Location Based Services(LBS) GPS and GIS

By | March 24, 2013

Location Based Services(LBS)  are offered based on user’s geographical location provided by positioning technology such as Global Positioning System , and with the help of Geographical Information Systems.  In this paper we have approached a technique to use GPS in advertising. Here the authors present an idea that is a commercial advertising feature. For example, any commercial firm will be advertising for publicity, so they will incorporate the advertising feature into devices. In short, a new advertising application is proposed, which is more useful for commercial firms eager to promote their business around their own location. The idea is to allow a  commercial firm willing to advertise, shall provide their location and will mention the area in which they want to advertise. So whenever someone with  enabled device enters the advertised area will automatically be notified with their commercial. The main objective of this application is to use geo processing tool with network analyst. 

An   LBS  allow consumers to receive services based on their geographic information about restaurants, retail stores, and travel arrangements. Such services can be provided in response to a customers manual input of his or her location to track the location of the consumer automatically. 

Geographic  Information System (GIS), also known as a geographical information system or geospatial information system, is a system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to the Earth. LBS and GIS have some particular similarities. Geographic data is an important aspect of any location system. Geographic Information Systems (GIS) provide the tools to provision and administer base map data such as manmade structures (streets, buildings) and terrain (mountains, rivers). GIS is also used to manage point-of-interest data such as location of gas stations, restaurants, nightclubs, etc. Finally, GIS information also includes information about the radio frequency characteristics of the mobile network. This allows the system to determine the serving cell site of the user. GIS uses information from many different sources in many different forms.

The primary requirement for the source data consists of knowing the locations for the variables. Location may be annotated by x, y, and z coordinates of longitude, latitude, and elevation, or by other geocode systems both GIS and LBS have different origins each having special kinds of user groups. GIS is much older and evolved with the application of geographic data obtained from GPS satellites. It requires extensive computing resources but has been offering a wide range of functionality. Whereas LBS were originated recently by the development of mobile devices and it is more popular among individual user rather professional organization. Hence, LBS have its origin in GIS and is an intersection of different technologies including GIS, mobile Internet and telecommunication. So Geographical Information System is an inseparable part of Location Based Service like Global Positioning System (GPS), and Radio Frequency Identification (RFID).

Currently GPS system used for following things.

1) A GPS can help you locate a lost child. There are several GPS devices on the market that are designed to be used for this purpose. Some look like watches that lock on a childs wrist. Others look similar to cell phones. Some are even equipped with panic buttons that allow the user to press a button during times of distress, signaling that he needs help. The signals from these devices are often transmitted to a central location that will then call you on a predetermined phone with the location of your child. Of course, these devices can be used for other people besides children.

2.) A GPS can help you locate a lost pet. A tracking device is placed on your pets collar or in a special backpack that can be fitted to your pet. When your pet goes missing you can retrieve the information about its whereabouts through the type of transmitter that you have chosen. Two popular methods of retrieving the information are through a cell phone and the Internet. There are also software programs available that will alert you if your pet has gone out of boundaries that you have predetermined.

3.) When working in conjunction with your cell phone, a GPS can allow you to call for assistance from anywhere, and your location can be tracked. This means that if you get into a car accident in a location that is difficult to identify, emergency vehicles can easily find where you are. Or, if you are hiking in the woods and become injured, help can track you down.

4.) You can use your GPS as an exercise monitor. If you walk, run or cycle regularly and like to change your route frequently, a GPS is a great tool to use. It can let you know how fast you are moving. It can also tell you how much distance you have covered. You can easily ensure that you get the exact number of miles in that you want, even when you are taking an unfamiliar route.

5.) A GPS device can help you create a high tech scavenger hunt. A GPS scavenger hunt is much like a traditional scavenger hunt. Teams of people have to hunt down clues which lead them to their final destinations, often collecting items along the way. However, the teams use GPS handheld receivers to get from clue to clue as opposed to traditionally written directions.
