IJSTE - International Journal of Science Technology & Engineering | Volume 1 | Issue 11 | May 2015 ISSN (online): 2349-784X All rights reserved by www.ijste.org 29 Location Tracking using Google Geolocation API Monika Sharma Sudha Morwal Department of Computer Science Department of Computer Science Banasthali University Jaipur, India Banasthali University Jaipur, India Abstract In this paper we present a fully implemented system which is used for tracking the location. The location of the user will be tracked with the help of Google API. Location tracking will be helpful for various applications. By using this system we obtain the current geographical position of the hosting device or the user. Keywords: Location Tracking, API, GSM, GPS ________________________________________________________________________________________________________ I. INTRODUCTION Location Tracking is becoming very much popular in these days. Any location or the place can be identified in terms of the geographical coordinates. The geographical coordinates of the places are latitude and longitude .The location of the user will be tracked via any of the technique either by implementing GPS device or by using one of the services of Google i.e. Google maps API, Google Geolocation API, Google places API. The current location of the user is tracked with th e help of the Google’s GPS service i.e. Google Geolocation API. II. RELATED WORK OF COVERAGE 1) Prawat Chaiprapa, Supaporn Kiattisin and Adisorn Leelasantitham[1] presents a real-time vehicle tracking system using a global positioning system (GPS) module to retrieve the present location of the vehicle, and forward it to microcontroller and to connect internet by a general packet radio service (GPRS) for displaying a real time on the website map developed by Google Map which allows inspection of vehicles at all times. With Google maps Vehicles can be monitored and located effectively. 2) Shaveta Bhatia, Saba Hila[2] presents a “Localize Intelligence Algorithm” in the field of Location tracking .In this algoritham the location of the person is tracked with the help of mobile phone. For example, if a mobile user is at his own home or his friends home, then the application tells us his approximate location. For example the sector no. 3) Tekawade, A. Tutake, R. Shinde , P. Dhole,S. Hirve[3] presents a mobile tracking application for locating the friends using location based services. They use the GPS as location provider through geographic location for mobile network. This application enables the users to check the the exact location of mobile user by using Google map. 4) Mahesh Kadibagil, Dr. H S Guruprasad[4] develop a system which includes a mobile client, a repository, a web client and a map service. The mobile client is used to find location and send a Popup SMS to user when his/her friends or family members come around the user’s area of direction. This location information can be sent to the server and the same information can be managed and viewed using the web client by other users. 5) Anil Birajdar, Manisha Koul,Mridushi Srivastav, Pooja Nair [5] in their research they develop a simple and cost- effective system which helps the users in tracking the colleagues and friends with in a campus. This system makes use of the IMEI information and Wi-Fi access points within the campus to obtain the current location. 6) Varun Pande, Wafa Elmannai, Khaled Elleithy[7] present present a paper in which they make use of the Google Latitude to define the location of a specific Wi-Fi tower which enables the users to locate the location of the mobile phones. They use the coordinate’s values for geolocation of the current location. III. VARIOUS TECHNIQUES USED FOR TRACKING Location tracking has been used in many of the organizations .There are different ways in which we track the location of the user. These are given below. Global Positioning System GPS: A. The GPS is a space-based satellite navigation system which provides location and time information in all weather conditions, anywhere on or near the earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides
