The island of Corsica constitutes a microcosm (or microcontinent) characterized by a high heterogeneity of topography and land covers. A large-scale temporal dynamical data base of land use, land cover and phenomena modifying land cover (buildings, fire spread, etc.) of Corsica can be used to experiment complex models. Three centuries of data are updated regularly in three sub-packages called Tempus (XVIII, XIX, XX and XXI).
