- Abstract summary: We conduct a global study of 2D geospatial data on buildings that are released by governments for free access.
We benchmark more than 140 releases from 28 countries containing above 100 million buildings, based on five dimensions: accessibility, richness, data quality, harmonisation, and relationships with other actors.
We find that much building data released by governments is valuable for spatial analyses, but there are large disparities among them and not all instances are of high quality, harmonised, and rich in descriptive information.

- Abstract: As buildings are central to the social and environmental sustainability of
human settlements, high-quality geospatial data are necessary to support their
management and planning. Authorities around the world are increasingly
collecting and releasing such data openly, but these are mostly disconnected
initiatives, making it challenging for users to fully leverage their potential
for urban sustainability. We conduct a global study of 2D geospatial data on
buildings that are released by governments for free access, ranging from
individual cities to whole countries. We identify and benchmark more than 140
releases from 28 countries containing above 100 million buildings, based on
five dimensions: accessibility, richness, data quality, harmonisation, and
relationships with other actors. We find that much building data released by
governments is valuable for spatial analyses, but there are large disparities
among them and not all instances are of high quality, harmonised, and rich in
descriptive information. Our study also compares authoritative data to
OpenStreetMap, a crowdsourced counterpart, suggesting a mutually beneficial and
complementary relationship.
