高分辨率遥感影像的出现,给林业遥感带来前所未有的机遇,但是高分辨率遥感影像在林业领域中的应用面临诸多问题,如数据源的价格偏高、图像阴影无法去除、树种识别困难和森林蓄积量估测精度不高等,提出了建立主要树种的波谱数据库,采用基于多特征的面向对象的分类技术,提高高分辨率影像在林业中的应用水平等建议。
The high-resolution remote sensing image facilitates the remote sensing of forestry. However,there appear many problems in its application in forestry, such as the high price of data, the irre movability of image shadow, the low accuracy of quantitative estimation, etc. To establish the spectrum database of dominating trees and to adopt multi-feature-based object-oriented classification technology can help to solve the problems.
