- The Grelou model presents a new methodology for assessing recreation services by utilizing GPS tracks from crowd-sourced data, focusing on integration and spatialization of cultural ecosystem services in the Grenoble area.
- GPS data allowed for precise mapping of visitor networks for ten recreation activities, revealing the spatial distribution of recreation hotspots, such as indoor and outdoor leisure locations.
- An online survey confirmed that local visitation patterns correlated well with Grelou outputs, offering insights into visitor preferences and highlighting the strengths and weaknesses of existing recreation models like InVEST.
