- W2348923675 abstract "ZY-3 is the first high resolution satellite of our country, which was launched in 2012, was used in stereo-survey and drawing including forest and vegetation and was one self-developed and for civilian. Based on the fine-processing of the ZY-3 data of Lijiang River Basin, the spectral features and texture features of typical ground objects in the area were analyzed, ZY-3 decision tree models were established that were suitable for vegetation information extraction, and then the land type if the studied area were divided into 9 kinds, they are needle-leaved forest, broad-leaved forest, shrub, bamboo, farm, buildings, naked land, water and others, finally the vegetation information of all kinds were extracted and the extraction accuracy were tested. The results show that :(1) ZY-3 is very suitable for vegetation extraction, better for the information extraction of needle-leaved and broad-leaved forest than others;(2) All the land types' information extraction from the data are good, the total classification accuracy was up to 91.96%, and the Kappa coefficient was 0.9029. It is feasible that the studied area vegetation information is extracted according to the spectral features and texture features of the studied area data, by using decision tree algorithm models and choosing an appropriate threshold value." @default.
