Did so: //https://getsatisfaction.com/locus/topics/display_nearby_pois_from_osm_maps_in_a_list

Let's assume I stand in the middle of a foreign city and look for a restaurant.  I have opened Locus with an OSM-generated vector map.  I'd like to see a list with all restaurants which are marked as such on the OSM map, in order of their distance from my current location.

Is this possible in Locus?  If not, how do I get close to it?  How do you solve this usecase?

[...]Thank you for the links!  However, they suggest there is a file size limit of 2GB.  This is not the case, it is 4 GB.  Thus, it is not an Android problem. I suspect a bug or limitation in mapsforge.

I stand corrected.  Apparently, Android <3.0 has problems with accessing arbitrary positions in a file larger than 2GiB.  This has been fixed in Android 3.0.

I believe there is no way. I have 2 RMaps with about 3,9 GB each. Both worked in the past with WinCE 5 TWoNav system.
Now, just tested with my S2 with SanDisk MicroSDXC 64GB I can see the maps with root explorer, but not open with Locus or Oruxmap.

You may test the map possibly with other tools here: //https://bob.ipv.kfa-juelich.de/bronger/west_europe.osm.map.xz

bronger, I really suggest to separate your map to smaller parts.[...]

I will do so.

On the other hand, I also really want to have more than one country in a map.  I live in Aachen, Germany, with three countries within a range of 10 km.    I think on the long run, Locus/mapsforge should be able to handle such maps.  Crossing borders while navigating into the holidays is a common usecase, and people expect this to work seamlessly.  Moreover, creating such maps will become more and more feasible with modern hardware.

See //http://code.google.com/p/mapsforge/issues/detail?id=301.

[...] If you created such huge map, please test it with AdvancedMapViewer here http://code.google.com/p/mapsforge/ (section download). If result will be same, then it's a problem of MapsForge and should be reported on their site. [...]

The AMV cannot display the map either: "Value too large for defined data type".  Well, mapsforge's own code generated that map.    Anyway, I'll take the discussion to their site.  What a pity, it was so difficult to make the map ...

I think it's global limitation on whatever file size - 2GB

But the file is there -- I can see it with its full filesize with other apps on my smartphone.  It's just that Locus ignores it.  I think 4GB is the limit of the file system.  So is it a bug in Locus?

Is there a maximum size for vecor maps?  I have a western Europe .map file in my mapsVector/ directory, yet Locus doesn't dislay it in the map selection menu.  Its size is 3.3 GB.

Can one test easily whether a .map file is valid?
