Overview

This project contains useful info/tools for processing OSM maps into the mapwriter file format (.map)

Manual Procedure

Setup osmosis in a directory (unzip release -- ZIPBOMB ALERT!!!!)
Create plugins directory under osmosis
Move mapsforge release jar to osmosis/lib/default/
Decompress maps (if they were previously compressed)
./osmosis bin/osmosis --rb file=../maps/a_map.osm.pbf --mapfile-writer file=../maps/a_map.map -* If you run out of heap space add JAVACMD_OPTIONS="-Xmx16g" to the start of the line -* If increasing the heap doesn't work, append type=hd to end of command -* You can merge maps using --merge passed to osmosis (before --mapfile-writer) using n-1 instances of --merge where n is the number of --rb or --rx options passed

Used to generate above info
