FOSSGIS 2019 in Dresden
Sourcepole war an der FOSSGIS 2019 in Dresden als Austeller, mit Vorträgen und einem Vektor Tile Workshop präsent.
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
Raster resampling in QGIS
QGIS already offers a lot of possibilities to visualize raster data (contrast enhancement, color map, handling of transparent pixels, …) Last year, Radim Blazek refactored the raster provider interface and added on-the-fly reprojection support for rasters to QGIS. Very cool! One of the few things currently missing in QGIS raster layer is the possibility to have other resampling types than nearest neighbour. The problem is that rasters appear pixelated when zooming further than the source raster resolution.
QGIS Enterprise - Open Source GIS mit LTS Support
Das benutzerfreundliche und funktionsreiche Quantum GIS (QGIS) bewährt sich seit mehreren Jahren im professionellen Einsatz. Die Firma Sourcepole aus Zürich füllt jetzt eine letzte Lücke, die Organisationen davon abgehalten hat QGIS in Unternehmens-Infrastrukturen einzusetzen – der professionelle Support direkt von den Kernentwicklern. Mit dem QGIS Enterprise Long Term Support- und Wartungsvertrag erhält der Kunde die Sicherheit, eine professionell unterstützte und betriebsbereite GIS Infrastruktur auf der Basis von QGIS zu betreiben.
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…
Share and manage your Data with QGIS Cloud and WFS-T
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. But QGIS Cloud has more power under the hood. A not so obvious feature of QGIS Cloud is the option to share your data via Web Feature Service (WFS) and manage them via Web Feature Service Transactional (WFS-T). “The basic Web Feature Service allows querying and retrieval of features.
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).
QGIS Cloud - Speed up the loading time of the web client
QGIS Cloud is your personal geo-data infrastructure in the internet. Publish maps and data. Share geo-information with others. And all of this very easily, without server, infrastructure and expert knowledge. If you know QGIS Desktop, then you know QGIS cloud just as well. Just install the QGIS cloud plugin from the official QGIS plugin repository and you’re good to go. You can publish as many maps as you want. But the default settings of QGIS projects you like to publish via QGIS Cloud are not the best with respect to the performance of the QGIS Webclient / WMS.

NTv2 transformations with QGIS
Datum transformations with grid shift files are used in several countries to convert coordinates between different datums. In Switzerland, datum transformation using the NTv2 method is important because of the upcoming conversion between the LV03 system and the new LV95 system. Up to now, doing coordinate transformations with grid shift files was possible in QGIS, but unconvenient. To use an NTv2 transformation in QGIS, the grid shift file needs to be placed in a directory where proj4 can find it (usually /usr/share/proj on Linux and OSGeo4W\share\proj on Windows).
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.
FOSSGIS 2011: Neue Entwicklungen und Features vom Quantum GIS Projekt
Das QGIS Projekt hat zum Ziel, ein plattformunabhängiges, einfach zu bedienendes und offenes Desktop GIS zu entwickeln. Im vergangenen Jahr hat die Aktivität in der QGIS-Community erneut zugenommen. Seit der letzten FOSSGIS Konferenz in Osnabrück hat sich QGIS wieder enorm weiterentwickelt. Sucht man sich (aus der Liste der svn commits) alle Neuerungen des letzten Jahres heraus, so kommt man auf eine Liste, die den Rahmen dieses Artikels bei weitem sprengen würde.
New configuration options in QGIS server
In QGIS server, it is now possible to selectively exclude layers from WMS publication. These layers will be available only on the desktop and hidden from WMS clients. Similarly, print layouts can be excluded from WMS publication. Of course, these settings are conveniently accessible from the project properties dialog of QGIS (but you need to have a nightly build or a recent compile): Additionally, attributes per layer can be excluded from WMS or WFS publication in the vector properties dialog:
SVG symbols in QGIS with modifiable colors
SVG markers are a popular way to symbolise points in QGIS. Predefined markers are available in $PREFIX/share/qgis/svg and it is straightforward to add new symbols or to create own symbols with a vector graphics program (e.g. Inkscape). A disadvantage so far was the need to create different versions of an svg file to have the same symbol in several colors. A recent change in QGIS now introduces the possibility to insert parameter tags into the svg file and QGIS is going to replace them with the values for fill color, outline color and outline width.
FOSSGIS 2017 in Passau
In zwei Wochen beginnt die alljährliche deutschsprachige FOSSGIS Konferenz zum Theme Open Source GIS und OpenStreetMap in Passau.
FOSS4G 2018 Dar es Salaam
This year’s FOSS4G edition took place in Dar es Salaam, Tanzania. As every year, Sourcepole was supporting this major event as a sponsor. We would like to thank for all the interesting discussions and feedback to our presentations!
QGIS 1.5 und QGIS Mapserver 1.0
Kurz nach dem Release von QGIS 1.5, das mit vielen neuen Funktionen aufwartet, ist auch der QGIS Mapserver in der Version 1.0 verfügbar. Der QGIS Mapserver ist ein WMS Server, der ursprünglich am Institut für Kartographie der ETH Zürich entwickelt wurde. In der Version 1.0 können neben der Symbolisierierung mit SLD auch QGIS-Projekte direkt als WMS publiziert werden. Dank der von Sourcepole entwickelten nativen Unterstützung von QGIS-Projekten, können mit QGIS erstellte Karten ohne Konvertierungverluste direkt als WMS-Dienst publiziert werden.
Folien QGIS User Meeting Bern
Das erste deutschsprachige QGIS User Meeting in Bern war mit rund 80 Teilnehmern ein grosser Erfolg. Die Folien der Präsentation des OpenLayers-Plugin sind hier erhältlich. Die gesammelten Präsentation werden auf der QGIS-Homepage veröffentlicht.
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!
„Geo For All“ - neue Technologien für eine Welt im Wandel
GEOSummit 2014, Bern „Geo for all“ ist nicht nur das Motto der weltumspannenden ICA-OSGeo Lab Initiative zur Förderung der GIS-Ausbildung an Hochschulen, sondern steht allgemein für den immer breiteren Zugang zu professionellen GIS-Werkzeugen. Im Kartenbereich haben Produkte wie TileMill oder D3.js, sowie Dienste wie CartoDB, GeoCommons, usw. den Anwenderkreis weit über das klassische GIS-Fachbebiet hinaus erweitert. Im Vortrag werden einige herausragende Beispiele vorgestellt und deren Relevanz für die Fachwelt erläutert.
