陕西省土地覆盖分类的遥感应用研究

利用监督分类和阚值判别相结合的方法，在对不同地物的地表光谱特征进行分析的基础上，对NOAA和FY－1C卫星各个季相的晴空资料分别进行了计算NDVI与判别分类，制作了陕西省遥感土地覆盖分类图，从而探索了一种通过极轨遥感资料进行宏观的土地覆盖分类的方法，此外，提出的用于遥感图像精校正的火点定位法，解决了地面控制点与遥感图像元的对应问题。

Research on Application of Remote Sensing for Vegetable Coverage Classification in Shaanxi Province

Research on classification of NOAA and FY-1 satellite images, calculatien of NDVI was carried out and the vegetable coverage thematic map for Shaanxi province,was drafted by using the method of supervised classification combined threshold judgment, and based on analyzing spectral features of different surface objects. Then,a method used for vegetable coverage classification was found. And furthermore,the fire-spot-locating method was used to improve the precision of the RS image geometric correction, and so the problems about correspondence between GCP(ground control point) and image point can be solved.
