OpenStreetMap is a free street level map of the world, created by an ever growing community of mappers. Get started by learning about how to edit OpenStreetMap or using the many tools available to edit or use OSM data. Check out the resources available within LearnOSM or the HOT Training Center.
Plan a Mapping Campaign
If you are intersted starting a remote or field mapping campaign, you can get started by finding available imagery to use via OpenAerialMap, plan a remote mapping campaign via the Tasking Manager, or set up and track a field campaign with MapCampaigner.
Edit the Map
Quickly get started with editing and contibuting to OpenStreetMap via the Tasking Manager. You can volunteer your time to active mapping projects and support organizations in need of map data around the world. Check out OpenMapKit or Maps.me for field based editing of OpenStreetMap.
Get OSM Data
To access OSM data, HOT built the Export Tool which allows anyone to create custom extracts of OSM based on the area and type of data you want to access. Export Tool allows you to save, rerun, and share OSM data.
To understand more about how and when editing took place, or assess quality within OSM, use the OSM Analytics suite of tools. You can view how data has changed over time within OSM, understand quality within an area, or analyze what type of data is available.
