Yeah that's the url I'm using. followed you're advice from earlier & found it in an earlier post. another ? if you don't mind. since mm needs internet access 2 pull up any maps, do i need to continue saving the map folders in my docs? using alot of memory. thanks

"http://mt.google.com/mt?n=404&v=ap.6&x=%d&y=%d&zoom=%d"
I guess this was an older URL.

Hello everybody, and thank once more to gnuite for a wonderful app.
two questions:
1. It seems maemo mapper does not work with a proxy server. This is a serious disadvantage, some ppl only see the web through a proxy(including me ofcourse). Maybe it could just respect the $http_proxy var?
2. [irrelevant] How much time did it take you to code this app gnuite? I am very curious.
Thanks a bunch.

It would be nice if we can have areas in a compressed file that are looked at first then the filesystem based cache secondarily.
What would be even better would be a local http daemon that serves the data from a mps file . Fileformats are a pain sometimes

If you are serious about cramming as many maps into your card as possible, you should use ext2 and use hard links to represent map tiles that are "the same data" - water maps are all solid blue, so you can save the additional 103 bytes per tile.
Other map storage mechanisms have been considered and discarded in favor of the RAM and CPU efficiency of using the file system (including adding and removing maps on-the-fly).

The first version took less than 40 hours (a lot of that was spent learning about NMEA and the mercator projection). The remaining hours have been spent making everyone else happy by adding feature requests.

I've been playing with the idea of server. Like said, there is alot of redundant data. I could further subdivide the data and really clean house. Just rebuild the zoom level 0 and server up the rest in the 256x256 blocks.
