality for web maps. A very nice GeoExt based client can be found at http://gis.uster.ch/webgis/. Andreas Neumann used and extended the GeoExt PrintProvider and PrintExtent classes which allows the user to intuitively select a layout, extent, scale, rotation and resolution for printing.

Reduzieren sie die Kosten ihrer Geodaten Infrastruktur da keine Software-Lizenzen anfallen.
Shaded relief maps with QGIS
Creating a shaded relief map from digital elevation data is a nice way to create a backround map for web mapping or other GIS work. Thanks to the know-how and the funding from the Swiss Humanitarian Aid Unit, QGIS now has a sophisticated function for relief map generation. The method is described in detail in an paper by Marc-André Bünzli. An important part of the method is the choice of the elevation colors.
OpenLayers plugin visits code sprint
A short visit and 7 hours train ride to the OpenLayers code sprint mainly for a presentation at the Swiss MapFish user group meeting in Lausanne, resulted in a new release of the QGIS OpenLayers plugin. The OpenLayers plugin adds WebKit based layers to QGIS and ships with OpenStreetMap-, Google- and Yahoo-Layers. Changes in this release: Update to OpenLayers trunk Google Layers using API V3 (no API key necessary) Code refactoring for adding new layer types with one line of code (and some HTML…) The next planned step is integrating this plugin with the very nice Openlayers Overview plugin from Luiz Motta.

Slides from our presentations at FOSS4G 2015 in Seoul: Keynote: The QGIS project and its evolution from a desktop GIS to a GIS platform - Slides New QGIS functions for power users - Slides QGIS Plugins - From Must-Haves to insider tips - Slides Building an OpenLayers 3 map viewer with React - Slides Thanks to the organizers of this great conference! It was a pleasure to get in contact with so many users from around the world.
Eigene GIS-Fachapplikationen mit QGIS entwickeln
Als Ergebnis der Zusammenarbeit zwischen der Sourcepole AG und der Hochschule Rapperswil (HSR) ist ein Video entstanden, dass die Entwicklung eigener Fachschalen mit QGIS beschreibt. Am Beispiel der Zonenplanung zeigt dieses Video, wie Sie mit Quantum GIS eine so genannte Fachapplikation erstellen könne. Sehen Sie Schritt für Schritt, wie sie Quantum GIS auf Ihre persönlichen Bedürfnisse anpassen können, passende Erweiterungen finden, eigene Eingabeformulare erstellen und eine Datenbank verwalten. Die Grundlage zu diesem Video war ein Workshop auf dem Geosummit 2012 Bern, den Pirmin Kalberer entwickelt hat.
Zonal statistics plugin for QGIS
To install: unpack zonal_statistics.tgz under /src/plugins, insert zonal_statistics as new subdirectory in /src/plugins/CMakeLists.txt and recompile
Offline editing plugin for QGIS
For data collection, it is a common situation to work with a laptop or a phone offline in the field. Upon returning to the network, the changes need to be synchronized with the master data source, e.g. a PostGIS database. If several persons are working simultaneously on the same datasets, it is difficult to merge the edits by hand, even if people don’t change the same features. Therefore, Mathias Walker implemented an offline plugin for QGIS.
QGIS Mobile GSoC has started
Yesterday, we had our first meeting with Marco Bernasocchi, who just started his Google Summer of Code project. The project goals are: porting QGIS to the Android platform adapt the QGIS GUI for tablet computers write a driver for the built-in GPS create a QGIS “mini” application for mobile phones Marco Hugentobler is mentoring the project and updated information will be available on a QGIS Wiki page. We wish Marco good luck and are looking forward to a portable QGIS this year!
Creating png8 images with QGIS server
For providing maps via WMS over the internet, it is important to generate image files with a small size. Because normally, most of the perceived WMS delay comes from transfering large images files over the internet (and not from map rendering itself). Therefore, QGIS server supports the conversion of png24 and png32 images into png8, therefore generating a file with only 1/3 resp. 1/4 of the original size (but with lower quality).
