The Overture Maps Foundation, a group founded by Amazon, Meta, Microsoft and TomTom, has released an initial open dataset that will help developers build mapping apps and other location-based tools. The "alpha" set includes worldwide info for over 59 million places, 780 million unique buildings, road data from OpenStreetMap and borders.
The map layers are packaged in a recently-launched Overture map format that's meant to be standardized and interoperable between platforms. The group is mainly sharing the data at this stage to get public feedback, rather than to support complete products.
