Map your family tree with Gramps and QGIS – how to digitize and visualize genealogy data

As I realized that I have a really huge family I was keen to digitize the current family tree and get into contact to my relatives. For getting things done, I choose the open source genealogy software Gramps to record all offline information about my family members and create a database as base for further investigations, updates and of course spatial visualization. After that, I exported a database view and visualized it with QGIS.

create 3D visualizations: QGIS, GRASS and NVIZ

3D is soooo cool… Okay let’s be honest: the exciting times of Second Life are gone and the Oculus Rift is still not in sight in the end-user stores. But it is and was always cool to create you own 2.5D (we are using GIS not CAD, you know) visualization and make beautiful graphics for your papers or posters. It was always a big drawback for QGIS that ArcGIS was and is so good with ArcScene. But we’re proud users and we’ll use NVIZ. Let me show you how.

The Spiegel Magazine and their “maps”

Today I stumbled upon a “map” on Spiegel Online ( an import news page in Germany ) which shows the spied countries of the NSA. As we already know leaflet quite good and also tried other mapping possibilities I was interested in what they are using for this map which is more informative than this useless map. So looking on the source code: It’s a library called jvectormap.
