Global Google-Microsoft Open Buildings Dataset

This dataset consolidates Google's V3 Open Buildings and Microsoft's most recent Building Footprints, comprising a staggering 2,534,595,270 footprints. As of September 2023, it stands out as the most comprehensive openly accessible dataset. Encompassing 92% of Level 0 administrative boundaries, the dataset is organized into 182 partitions. Each footprint is explicitly labeled with its origin, denoting whether it is from Google or Microsoft. Accessible in cloud-native geospatial formats such as GeoParquet, FlatGeobuf, and PMTiles, this dataset provides a robust resource for various applications. Further details, including the dataset's comprehensive information and methodology, can be explored here and here, respectively.

Dataset Schema

Country level datasets were inegsted while each row in the dataset provides information on a specific building footprint with associated information on individual columns

  • boundary_id (INTEGER): A unique ID linking the CGAZ level 0 boundary ISO to an integer, created for partitioning the datasets within BigQuery.
  • confidence (FLOAT): A metric denoting the model's confidence about the accuracy of the building footprint. Microsoft-sourced footprints set this column to null since the original dataset doesn't feature this attribute.
  • bf_source (STRING): Indicates the footprint's origin - Google or Microsoft.
  • area_in_meters (FLOAT): Represents the polygon's area in square meters.

Earth Engine Snippet

The datasets were collected from the country level geoparquet files and only a subset of these are mentioned below while an earthengine ls should provide more information on all countries ingested. All feature collections are in the format

projects/sat-io/open-datasets/VIDA_COMBINED/"3 letter country ISO code"

for example India would be

var ind = ee.FeatureCollection("projects/sat-io/open-datasets/VIDA_COMBINED/IND")
