The Research Center for Digital Mountain and Remote Sensing Application at the Institute of Mountain Hazards and Environment (IMHE), Chinese Academy of Sciences (CAS), is a research unit specially focusing on developing key geospatial techniques based on geographic information systems and remote sensing methods. The purpose of this research is to dynamically monitor, evaluate, and assess the mountain ecoenvironment, especially in the mountain areas of southwest China, but also extending to the whole of South Asia. By applying multisource remote sensing observations at different spatial scales (point, local, regional, and continental) and using different data sources (in-situ measured, air-based, and space-based), the Center aims to develop key quantitative remote sensing methods for mountain areas and to construct an integrated platform for mountain geoinformation sharing and application. Based on these tools and activities, it seeks to provide scientific evidence and technical support for related research in the fields of mountain eco-environment, mountain geohazards, and mountain development in China.
