Abstract: After years of extensive testing and practical applications of forest change detection of satellite image,we present in this paper anengineering procedure and method system for forest change detection based on object-oriented analysis of high-resolution remote sensing images,which included image preprocessing,sub-compartment thematic map preparation,image segmentation and information extraction,object-oriented classification,classification output modification,change objects extraction and field work map production.The methods had no complex image calculation,were easy to learn,could easily streamline the operation,and non professional person could complete one operation after the short-term training.Dealing with one time image and thematic map and time images,the paper introduced the application of this procedure and method system.
