I have a mobile map application. I have found that directly accessing the
tile server works the best. Trying to draw all the map details at runtime
on a PDA is a bit much. It can be done, but pre-cooked tile are much
The main use I would have for the mobile API would be for place name lookup
and a routing network. At the moment neither of those exist in a usable
On the note of mobile applications. I think it would be useful to create a
DB of cellID's. CellID's could be collected from PDA phones with a GPS
attached. With the CellId, someone without a GPS could get their
approximate location on the map.
It is a bit like doing tracks. For each CellId there will be many lan/lon
recorded values. It doesn't make much sense to dirty the normal database
with these. Instead they would need to be processed and turned into a
single point or maybe even an area.

In this regard: Are others looking into tiles for mobile?
We develop a mobile application (in J2ME) that uses OSM tiles.
And while I would support the binary protocol, currently we retrieve
resized tiles (because drawing vectors isn't exactly easy).
We have done a bit of optimalilsation, but sofar just stick with resized
Have others been doing things like this?
