OpenStreetMap is a mapping project that aims to build a free and geographical database of the world. Following the consequences of global warming that the world is facing today through natural disasters, OSM, in addition to being a database development project, is also a tool for environmental awareness and management. By mapping urban areas (buildings, roads, points of interest) and rural or peri-urban areas where vegetation is important, this project can also be a tool to combat urban heat islands. This is done through the MapATI project, which means mapping trees or green space.
