A method of location technique without network


Location-based services (LBS) are a general class of computer program-level services that use location data to control features. As such LBS is an information service and has a number of uses in social networking today as an entertainment service, which is accessible with mobile devices through the mobile network and which uses information on the geographical position of the mobile device .

But if we have a mobile without network, how can we get the location data? This solution will resolve this problem.

For example:

When I have a travel in a foreign country, we don't know where am I. And the mobile network doesn't work, we can't use the GPS or other location system.

so we want to use a location system which can work well without network.

Core idea:

1)We have a offline map in the mobile, but the mobile can't access the network. How can we locate the position? We can take some pictures from surrounding environment. For example, the guide board, the shop sign on the restaurant or retail store.

2)Then the system can get the keyword from these pictures and search the keywords in the offline map, get the position through the search results of multiple keywords.



1)Location system can locate the position without network and GPS.

2)Location system can locate the position based on the environment pictures taken by user.
