GISos is a blog about GIS open source solutions. I am a geoecology graduate by education and work since 2015 for the German Federal Institute of Hydrology (BfG) in Koblenz. My field of research is time series analysis and water balance modelling. I use mainly open source software and programming languages, like Linux, R/Shiny, Python, C++, QGIS… As my mother tongue is german, I apologize for language mistakes and also might sometimes switch to German..
