[`Atlas`](src/main/java/org/openstreetmap/atlas/geography/atlas/Atlas.java) is a way to efficiently represent [OpenStreetMap](http://www.openstreetmap.org/) 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 `Node`s and `Edge`s 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](https://github.com/osmlab/atlas-generator): A Spark job to distribute Atlas shards generation

* [atlas-checks](https://github.com/osmlab/atlas-checks): A suite of tools to check OSM data integrity using Atlas, and Spark.

* [josm-atlas](https://github.com/osmlab/josm-atlas): A JOSM plugin to visualize Atlas data.

# Getting started
