Urban vegetation is a key element in enhancing the quality of life for urban residents and maintaining ecological balance. Serving as a vital component of the urban landscape and ecosystem, it is instrumental in ecological processes such as biodiversity conservation, air purification, carbon sequestration, and water management.

Furthermore, urban vegetation contributes significantly to the promotion of human health and both individual and collective well-being. It facilitates thermal comfort, regulates pollutants, fosters social cohesion, provides recreational spaces, and boosts tourism.

Nevertheless, municipalities often lack comprehensive information about their vegetal heritage and its impact on population well-being, particularly concerning thermal comfort. Addressing this information gap, TerraNIS developed Langdia several years ago (ex Greencity), with the aim of tackling the ecological transition challenge in cities and overcoming this barrier.
