Estimation of population.
Once we have estimated the number of buildings we can also estimate the population per mapping unit. We have to assume a number of people per building, which depends on the landuse type, as office buildings have more population than single houses. This information is already provided in the table Landuse. We can also calculate the population for a daytime and a nighttime scenario. For that we have also added two columns indicating the percentage of population that would be present in each type of building during the day and during the night.
