Hello, I am Martijn van der Putten, also known as Zugführer. I’m a MSc in geo-information science, but above all geocacher, food deliverer and public transport enthusiast.
In the past I have worked on BAG import in several places in the Netherlands as Zugführer_BAG.
I like to walk and cycle around the Netherlands (and far beyond) and will update the map if I notice that’s something is not right or missing.
You can send me a message in Dutch, English or German
