Investigating the digital divide in OpenStreetMap: spatio-temporal analysis of inequalities in global urban building completeness, 26 August 2022, PREPRINT (Version 1) available at Research Square [https://doi.org/10.21203/rs.3.rs-1913150/v1](https://doi.org/10.21203/rs.3.rs-1913150/v1)\n\n\u003e OpenStreetMap (OSM) has evolved as a popular geospatial dataset for global studies, such as monitoring progress towards the Sustainable Development Goals.\nHowever, many global applications turn a blind eye on its uneven spatial coverage.\nWe utilized a regression model to infer OSM building completeness within 13,189 urban agglomerations.\nFor 1,848 cities (16% of the global urban population) OSM building footprint data exceeds 80% completeness, but completeness remains lower than 20% for 9,163 cities (48% of the global urban population).\nFrom 2008-2023 inequalities in OSM have receded, but a strong spatial bias associated with subnational human development index (SHDI), city size and World Bank region remains.\nHumanitarian mapping efforts have significantly improved completeness, especially In low SHDI regions, \nKnowing the biases in OSM's coverage enables researchers and practitioners to provide clear recommendations for decision makers, as they now can properly account for the previously “invisible” missing data.\n\nHere we provide the python code and data for reproducing the analysis and figures presented in the global urban OSM building completeness analysis manuscript. Several jupyter notebooks and additional scripts are provided to pre-process the data.\n\n\n## Data\nMake sure to download geopackage data from Figshare: https://doi.org/10.6084/m9.figshare.22217038\n\nYou can also interactively explore the results in [ohsomeHex](https://hex.ohsome.org/#/urban_building_completeness/2022-01-01T00:00:00Z/2/29.21752531472042/16.251362043911197).\n[![name](figures/ohsome_hex_screenshot.png)](https://hex.ohsome.org/#/urban_building_completeness/2022-01-01T00:00:00Z/2/29.21752531472042/16.251362043911197)\n\n\n## Create Figures, Maps and Tables\n### Figures and Analyses\nThe processing steps for the analyses can be found in the `notebooks` section.
