Geospatial data of the building stock is essential in many domains pertaining to built environment. These datasets are often provided by governments, but crowdsourcing them has surged last decade. Nowadays, OpenStreetMap (OSM) – most popular Volunteered Geographic Information (VGI) platform contains geospatial and descriptive on more than 500 million buildings worldwide collected millions contributors, it increasingly used studies ranging from energy microclimate urban planning life cycle assessment. However, large-scale understanding their quality remains limited, which may hinder use management. In this paper, we seek understand state information OSM whether a reliable source such data. We provide comprehensive study assess attribute (descriptive) mapped globally, e.g. function, key ingredients analyses simulations examine three aspects: completeness, consistency, accuracy. assessment, first at scale available hitherto, find that continues be highly heterogeneous — poor some, very high completeness other areas, potentially benefiting range application domains, estimate 3D models 443 administrative units (mostly cities municipalities) around world can generated OSM, underpinning generation digital twins. The number floors type frequent properties contributors record, cases accurate, while mapping interior did not gain momentum.

Abstract. Heat waves (HWs) and cold (CWs) can have considerable impact on people. Mapping risks of extreme temperature at local scale, accounting for the interactions between hazard, exposure, vulnerability, remains a challenging task. In this study, we quantify from HWs CWs Trentino-Alto Adige region Italy 1980 to 2018 high spatial resolution. We use Wave Magnitude Index daily (HWMId) Cold (CWMId) as hazard indicators. To obtain CW risk maps combined following: (i) occurrence probability obtained using zero-inflated Tweedie distribution (accounting directly absence events certain years), (ii) normalized population density maps, (iii) vulnerability based eight socioeconomic The methodology allowed us disentangle contributions each component relative total change in risk. find statistically significant increase HW while remained stagnant analyzed area over study period. A decrease spells is observed through except larger cities where increased. increased 40 % region, with being greatest highly populated areas. Stagnant declining result reduced levels overall, four main exposure levels. These findings help steer investments mitigation, method potentially be applied other regions there are sufficient detailed data.
