I have found solution for converting OSM file into .map file but is there a way for converting .map file back to osm or shp or any other well-known vector file type?

by .map file i mean mapsforge .map file, not mapinfo .map file

  • Is the .map file a MapInfo binary? If so you can use ogr2ogr to convert it to pretty much anything.

  • Maybe there is a different solution to your problem. Can you tell us the reason why you want to convert the map back into OSM's format?

  • i want to extract polylines coordinates from that file. I think it is possible using official mapsforge library and some coding, but i was seeking for a more straightforward solution.

  • But why don't you extract this kind of information from OSM in the first place? Isn't your mapsforge map file based on OSM data?

1 Answer 1


reading the mapsforge-dev mailinglist for a long time now, I never came accross such a conversion feature.

I assume that OSM data -> mapsforge mapfiles is a oneway processing.

But you can try to ask on your own there, see https://groups.google.com/forum/#!forum/mapsforge-dev

(I only found one similar question there from 2013, but no answer.)
