review

The main idea of my prototype is to create a Community Location Aware Application. At this way, as it is only a prototype (I know it is not very accurate), I have decided to associate tags (descriptions) and GPS coordinates to GSM location info (cellId + LAC + OC + CC). At this way, the user will be able to use community location features without having GPS coverage (i.e. indoors), if exists in the database a GPS position associated to his GSM info.

It is composed of two applications:

The first one is a Symbian Series60 3rd edition FP1 application (C++) which has implemented the following
functionalities:

-Gets locations information of the GPS, and if not available (i.e. indoor) gets the GSM information
(cellId + LAC + OC + CC). This information is sent over http to a small server to be stored in a database.
-Shows information about location of your friends, your location... (Google Maps)
-It allows to tag the current location of an user, being sent this location to the http server to be stored
in the same database.

The second one is a very small j2ee application, which has two servlets:

-The first is used to receive http POST from Symbian client (location info and tagging), and stores this information
in a MySQL database
-The second is used to create dinamically some small maps using Google Maps API. Every location mark in the map
contents the date, the tag of the user for this place...

There are three types of maps created:

1) Show last location of an user --> Sending to the servlet the IMEI (if is your location from phone) or the username (if a friend) it returns a map which contents the location.
2) Show current location of an user --> Sending GSM information (cellId + LAC + OC + CC) it returns a map with the current location of the user.
3) Today route --> It draws all locations of an user in a day, drawing the directions also.

For all maps it is necessary to have available relation in database between GSM info and GPS info in database.
