Quality of crowdsourced geospatial building information: A global assessment of OpenStreetMap attributes

Building and Environment, Journal Year: 2023, Volume and Issue: 237, P. 110295 - 110295

Published: April 18, 2023

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.

EUBUCCO v0.1: European building stock characteristics in a common and open database for 200+ million individual buildings

Scientific Data, Journal Year: 2023, Volume and Issue: 10(1)

Published: March 20, 2023

Building stock management is becoming a global societal and political issue, inter alia because of growing sustainability concerns. Comprehensive openly accessible building data can enable impactful research exploring the most effective policy options. In Europe, efforts from citizen governments generated numerous relevant datasets but these are fragmented heterogeneous, thus hindering their usability. Here, we present EUBUCCO v0.1, database individual footprints for ~202 million buildings across 27 European Union countries Switzerland. Three main attributes - height, construction year type included respectively 73%, 24% 46% buildings. We identify, collect harmonize 50 open government OpenStreetMap, perform extensive validation analyses to assess quality, consistency completeness in every country. v0.1 provides basis high-resolution urban studies scales continental, comparative or local using centralized source variety use cases, e.g., energy system analysis natural hazard risk assessments.

Assessing OSM building completeness for almost 13,000 cities globally

International Journal of Digital Earth, Journal Year: 2022, Volume and Issue: 15(1), P. 2400 - 2421

Published: Dec. 19, 2022

OpenStreetMap (OSM) is an essential source for acquiring building data, although such data may suffer from quality issues. Many studies have focused on assessing OSM but few been carried out a global scale. This study aims to assess completeness (a measure) 12,975 cities across the globe. was achieved by employing population grid as proxy reference data. Not only of each city also that grids within assessed. The assessment results were evaluated based calculating overall accuracy and r-square value between estimated values. Results showed 75% cities, lower than 20%; no more 9% higher 80%. accuracies most countries highly correlated with completeness, which verifies effectiveness our approach. These be useful updating in OSM. A open dataset related has made available public use.
