The land area in which rebuilding occurred corresponds to the land plots on which a building existing in 2010 was demolished and replaced by a new building by 2016 (regardless of whether it includes dwellings or not), within the residential and the mixed-used areas in the municipalities' general land use plans (PAG). These areas were captured by comparing the orthophoto-images. The data sources are the digitalized cadastral parcels and the orthophoto-images from the "Administration du Cadastre et de la Topographie", as well as the PAG of the municipalities.

The land area used for residential production corresponds to the land plots which were vacant at the beginning of the observation period and on which stood a building at the end of the observation period within the residential and the mixed-used areas in the municipalities' general land use plans (PAG). Thus, only the areas on which a building was constructed (regardless of whether it includes dwellings or not) are taken into account in the land consumption, without considering the plots on which roads, car parks etc. were build. These areas were captured by comparing the orthophoto-images. The data sources are the digitalized cadastral parcels and the orthophoto-images from the "Administration du Cadastre et de la Topographie", as well as the PAG of the municipalities.
