Maps.me / Organic Maps MWM
Price before paymentbetaMWM is the binary offline-map format used by Maps.me and Organic Maps. The file is built by the native Organic Maps generator_tool from a regional extract of the OpenStreetMap planet — the same builder that produces the app's official maps. The build is heavy, so the order goes to the long queue (up to ~95 minutes). The file is built together with a search index and a routing graph, without the coastline and the world overview map. Checked on a device: the .mwm opens in Organic Maps and the map is visible; Maps.me has not been checked.

Key Features
About MWM Format
MWM is the offline map format of the Maps.me and Organic Maps apps. The format is designed to carry vector geometry, search indexes and a routing graph in one file, in the shape the app's engine expects. That is why a map cannot simply be "saved as": it has to be built as a whole, with the same builder Organic Maps use for their own country maps.
We keep that builder and run it on the area you pick. The result is your own area cut from OpenStreetMap: the file is built together with a search index and a routing graph, but without the coastline and the world overview map — the app takes those from its own built-in maps. Checked on a device: the file opens in Organic Maps and the map is visible. The price of a real build is time — the order goes to the long queue and can take up to about 95 minutes, where a plain data export takes seconds.
The point of the format is your own area, in more detail and separate from a ready-made country map: you set exactly the bounds you need, get them as one file and put it on the phone next to the built-in maps.

Who Uses MWM Maps
How to Export MWM
How to Open After Export
- Organic Maps — put the .mwm into the app's maps folder (the subfolder named after the data version date, the same one that holds downloaded maps) and restart the app. The exact path depends on the platform and version — see the Organic Maps help.
- Maps.me — we have not checked opening the file in this app; it is checked in Organic Maps only.
- Open the area in the app and zoom in — the map should be visible. Search and routing on the file have not been checked on a device yet.
- Need the neighbouring area — order it as a separate file: the app holds several maps at once.
