OpenSuperMaps is an open-source project focused on improving offline map address search. It combines open address data from OpenAddresses with map data from OpenStreetMap (OSM) to generate enhanced offline map files optimized for the OSMAnd app, addressing the lack of address information in native OSM data for certain countries and regions.
In terms of features and use cases, the project’s core value is “address enhancement,” making it easier for users to search for specific addresses while offline. For supported languages/frameworks, it is not tied to any particular programming language; instead, it directly provides map files that can be read by OSMAnd. The project is fully open source, follows the ODBL 1.0 license, and provides a Github Repo, allowing users to download files for self-hosting or further processing. Its integration and ecosystem are tightly bound to OSMAnd, with data sources based on GeoFabrik and OpenAddresses. However, the project does not provide an API/SDK and only supports static file downloads. The documentation quality is fairly basic, offering only an FAQ for common operations and known issues, with limited in-depth technical implementation documentation.
The project is completely free. Its advantages include being free and open source, receiving regular monthly updates, and significantly improving address search coverage. The drawbacks are also fairly clear: because OA and OSM data are not fully deduplicated, duplicate addresses may appear in search results, such as abbreviated and fully spelled-out versions. In addition, searches must strictly use abbreviated formats, such as “st” rather than “street,” which creates a learning curve.
This tool is suitable for heavy OSMAnd users, outdoor navigation enthusiasts, and GIS data researchers. Current map coverage is mainly focused on Europe and North America, with no China data. Network accessibility from China is unknown, and there are no payment barriers. Alternatives include native OSMAnd maps or standard extracts provided by GeoFabrik.
