Abstract Field survey is a very important step in the process
of land consolidation and rehabilitation. Traditional methods of field
survey take much time and effort and it is difficult to locate
facilities of projects, to measure area or length and to spot and
record problems quickly and accurately. A global positioning system
(GPS)-based field survey system is introduced. Firstly, the framework
of the system is described. Secondly, the key technologies are shown,
including data preparation, locating accurately, coordinate
transformation, field measuring and field editing. Finally, further
applications are discussed. The major result of this study is a
GPS-based field survey system which will promote the application of
GPS-personal digital assistant (PDA) technology in the field of land
consolidation and rehabilitation, creating an effective method for
improving field survey. In this paper, the authors analyse the demands
of field survey and introduce the basic ideas of system design and the
major functions of the system. This paper also focuses on the
implementation of key technologies which are expressed by unified
modelling language (UML) figures and tables, such as data preparation,
field positioning, coordinate registration, field measurement and
recording. It has been shown that the GPS-based field survey system can
greatly enhance the quality and efficiency of field survey, help solve
many technical problems and make field survey more straightforward.
Widespread adoption of GPS-PDA technology is important to improving
land and resource management.
