Abstract:

On the basis of testing research, the technology course is put forward, which is pre-processing of remote sensing data, sample plot surveying, the congruence of prophase surveying information, image distinguish, the estimation of surveying factors supported by GIS. A technology method for remote sensing distinguish and the estimation of sub-compartment surveying factor by taking full advantage of prophase surveying information and attribute information of sub-compartment can effectively improve the ratio of distinguish and the estimation precision of surveying factors. Meanwhile, the basic map of 1∶10 000 has been produced, the practicability of surveying result has been increased.
