Description: Annual statistics per city block on residential population (by age group) and workplace employees (https://www.basleratlas.ch/ ) are used to derive maps of annual night-time and daytime building-scale population density (inhabitants per m2) for weekdays and weekends. The spatial resampling of the population is based on the assumption of proportionality between building inhabitants and building volume (estimated as mean building height×building plan area, derived by land cover and DSM products). Considering the building type, building volume is separated to residential volume and workplace volume, so that population is redistributed between night-time, daytime, workdays and weekends.
