Daylight Map Distribution: A Validated Global OpenStreetMap Subset

Daylight is a complete distribution of global, open map data, containing a validated subset of the OpenStreetMap database. Meta combines the work of global contributors with quality checks from mapping partners to create a free, stable, and easy-to-use street-scale global map. The Daylight Earth Table classifies OpenStreetMap-style tags into a 3-level ontology (theme, class, subclass).

Use Cases

• Rendering global street-scale maps based on the validated subset of OpenStreetMap features.
• Performing large-scale geospatial queries on AWS Athena using the optimized parquet formats.
• Analyzing map feature classification using the 3-level ontology from the Daylight Earth Table.
• Developing disaster response applications based on the stable, community-validated global map data.

Strengths

• Contains a validated subset of OpenStreetMap data with quality and consistency checks.
• Available in multiple formats, including parquet optimized for AWS Athena.
• Daylight OSM Features contains nearly 1 billion renderable OSM features.
• Daylight OSM Elements contains all of OSM, including all 7 billion nodes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for specific feature tables is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
