Method for land resources monitoring by remote sensing data on large-scale

Remote sensing data is widely used in resource surveying, monitor and evaluation. The data processing level is a key factor which controls the use extent of remote sensing technology. Based on the comparison among different method of land use change and land cover type detecting, map selection method of land-use change detecting, land use map update and land cover type abstraction were studied. As a result, practicable method of land use change and land use detection technology were provided for large-scale.
