Study On Forest Resources Inventory System Based GPS Post Processing Differentiation

Forest resources inventory is a basic work of forest construction,and is an important component of forest resources monitoring system .Recently,as GPS is developing,GPS is widely used in forest resources inventory.however,precision of gps isn't high,so how improving the precision of forest resources inventory becomes a main problem solved.GPS post processing differentiation is a typic method of improving precision,the thesis hope that applying GPS post processing differentiation in forest resources inventory improves the precision of forest resources inventory.By analysing the status of forest resources inventory and the theory and arithmetic of GPS post processing differentiation, The thesis puts forward the flowchart of forest resources inventory based on GPS post processing differentiation.By this,the thesis designs the general frame of the system that including GPS data collection system and GPS post processing system,and design frame and function of each system.Last the thesis validates the system using GPS and GPS post processing program,the result indicate that the precision of GPS post processing differentiation in forests is less than one meter,and the way can improve the precision of forest resources inventory.Applying GPS post processing differentiation in forest resources inventory improves the precision of forest resources inventory,make the country know the forests'distributing and number accurately,provide the guarantee for the forest department.
