Improving an off-line mobile GPS navigation system

Dear bidders,

We are looking for help to adjust a program in Java (J2ME CLDC).

What we have:

We're implementing an off-line mobile GPS navigation system based on an existed system called GPSMID at [url removed, login to view]

Our version is customized to work with off-line and large local file on the mobile handset due to the limitation of the execution file size. The local file could extend to hundreds of MB to cover the whole country data.

What we need help in this project:

Improving the speed of loading the vector data of the map from the large local file and showing the map on the handset screen so that the map could be seen immediately or so at a given coordinate or after zooming and panning the map. This should work fast in phones like E50.

All source code of the related modules will be hand over to the winning bidder.

Thanks and looking forward to your bidding.
