Study On Application Of Unmanned Remote Sensing Vehicle (URSV) In Forest Survey

As an important basic work of forest on new century; the technologies of forest survey have been developed sufficiency in recent years. Application of "3S" and relevant equipments improved the quality of forest survey efficiency; we have got a lot of theory and experience. But, method mainly based on satellite RS date will unable to meet the need of high-dynamic,high-precision and lower price of government users. Satellite remote sensing technology also has any defect. Based on plenty of experiment, by using "Supported Aerial Triangulation" method, this paper contrasting and analyzing the different between orthophotomap and measurement data, try to test the URSV's performance on forest survey in different terrain. Finally, this paper forecast the technological positioning of URSV.As a result of experiment, URSV will be an effectual tool to replace ground survey, application of URSV will be cheaper and efficiency. Experiment date proved, URSV can get high-precision orthophotomap on condition of even terrain without any ground control points, it can also orientate the forest land by using topographic map.Refer to the application situation of URSV all over the world; this paper estimated the application feasibility of the URSV on the National Forest Resources Inventory, the second type inventory and forecast of forest pests, and so on. Corroding to this, we have mapped out the next research goal.
