Linux Foundation overTure maps foundation , aimed at creating a neutral and not dependent on the joint development of tools and unified storage scheme of cartographic data, as well as maintaining the collection of open cards, which can be used in its own cartographic services. The founders of the project included Amazon Web Services (AWS), Meta, Microsoft and Tomtom.
Data will apply to the copy of the pale of odbl (Open Database Liceance, is used to in the OpenStreetmap project) and under the permissive license CDLA (Community Data License Agreement, designed for data at Linux Foundation). Licenses are designed specifically for the distribution of databases and compared to Creative Commons licenses take into account a number of legal subtleties and nuances associated with mixing data from various sources and abstracting the structure of the database to maintain the conditions of licensing when changing the structure or order of records. The initial texts of the Overture Maps tools will be delivered under the MIT license.
The difference between the new project and OpenStreetmap boils down to the fact that OpenStreetMap is a community on the creation and editing of cards, while Overture Maps is aimed at aggregation of existing open cards from various sources, including cards prepared in OpenStreetMap and cards, which various companies and organizations are ready to share. At the same time, since both projects use the same license, Overture Maps achievements can be transferred to OpenStreetmap, moreover, Overture Maps participants intend to directly participate in the development of OpenStreetmap.
included in the Overture Maps collection, data will be checked for compliance with reality, possible errors and inaccuracies will be detected. Data will also be updated to reflect changes that occur in reality. To disseminate data, a unified storage scheme will be determined, ensuring the tolerance of information. To bind the same real objects intersecting in different data sets, a unified link system will be proposed.
In the first version of the map of cards from Overture Maps, the publication of which is scheduled for the first half of 2023, it is planned to include only basic layers, including information about buildings, roads and administrative units. In further issues, accuracy and coverage will increase, as well as new layers, for example, with information about interesting places, routes and 3D representative offers.
