I’m working with the we-travel project of a routable J2ME application. For the maps it would be usefull if users could compile the area they need on their own. Therefore, I would like to implement an interface that allows downloading chuncks of the precompiled maps as needed.
Thanks a lot.
For examples I recommend the vector drawing examples of OpenLayers. You can ask further questions here or join the Dutch IRC channel (I assume you speak Dutch/Vlaams?).
