For the first time in Vietnam, scientists from the Department of National Remote Sensing (NRS) have researched and applied remote sensing and GIS technologies in monitoring the coastal corridor.
This is an important scientific research that contributes to providing the scientific and practical basis for the application of remote sensing technology and GIS in the establishment, management, protection and rational use of the coastal corridor. At the same time, the scientists propose a model to monitor the coastal protection corridor by GIS technology.
As a rule, in order to establish a coastal protection corridor, a huge amount of information and data related to the coastal area needs collecting and developing, such as: oceanography, natural conditions of the coast, socio-economic, coastal ecology, economic development planning, etc. However, information and data related to coastal areas in localities are still limited such as lack of synchronization, not regularly updated and insufficient. This makes it difficult to establish a coastal protection corridor.
With the technical attributes of continuous imaging in orbit, GIS technology allows to monitor changes in the status of coastal protection corridor over time and provides information for managers to help support timely decision-making in the management, protection and effective use of coastal corridor.

The research team of Department of NRS has implemented the project: “Application of remote sensing technology and GIS in management, protection and rational use of the northern coastal corridor, piloted in Nam Dinh province “.
This study has contributed to building a scientific and practical basis as well as evaluating the applicability of remote sensing technology for the establishment of a coastal protection corridor as well as sustainable exploitation of the coastal protection corridor for the purpose of economic development, improving living conditions of coastal people more prosperously.
By using remote sensing technology with continuous satellite photography, it is possible to monitor changes in riverbanks and coasts in coastal provinces from the past to the present, and assess trends of fluctuation in the future to promptly provide solutions to prevent shoreline erosion.
For exogenous causes, remote sensing can provide most of the information about the wave field such as wave direction, wave height, flow direction, flow rate, and suspended matter content in the sea surface.
Highly appreciating the results of the Project, the Department of NRS recommends that it is necessary to strengthen the application
