结果说明,环境减灾卫星影像基本能满足水稻种植面积提取和产量预报的需求,能够在遥感估产中推广应用。
The results suggest that HJ1A/B images could basically meet the demand of rice growth monitoring and yield forecasting, and could be widely applied to rice production monitoring.
然后在植被信息类内再进行小尺度分割,利用NDVI并融入几何特征进 一步提取冬小麦种植面积及空间分布。
The first step was large-scale segmentation, in which the image was classified as vegetation and non-vegetation by NDVI. The second step was small-scale segmentation;
