I've installed Viewranger onto to my new Samsung phone and it works fine. However the downloaded OSM maps from the VR website appear to be raster scans (like standard OS maps) rather than vector graphics. The maps files are huge ie 0.5 GB for Hampshire!! Is it correct that VR only runs raster maps? I read somewhere that OSM maps needed conversion to run on VR.
By comparison OSMand does run vector maps and the files are much smaller ie 150MB for SE England. However I cannot persuade the app to show locations as British grid references only as longitude and latitude.
Does anyone know how to fix this?
In both cases the free version of the apps is being used.
Alternatively, does anyone know an app that displays location as grid references and uses OSM vector maps?
