Maps for J2ME mobile phones

You can download some interactive maps for mobile phones with J2ME/MIDP (Java 2 Micro Edition) as JAR files. If you want to download the file using 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.

If you want to compile or emulate the software on your PC, you need to download the Java 2 Micro Edition (J2ME) Wireless Toolkit.

Weybridge example map

The map was taken from openstreetmap.org (License: GFDL).

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 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

Afterwards you can create the tiles using the Ruby script 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

Political world map

The map was taken from the The World Factbook (License: public domain).

Visible Earth

The picture was taken from the Visible Earth project (License: public domain).

Munich public transportation map

The map was taken from de.wikipedia.org (License: GFDL).

New York City Subway Map

This NYC subway map originated from www.nycsubway.org (License: public domain).

Sheffield Supertram map

The map was taken from en.wikipedia.org (License: Creative Commons Attribution-ShareAlike 2.0 Canada)

Cambridge multiresolution map

Thanks to the work of the OpenStreetMap 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. The data is subject to the terms and conditions of the Creative Commons Attribution ShareAlike License v. 2.0.

Weybridge multiresolution map

Now there also is a free multiresolution streetmap of Weybridge for J2ME mobile phones. The data is provided by the OpenStreetMap community and subject to the terms and conditions of the Creative Commons Attribution ShareAlike License v. 2.0.
