Monitoring forest biodiversity is essential to the conservation and management of forest resource. A new method called “spectranomics” that map forest species richness based on leaf biochemical and spectroscopic traits using imaging spectroscopy has been developed. In this study, we use this method combined with the airborne imaging spectroscopy (PHI-3 with 1m spatial resolution) data to detect the...
Opium is a narcotic obtained from opium poppy and is the raw material of heroin for the illegal drug trade. Monitoring the illegal concentrated cultivation of opium poppy in major regions is critical for the understanding by governments and international communities of the scale of illegal drug trade. This paper investigates whether opium poppy can be discriminated from its coexisting plants using...
This paper describes the characteristics of vegetation condition index (VCI), temperature condition index (TCI), normalized differential water index (NDWI) and vegetation health index (VHI), and uses the relationship between above indices and relative soil moisture to evaluate the index adaptation. The analysis means that different indices have different adaptation. NDWI is not sensitive to the drought...
