Recently I've been started to get curious about mobile development, specially Geolocation applications, how do they work and stuff... Can anyone point me in the right direction? What should I study, any references and things like that... Specially the following:
1.- How to implement the imagery (like, can i take it from google maps or something)
2.- Is there a standard database to connect to to determine the device's location, and how to make the device location-aware
3.- How does the coordinate system work
Thanks in advance!!
