Hi!

I've created a library to help with GPS enabled applications. Available here:

http://www.esenthel.com/?id=store&item=154

Features:

• Easily import and draw a tiled map.
• Link location to map position (moves map when you walk)
• 'Unlock' function to show off your app when you're not on the right location
• Scale map and all overlays (zoom by pinch or mouse wheel)
• Convert between map and GPS positions, calculate distances
• Add map overlays (circles, clickable icons, shapes and routes)
• Devtool to help you check gps locations
• Import KML files from mymaps.google.com
  

Cheers!

Can i dynamically stream gps world map using this library like EE does when streaming worlds?
Or am I limited to map size which i set in init method?

Yeah, you're limited to that. I've never needed to include a map of a very large area, so it wasn't needed.

At any rate, if you use very big maps they will need lots of data. It might be easier to write a wrapper around MapBox and use online maps.

Yes, for mobile games like Ingress

That is certainly not what i had in mind. I'm working on small projects were an interactive overlay has to be created for sound art in a park, an open air museum catalog and such.

Of course if you would like to implement such in EE, you can still borrow some of my code. The gps parts and kml imports will be useful, but you need another way to download and draw map parts.
