Atlas

Atlas is a way to efficiently represent OpenStreetMap data in memory. A subset of the data is in a "navigable network" form, meaning anything that is assumed to be navigable will be in a form of Nodes and Edges in a way a routing algorithm could traverse it. It also provides easy to use APIs to access geographical data. On top of it all, it is easy to shard and re-stitch, making it perfect for distributed processing!

Projects using Atlas:

• atlas-generator: A Spark job to distribute Atlas shards generation
• atlas-checks: A suite of tools to check OSM data integrity using Atlas, and Spark.
• josm-atlas: A JOSM plugin to visualize Atlas data.
