Overture provides free and open map data

Sourcing and curating high-quality, up-to-date, and comprehensive map data from disparate sources is difficult and expensive.

Overture aims to incorporate map data from multiple sources including Overture Members, civic organizations, and open data sources.

Multiple datasets reference the same real-world entities using their own conventions and vocabulary, making them difficult to merge and combine.

Overture Maps will simplify interoperability by providing a system that links entities from different data sets to the same real-world entities.

Map data is vulnerable to errors and inconsistencies.

Overture Maps data will undergo validation checks to detect map errors, breakage, and vandalism to help ensure that map data can be used in production systems.

Open map data can lack the structure needed to easily build map products.

Overture will define and drive adoption of a common, well-structured, and documented data schema to create an easy-to-use ecosystem of map data.
