Recent Geomob Berlin speaker Dave Whittingham discusses his project Kreuzungen, a website that allows users to upload their GPX tracks and find out which rivers they have crossed. The project started as a fun idea and has now gained popularity. Dave highlights the importance of open data and open-source tools in making the project possible. Kreuzungen serves as an example of learning through experimentation and play in the geospatial community.
