STUDY ON THE NEEDS AND PROPOSAL FOR HIGH AND VERY HIGH RESOLUTION SATELLITE REMOTE SENSING SYSTEMS IN VIETNAM

The rapid development of remote sensing applications in Vietnam has resulted in high demands on satellite data, especially high and very high resolution images. It is the fact that, the country's existing remote sensing facilities are not adequate to satisfy its user's needs. Consequently, planning for new earth observation satellite systems is of a critical issue. This paper is firstly evaluating the requirements for high and very high resolution satellite images on various applications including land resource management, surveying and mapping, forestry, environment monitoring and agricultures. An assessment on data provision capabilities of existing Vietnamese Earth Observation systems VNREDSat-1 (Vietnam Natural resource, environment and disaster monitoring system) is also performed. Eventually, the authors suggest a newly planned remote sensing system for Vietnam, focusing on a high and very high resolution optical systems.
