Summary

Google is enhancing its indoor positioning capabilities, addressing the limitations of existing services like imprecise floor detection and poor GPS performance within covered structures. A new Android application, compatible with version 2.3 and later, collects nearby WiFi and GPRS signals to accurately determine a user's indoor floor position. This initiative involves collaboration with venue owners, who will update their floor plans to integrate with Google's map service. While promising a significant improvement in indoor navigation accuracy, the application is currently available exclusively for commercial tenants.

Google Maps, Bing Maps, and some map providers have offered indoor map service such as in  the airport, major shopping malls and stadiums for some time. The problem is that these indoor maps can not precisely tell you which floor you are on a map, the GPS obviously can not work very well in this environment, WiFi and GPRS positioning is not very precise. Google announced the improvement program of Google Maps for accurate indoor positioning. The current owners of these places will cooperate with Google, they will update the floor plan for Google's map service, users can access their current position through the latest Android application .

The application is running on Version 2.3 or later, after installation, it can collect WiFi and GPRS signal nearby you and resolve these data to tell you the indoor floor position, However this application currently is only released for commercial tenants.

Indoor Positioning shall be defined as any system that attempts to provide an accurate position inside of a covered structure, such as an Airport, a Subway, or a Mall.

The key is the right programmer. You shulod be able to explain what you want done in your own language, and he or she shulod be able to translate that into a design specification. It's not your job to design the program, but rather to simply describe what you want. It's up to the programmer to understand what you want and implement it to your specifications.If you can point to other programs or Web sites that are similar to what you're looking for, that would help. If you can sketch a picture of what you want it to look like, that would also help though in the end you may want some kind of professional designer to do that part so it looks good (that is, it may not look the way you first thought it shulod look it shulod end up looking better).If there are computations or information look-up involved, you shulod describe where the data comes from and what the formulas or processes are to turn the data into the results you want. One of the key features of your specification shulod be your desire that others in your industry use your solution. It is easy to design an application that works for your company but cannot be easily re-targetted to work for another company. The ability to have the application be used by multiple companies needs to be designed in from the beginning. It will make the initial implementation more expensive but shulod make subsequent implementations trivial.
