Short Announcement: QGIS 2.8 Wien released

QGIS 2.8 (the new “Long Term Release”) was released a few days ago. It is a minor release according to the changelog but it will be supported in this setup at least for the next year: Some good news for all those working in a bigger, administrated environment as it is always a problem to update software in these bigger infrastructures. New features: >1000 issues flagged by static analysis tools fixed new code commits and pull requests are now automatically tests against our testing framework. more responsive browser support for contextual WMS legend graphics custom prefixes for joins creation of…

QGIS 2.6 – Sneak Peak

The release of QGIS 2.6 is planned for October 24, but you don’t have to wait to test new functions in development. In this post I’ll look closer on two new features that in my mind will make GIS life easier, even if some improvements should be made with the first of the new features described here.

ArcGIS server vs. Open Source GIS solutions

originally posted from our friends @mappinggis Which program is better suited to serve geographic data on the web? ArcGIS Server form ESRI or open source ? This question is common in mailing lists and GIS-forums. The most consistent answer is that depends on the project. But in this post we will see some numbers to determine which is the best software to develop an application for web mapping:

OpenSource QGIS + PostGIS installation: “the Windows way”

A short time ago I’ve posted an article on the installation of QGIS in combination with a PostGIS database in the background. As we all know, Windows is mostly used as OS on a PC so this is the Windowized version. This is a short summary that sums up the article of a site called Boston GIS. I’ll show you how to install QGIS version 1.8 (which will be updated in some days) and PostgreSQL with PostGIS extension and show you the first steps in the import of shapefiles and raster data.

OpenSource QGIS + PostGIS installation: “the Ubuntu way”

A lot of you out there are probably working on Windows Systems using ArcGIS and I have to admit that the possibilities with ArcINFO in the background and a proper GDB (GeoDataBase) are really big. But let’s be honest: A lot of your tasks are more or less everyday business, right?! So let us have a look on building a GIS workplace using QGIS 1.8 (which will be updated the big way in some days/weeks) and PostGIS which is a spatial enhancement of PostgreSQL.

QGIS Tutorial II: from data to map – preparing data visualisation

In this tutorial I would like to show you, how to create a topographic map and analyse topographical data using freely available SRTM data and QGIS including some data manipulation. This is part one explaining how to get data, remove missing values, explore the relief and changing the color representation of a TIF file obtained by the USGS.
