Timelapse of buildings in Roskilde (BBR, QGIS)

This is an animation of buildings in the Roskilde area in Denmark. BBR Data is downloaded from Dataforsyningen:

Afterwards the data is imported into QGIS and using the temporal control layer on the dateOfConstruction_dateOfEvent_anyPoint field. A little data massage was needed due to lots of buildings with a date of construction in the year 1000 (about 10 % of all data; probably just a code for "A long time ago") or having a non-integer value. Demolished buildings are not included in the data set meaning only current buildings are included.
