| 摘 要： | 时相和光谱特征信息在农作物种植分类提取方面具有十分重要的应用价值。以黑龙江大型农场--友谊农场为研究区域,利用4景不同时相的TM和SPOT卫星遥感影像,提取相应时相的NDVI时间谱图像数据作为新波段信息,在分析地物目标在相应影像各波段上光谱和时间特征的基础上,设计了决策树分类算法,通过对待分类影像进行系列阈值分割和掩膜处理,成功提取黑龙江友谊农场的大豆、玉米和水稻的种植信息,分类总体精度达到98.67%。

| Abstract: | Spectral and temporal information can improve crops classification precision greatly.In this paper,4 multi-temporal TM & SPOT images were selected on Youyi farm in Heilongjiang province.We used the NDVI as a new band information by extracting the NDVI information on the correspond time.By analyzing the spectral and time feature of the objects on each band,we designed a decision tree classified arithmetic.Finally,after series value division and mask management,the areas and distributions of dadou,yumi and shuidao were successfully remotely sensed with an overall accuracy of 98.67% . |
