Maps for J2ME mobile phones

You can download some interactive maps for mobile phones with J2ME/MIDP (Java 2 Micro Edition) as JAR (https://en.wikipedia.org/wiki/JAR_%28file_format%29) files. If you want to download the file using GPRS (https://en.wikipedia.org/wiki/GPRS) you have to use the link to the JAD file instead. Please refer to your mobile-phone's manual on how to install Java programs. E-mail me, if you find a bug in the software.

The size of each software package is mentioned. Note, that temporarily you will need twice as much memory on your mobile, because the JAR-file will only be deleted after installation. You can put comments and submit ratings at getjar.com (https://www.getjar.net/products/4729/VerkehrsnetzMuenchen).

If you want to compile or emulate the software on your PC, you need to download the Java 2 Micro Edition (J2ME) Wireless Toolkit (https://java.sun.com/products/sjwtoolkit/download-2_2.html).

Weybridge example map

The map was taken from openstreetmap.org (https://wiki.openstreetmap.org/index.php/Neat_Stuff) (License: GFDL (https://www.gnu.org/copyleft/fdl.html)).

  • MobiNav.jar (https://www.wedesoft.demon.co.uk/downloads/MobiNav.jar) (191 kByte) Java archive
  • MobiNav.jad (https://www.wedesoft.demon.co.uk/downloads/MobiNav.jad) description file
  • MobiNav.tar.gz (https://www.wedesoft.demon.co.uk/downloads/MobiNav.tar.gz) (176 kByte) source code and map-tiles (license: GPL (https://www.gnu.org/copyleft/gpl.html))
  • splitmap.rb (https://www.wedesoft.demon.co.uk/downloads/splitmap.rb) (638 bytes) source code of Ruby script for splitting up an input file into map-tiles (requires HornetsEye)

Note, that for creating map-tiles yourself you need to provide maps for several resolutions (multiresolution pyramid). If you don't have a multiresolution map, you need to scale the input image down to 50% multiple times. You can use the command-line tool convert which is part of ImageMagick (https://www.imagemagick.org/) to do this:

convert map.png -scale 50%% map2.png
convert map2.png -scale 50%% map3.png
convert map3.png -scale 50%% map4.png
convert map4.png -scale 50%% map5.png
convert map5.png -scale 50%% map6.png

Note that each dimension of the last pyramid level (here: map6.png) must not be bigger than the tile size (here: 128)! Afterwards you can create the tiles using the Ruby script splitmap.rb (https://www.wedesoft.demon.co.uk/downloads/splitmap.rb):

./splitmap.rb map.png 128 5
./splitmap.rb map2.png 128 4
./splitmap.rb map3.png 128 3
./splitmap.rb map4.png 128 2
./splitmap.rb map5.png 128 1
./splitmap.rb map6.png 128 0

It is also recommended to compress the resulting map tiles by reducing the number of colours (no dithering!). To do this move the map-tiles into an empty directory and compress the map tiles as follows:

mkdir targets
for i in *.png; do convert $i -depth 8 -colors 32 +dither target/$i; done

Cambridge multiresolution map

Thanks to the work of the OpenStreetMap (https://www.openstreetmap.org/) community it is now possible to create free multiresolution streetmaps for mobile phones! Free multiresolution maps is a valuable addition to the worlds inventory of free data.
