Key Words: '''''Mobile GIS, GPS, WAP (Wireless Application Protocol)''''' Abstract: Nowadays the term “mobile” is becoming more and more popular in our daily lives. As a result, “mobile GIS” applications have been developed and applied into various fields, such as GPS car management. So, what is mobile GIS? And what is the future of mobile GIS? This paper presents the concept of mobile GIS, Mobile GIS benefits, mobile customer needs, and some practical applications of mobile GIS in the industry. 1. Introduction With the development of computer software and hardware, as well as the application of WAP successfully in wireless network, and the emergence of intelligent terminals, such as PDA and wireless phone etc,. People owing these intelligent terminals can do their work on the spot at any time or anywhere, which they have to do in their office or home before. Just like, Larry Smarr discusses that “The Internet is the infrastructure that will define the 21st century. In the future, 80% of Internet access will be wireless from mobile devices. ” (Ainsworth, 2002, P.A) In the meantime, apparatus such as GPS, GSM model made for the intelligent terminals have extended the application region of it. The integrated system of the intelligent terminals with GIS, GPS and wireless network become a new application technology. In the GIS field, the integrated system was called mobile GIS. 2. Definition of mobile GIS Traditional GIS mainly focuses on static spacious entity. Therefore it is named “Static GIS”. Static GIS does not involve, and can not depict the characteristics of the nature of the moving/changing world. For example, it can hardly keep track of the real-time changes of the objects under study, such as changes of the boundary of a field, or the owner of the field. Today, we hear more and more about “mobile GIS”. Then what is mobile GIS? What areas can mobile GIS be applied to? Mobile GIS is a special kind of GIS - it focuses on non-geographic moving objects in geographic space, or on the relationship between moving objects and geographic entities. For example, we can integrate GIS, GPS, and wireless internet to build a mobile GIS to monitor vehicle movement. We study the moving vehicle, a non-geographic entity, in geographic entity space. |
