The temporal features of various land objects were studied based on the MOD13Q1,and built the decision tree model for the land cover classification of Yanhe basin by filtering the MODIS-NDVI time-series data of 2006 in the area via the HNATS(Harmonic Analysis of Time Series) algorithm;analyzing the temporal curve features of NDVI,and selecting the rational quantitative classification features for the decision tree model,building masks for each land cover,and performing the unsupervised classifications in th...
