摘要
探讨了运用软件程序对遥感影像灰度值的一定阈值范围进行自动区划图斑,根据野外踏查路线建立与卫片相对应的解译标志特征库,通过多期森林资源连清数据建立估测模型,结合外业抽样样地回归测定小班蓄积的森林资源调查方法。
The software program is used to automatically map the grey value of remote sensing image according to a certain threshold range. The field mapping is used to establish the signature database corresponding to the satellite image. The estimation model is established by using multiple periods of forest resources to clear the data. Combined with the sampling of plots in the field, the forest resources survey method for small class accumulation was determined.
