Abstract: With the development of remote sensing science and technology, to carry out the investigation and monitoring of forestry resources has become a principal mean to understand current situation and trend of development with the help of remote sensing images. An IDL-based forestry remote sensing image classification and visualization system, through numerical simulation and calculation results visualization of IMG remote sensing files, has been designed and implemented, combined with a typical problem of remote sensing image detect instances in forestry. The results show that it is IDL(Interactive Data Language) matrix-oriented features and powerful data visualization capabilities that is an ideal tool of detection of forest resources and forestry remote sensing image visualization.
