Overview
=
This project contains useful info/tools for processing OSM maps into the mapwriter file format (.map). It was developed to help generating offline map files for Locus on Android.

Dependencies / Prereqs
=
To run this program you'll need the following

* A Linux environment
* Python 3.x installed
* Java 1.8 or higher installed (OpenJDK works)
* wget installed
* bunzip2 installed (usually part of bzip2 package)

Installation
=
Head over to releases tab and download the latest. Extract the file and you're good to go. Everything is self-contained minus the above dependencies.

Running
=
To run the program, cd to the directory where you extracted the release and run './process_maps.py' with at least one '--map-list /path/to/list.txt parameter'. See the lists directory for examples on how to format the map list files.

Program Usage
=
```
usage: process_maps.py [-h] [--map-list MAP_LIST] [--no-sleep] [--use-ram]

optional arguments:
  -h, --help           show this help message and exit
  --map-list MAP_LIST  a text file with one map URL per line, can be specified
                       more than once
  --no-sleep           don't sleep between downloads -- WARNING you can easily
                       run into throttling on mirrors if you use this option
  --use-ram            use RAM for mapsforge processing -- WARNING mapsforge
                       uses 10x the map size in RAM for processing (ie. 100Mb
                       map = 1Gb RAM usage), you want a LOT of RAM for this
                       option
