What is OpenStreetMap?

OpenStreetMap (OSM) is a collaborative project to create a free and editable map of the world. Unlike proprietary map data from companies like Google or Apple, OSM map data is open and licensed under the Open Database License (ODbL), which allows anyone to use, modify, and distribute the data freely.

The OSM database contains geographical data such as streets, buildings, natural features, and more. This vector data can visualize maps with features like roads, land use areas, elevation contours, political boundaries, and points of interest. The database is built and maintained by a global community of mappers who contribute and update data using aerial imagery, GPS tracks, local knowledge, and field surveys.

Some key advantages of OpenStreetMap over other mapping platforms include the following:

• Free to use and share - No restrictive or expensive licensing
• Very detailed maps - Millions of points of interest and roads in OSM database
• Frequently updated - Thousands of improvements daily by OSM editors
• Customizable - Data can be modified and styled as needed
• Community-driven platform - Created by and for the users

The OSM database can power a wide variety of mapping applications. Websites like OpenStreetMap.org provide tile maps using OSM data. Developers can also build custom maps, routing services, geospatial analysis tools, and more powered by OSM data. Major companies like Apple, Facebook, Microsoft, and Wikipedia all use OpenStreetMap data in their own maps and services.
