I am a spatial data scientist, open source GIS advocate, and author. This blog was born in 2010 as a place to record my thoughts and experiences in using open source GIS.

My background is in information technology with a specialization in geographic information science and I am currently working with the Center for Mobility Systems at the Austrian Institute of Technology in Vienna. I am teaching QGIS classes at UNIGIS Salzburg and serve on the QGIS project steering committee. From 2015 to 2017, I served on the OSGeo board of directors.

I have published several books about QGIS, including “Learning QGIS” (currently 3rd edition), “QGIS Map Design”, and “QGIS 2 Cookbook”. Furthermore, I develop tools such as Time Manager and pgRoutingLayer plugin for QGIS.
