Abstract

At present the mostly used land alteration survey method of direct field surveying investigation has the shortcoming of the separation of internal and external operations. This paper puts forward an internal and external integration of land alteration survey modes of PDA + GPS + ArcPAD. On the basis of demand analysis and logical structure design, the paper puts forward a land alteration data structure for the storage of PDA, studies a development method for system implementation, and further explores the solution to the problem of coordinate conversion in the GPS collection. This study is helpful for the changing of the current alteration survey mode, improving work efficiency, and reducing the error caused by the separation of internal and external operations, etc.
