At Saturday the 23rd of March 2019, it was time again for very young researchers being introduced to GIScience. Melanie Eckle, Martin Hilljegerdes, Sven Lautenbach, Katharina Przybill, Leonie Schuchardt and Vivien Zahs introduced 16 highly motivated kids into GIScience as part of the KinderUni 2019. After an overview and an introduction into desktop mapping and how to help in humanitarian mapping with MapSwipe, we went out for a scavenger hunt. The kids navigated the Neuenheimer Feld based on absolute and relative coordinates using maps and GPS receivers to locate the treasure – but this year’s highlight was the “group picture” taken by a laser scanner in front of the famous Hettner rock, which allowed to measure the kids’ height with high precision. A screenshot of the point cloud together with a traditional group picture with the rabbits before the physics building and a self created uMap with all relevant events along the route will remind young participants of their first GIScience contact – maybe in the not so far future we will see some of them again as students, scientist and professors at GIScience.
