XGeoTiles: Tiling watersheds with hexagons for serious games

Serious games on water governance at bring people on a particular question together such that they may overcome traditional positions and to trigger positive changes in both representation and behavior. To play with simplied but realistic watershed char- acteristics, we propose the XGeoTiles framework for the description of watershed ele- vation. It comes in the form of a 3D game board that is divided into hexagonal tiles (2D) and prisms (3D). Additional information such as land cover or stream network is also accounted. Provided with a digital elevation model, land cover data and an outlet, the soft- ware returns a hexagonal model and a 3D OpenSCAD model that can be printed on appropriate devices. As an illustration, the hexagonal tiling is applied to a slightly undulating watershed. Results conrm a good representation of the hydrological and landscape properties when a relevant tile size is used.

Serious games on water governance at bring people on a particular question together such that they may overcome traditional positions and to trigger positive changes in both representation and behavior.

Provided with a digital elevation model, land cover data and an outlet, the software returns a hexagonal model and a 3D OpenSCAD model that can be printed on appropriate devices.
