Calculation of a nighttime-population map based on free data

Resumé

When the first authoritative data was released, free access was given to registries like the building registry (BBR). However, statistical data like the nighttime-population is still not free. This analysis shows how we can use dasymetric mapping to dis-aggregate municipality population data into BBR housing units, producing an estimated nighttime-population map. The results produced show that the proposed model has a general overrepresentation of the population, but despite that, this free dataset calculated here, should be usable in many cases where an estimate is adequate.
