This dataset provides the Numerical Canopy Surface Model (NCM), representing the ground area covered by tree foliage within the Canton of Geneva, Switzerland. It can be used to calculate a canopy index, expressed as a percentage of a territory, to assess the degree of tree cover. The data was derived from LiDAR point clouds acquired in March 2019. It is published by the Système d'information du territoire genevois (Geneva territorial information system) and is freely accessible without authentication, providing a basis for urban greenery and vegetation-cover analysis at the local level.”The Numerical Canopy Surface Model (NCM) represents the floor area covered by tree foliage. This area can be used to calculate the canopy index in % of a territory in order to assess the degree of tree cover. This data was produced from LiDAR point clouds acquired in March 2019 and with a density o…
