Abstract
Land resources are essential to human survival. Catching current status of land resources and information of the land change is the basis for constituting an overall plan of land use and deciding on land. In recent years, the global positioning system (GPS) has widely been applied in the land change survey, such as resources management, urban planning, landscape construction, and so on. It has many advantages compared to the traditional survey techniques. Real-Time Kinematic GPS (GPS-RTK) developed from GPS is a more secure and fast way, which has some advantages of shorter observation time, high positioning accuracy, unnecessary intervisible and direct result of exact coordinate in field. This paper uses GPS-RTK technology in the land change survey. Through analyzing the processing and error sources of the method, the paper tries to demonstrate the feasibility and practicality of the method.
