Hi!

The OpenStreetMap support in Roassal works pretty well�� The easiest way to start is probably take the latest version of Moose. Open the example browser and look for OpenStreetMap Integration.

Thierry, although pretty cool, I have the impression the integration could be better. Here is a wish list:
�� - Tile caching

This one is working! Ok, ��with latency issues, but we don't know where they are (with Sven, we suspected they were not in the caching code).

��

�� - Predictive zoom level. E.g., If I click twice on the zoomin button, it is likely that I will click a third time. So preloading the needed tile would be good

Sure. There is also the idea of preloading around the current view so that you can drag left or right without delay. But at one point, you look at the code complexity and you say... hum, is that really worth it?

��

Again Thierry and Onil, thanks for this working piece of work. This is fantastic!

The only true weakness we have is to have to go javascript to use it as a web interface :(

Thierry

��

Cheers,
Alexandre
