We have started developing an application for location aware emergency service. The users can connect through computer,smart phone or even through WAP.
The problem we are facing is, we don t know how to get the location of the user who is asking for service. If it is GPS enabled smart phone, it can be located though the app. I have seen google map locating the cell phone using BTS tower s location in GPS-less smart phones (Like Nokia E-series). But I couldn t find any API in Nokia site which I can use to get that location or BTS tower based locating service.
And the main problem remains for the computer. It is enough if I can locate the city for computers. I have seen in several sites (like ip2location.com) locating the IP address up to the city level (sometimes more). Isn t there any other way to locate IP address for free of charge?
If I summarize my questions-
- How to get BTS tower based location service for cell phones?
- How to locate user s IP address upto at least city level ?
- How to convert the latitude-longitude into address (at least up to city level)? free of charge?
- How to convert the address into latitude-longitude? free of charge?
Thanks in advance.
