Chennai is a city with high population density extending its suburban limits day by day. Having an international importance in industrial and tourism sector the city is flooded with naïve commuters. The public does not know the nearby location and the level of services provided by the hospitals. The lacuna of such information at hand may cause several causalities. This insists for the need of Location Based Services (LBS).
The LBS refers to the applications, which react to a geographical trigger. A geographical trigger can be in the form of a signal generated by a GPS device or by any pointing device on the satellite image of the city. On the basis of the geographical position given as the input, the application will have the capability to integrate these spatial attributes with the non-spatial database. The result shown will be all the corresponding medical services surrounding the GPS location specified as the input.
The user will have a choice of giving a query in the form of specialization of hospital, or the nature of illness, which the patient is looking for. Based on the input, only those hospitals and clinics will be displayed which will provide service of the user queries.
Other than the database of the medical services, the application will also provide the shortest and the quickest route from the current position to the required hospital or clinic. So that a visitor to the city will have his ease in locating the nearest hospital in due time. This can save a lot of time which otherwise can turn to be fatal.
The project makes use of the dot Net technology for the application development with the help of ASP MAP 3.0, a third party component. The spatial database is maintained in the Shape file format while MS ACCESS is used to store the non-spatial database. ArcView 9.1 is used to generate the Shape files, which can be superimposed on the satellite image to get a real time view of the Chennai city. The vector file will be associated with the database tables. All the hospitals are tied up with its geographical coordinates, which are useful in mapping it on the vector map.
The interface will show the Chennai city map with the areas demarcated. The user can pin point his location exactly on the map. The application will show all the hospitals serving in a particular department in that area and also gives a choice to the user to view the database of all the doctors present on duty and the emergency contact numbers
