Mobile GIS Mobile GIS là giúp đỡ người lao động lĩnh vực bằng cách cung cấp cho họ với bản đồ GIS trên các thiết bị tính toán cầm tay của họ. Lĩnh vực công nhân được trang bị với GIS điện thoại di động có thể cập nhật cơ sở dữ liệu GIS doanh nghiệp của họ từ các lĩnh vực. Mobile GIS mang lại bản đồ GIS cho người lao động lĩnh vực sử dụng máy tính di động và PDA. | CHAPTER 7 Mobile GIS Mobile GIS is helping the field workers by providing them with GIS maps on their hand-held computing devices. Field workers equipped with mobile GIS can update their enterprise GIS database from the field. Mobile GIS brings GIS maps to field workers using mobile computers and PDAs. Copyright 2005 by Taylor Francis LEARNING OBJECTIVE The learning objective of this chapter is to determine the applications of mobile GIS technology in water industry. MAJOR TOPICS Mobile GIS basics Mobile GIS applications Wireless Internet technology GPS integration LIST OF CHAPTER ACRONYMS LBS Location Based Services PDA Personal Digital Assistant RTK Real Time Kinematic MOBILE GIS BASICS Integration of GIS with consumer electronics such as cell phones and automobile navigation systems has spawned a whole new industry called location-based services LBS . LBS services are used for managing dispatch and routing fleets work orders and field crews all of which improve customer service. Telegeoinformatics is also a new discipline resulting from the integration of mobile computing with wired and wireless communications GIS GPS and remote sensing technologies Karimi and Hammad 2004 . GIS lies at the heart of most mobile information resource systems. For example it is now possible to wirelessly transmit a GPS location from the field which can then be viewed on a GIS map via the Internet. Using GIS directly in the field for data collection into a GIS database is referred to as mobile or field GIS. According to a recent study about 40 of all mobile data applications in utilities are using a GIS Wilson 2001 . With mobile GIS feature location and attribute data can be verified augmented and immediately updated. New features can be added existing features moved to their correct location and nonexisting features deleted in the field. The ultimate goal of a mobile GIS is to link mobile workers with data to make their jobs easier and more efficient. Mobile computers are the field
