Hi, all,
I am looking for some free APIs or library to mashup a mobile navigation
application, and I will use the OSM tile as the base map. I am just using the
free libaray j2memap, But it did not provide such a API that could rotate the
map so that the driver direction is always the north direction! By the way, I
have found that the VGPS software provide the similar function, But it is not
free. I have also tried to rotate the map tile, but this method not only
distorts the map image,but also upside down the road name information when you
rotate the map image by 180 degree. Could anyone help me? Or if there is other
solution to make the driver direction always the north direction? I have been
stucked by this problem for several weeks. So any Suggestion is welcomed.
Please help me! Thanks!
Regards.
