Overview

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

Manual Procedure

Prep

• Download updated maps: http://download.geofabrik.de/north-america.html and http://download.geofabrik.de/north-america/canada.html
• Pull latest osmosis from http://wiki.openstreetmap.org/wiki/Osmosis
• Pull latest mapsforge for osmosis from https://github.com/mapsforge/mapsforge/blob/master/docs/Downloads.md

Process maps for device

• 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
