DESCRIPTION:The built environment is\, globally speaking\, the largest unkn
 own in the understanding of the effects of disasters and in assessing thei
 r risk. Detailed knowledge of it is necessary for many tasks in disaster r
 isk reduction but also in other fields\, e.g. climate-related sustainabili
 ty\, urban planning and management\, insurance and re-insurance. While in 
 well-regulated countries cadastral data is available that provides various
  details about the buildings\, in parts of the world such information is l
 acking and not even the locations of buildings and settlements are known t
 o the authorities. Buildings\, the core part of the built environment\, ca
 n be strongly mixed within small areas in their structural types\, sizes\,
  shapes and number of people in them and the socio-economic structure can 
 vary highly on these scales. This heterogeneity cannot adequately be descr
 ibed by classical exposure models that provide aggregated building data ov
 er larger areas.\n\nA model that describes the built environment on the sc
 ale of each single building has never been accomplished\, nor that such a 
 model is dynamic\, constantly updating with every change of the input data
 . Here\, we present a high-resolution\, open\, and dynamic exposure model 
 with the aim to provide global exposure data on the building level. This m
 odel is based on volunteered geographic information\, predominantly OpenSt
 reetMap and open data that is created with earth observation and machine l
 earning\, e.g. the building footprints of the Google Open Buildings and Mi
 crosoft ML Building Footprints\, and the Global Human Settlement Layer to 
 estimate the extent of built area. The different structural types of build
 ings per region are taken from open aggregated exposure models or develope
 d from cadastral data. It covers every country and territory globally and 
 is to a large degree building complete with approx. 2.7 billion buildings 
 described in detail.
