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.

For build instructions and to contribute, please see the contributing guidelines.

• A uni-directional navigable network (Edge, Node)
• Non-navigable features (Area, Line, Point, Relation)
• All tags

As well as other handy tools:

• Create it from .osm.pbf
• Sharding
• Shard Stitching
• Shard Exploration
• Tag Filtering
• Atlas Filtering
• PBF Ingest
• Country Slicing
• Way Sectioning
• Cutting
• Routing
• Higher-level entities
• Saving / Loading
• GeoJSON Parser
• Command Line Tools
• Atlas Query Language i.e. AQL
