Glaciers are among the most reliable indicators of climate change. They are also important ecosystems, providing fresh water and hydroelectric power. Therefore, our model aims to tackle climate change, as well as providing information for water and energy management. During their glacier trip, tourists can join a global expedition to study glaciers, by uploading their photos complete with GPS coordinates (taken through their smartphone) of different glacier spots including the glacier front, edges, crevices, rockfall, landslides and calving. These photos are useful to space agencies and researchers to validate the accuracy of satellite-based data models. Moreover, combined with earth observation satellite imagery, they can improve current water runoff models.
