How to manage forest resources and environment effectively? Remote sensing is a solution of invaluable support for this goal. The purpose and expectation of traditional forest inventory is to provide forest resource with reliable information. However, these inventories usually lack fine spatial resolution and even performed terrestrially only. In recent decades, the great progress in remote sensing and GIS has provided considerable opportunities for such forest inventories. Integrating these techniques and terrestrial data as an analysis of multi-source information is therefore of particular...
