Aim

Our aim is to develop a system for addressing unavailability of localized, timely

geographical information in smart phones with the use of GPS technology.

12

Objectives

Design and develop a system to address various forms of geo information needs

Generate a quality product achieving the required security

concerns

Obtaining a business value to the final product from the

industry

Enabling the users to feed information to the system

Studying of the technologies that can solve the problem

Evaluation of the proposed solution

Limitations Response time was affected by the free server

we used

Functionalities were implemented as the client

requested. (eg: Concept)

Suggested business model can be implemented

with the approval of the client only
