Maps.me / Organic Maps MWM

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.
