We conduct a climate change basic monitoring at terrestrial, freshwater and estuary ecosystem to identify threat factor such as a biodiversity decrease and endangered species increase of ecosystem under climate change.

We conduct a pollination timing impact of pollination insect to provide scientific evidence for management and preservation of a pollination function under climate change.

To provide an adaptation measure based on the risk assessment, we conduct a climate change risk assessment and impact prediction by an ecosystem type.

Water Resources

TOP

Recently, water related disasters such as drought and flood have been increasing rapidly due to climate change, and technologies that can respond pre-emptively and scientifically through the fusion of advanced technologies are being continuously developed.

Recently, the frequency of large-scale water related disasters has increased due to global warming and abnormal climate, and although the scale of the damage is becoming increasingly larger and wider, there is insufficient infrastructure to respond quickly to a wide range of disasters.

In this way, there are increasingly more cases in which the damages cannot be accurately detected and predicted due to frequent floods and droughts in local cities. Therefore, scientific and efficient disaster response and system construction are emerging as urgent and top priority national tasks.

As part of the 'Water Management Research Project' of the Ministry of Environment in 2014, the government will systematically collect and analyze water-related disaster information on the Korean Peninsula and other parts of the world, and to develop technologies that can provide relevant information to government departments and the private sector. We are promoting the 'Technology Disaster Information Platform Convergence Technology Research' project.

Especially, a global water hub will be constructed through a platform to produce and provide information related to water resources and water disasters in the Asian region that includes the Korean peninsula. In this way, it is expected that the technology development that can analyze and predict real-time information related to weather in advance to handles diverse water disasters such as drought, flood and dry stream phenomenon, which are directly connected with peoples’ lives, is expected to be completed.

Planning Support System for Urban and Territorial Planning

TOP

The cities and land use created on the earth have a great impact on the sustainability of the planet. Residential, commercial, industrial and recreational activities, and roads, airports, harbors, bridges, etc., which are the basis for them, require destruction or transformation of existing ecosystems.

In order to develop the city and the land use with minimal impact on the global ecosystem, we must comprehensively analyze big data from global level satellite image data to urban and individual units. It allows to see relationship between cities and land use. By analyzing data from across the globe, you can see how cities and territories are expanding and how they affect the planet.

The KOPSS (KOrea Planning Support System) is a decision support system that provides the information needed for city and land use planning. Five models are developed: a regional planning support model that can diagnose the balanced development status of the land, a land use planning support model that finds the best land for various conditions such as accessibility and land price, an urban renewal support model to find an aged region that needs to be regenerated, and a landscape planning support model that analyzes the impact of new developments on the surrounding landscape in three dimensions, a public facility planning support model to find areas where public facilities are lacking, and resort development.

Evaluation of renewable energy resources through satellite remote sensing

TOP

Currently, the whole world is passing through the age of energy conversion. If the existing energy conversion considered new energy source, the present energy conversion is considering sustainability. As a solution to this problem, the spread of renewable energy is accelerating with the smart energy demand management based on IoT.

Renewable energy using natural energy such as the sun and wind power is very volatile in terms of time and space depending on the weather conditions. Therefore, for the renewable energy generation project, priority should be given to accurate resource assessment. The International Renewable Energy Agency (IRENA) collects various resource maps that can be used for the evaluation of renewable energy resources to support the supply of renewable energy in developing countries and services them free of charge. The Korea Institute of Energy Research (KERI) has advanced the resource evaluation based on existing ground observation, and has produced a new renewable energy resource map on the Korean peninsula using satellite remote sensing data such as Chollian and Arirang, and provides it free of charge through the map book and web service.

Remote sensing for geological survey and mineral exploration

TOP

The KIGAM (Korea Institute of Geoscience and Mineral Resources) is conducting a surface geological survey in the Tsogttsetsii copper mineralization zone of Omnogobi Province, southern Mongolia, with the MRPAM (Mineral Resources and Petroleum Authority of Mongolia) since 2017. In 2018, the distribution of altered and sulphate minerals related to copper mineralization on the surface was mapped using LANDSAT ETM+, ASTER, WorldView-3 satellite data, and drone-based images. The results of the remote sensing analysis were verified by geological field survey and acquisition of hyperspectral data of minerals in the potential area confirmed from satellite analysis.

Also, KIGAM has been conducting geological investigation and exploration activities in Zambia, Tanzania and Mozambique as part of the African Minerals Geoscience Initiative (AMGI) project with the African Union and the World Bank since 2016. In the 2018 survey, Sentinel-1 (SAR), Sentinel-2 (multispectral), Landsat 8 (multispectral) images and DEM data were analyzed for the identification of geologic structures such as faults and for the distribution mapping of surface altered minerals in Tanzania. The geologic remote sensing technology was used for the planning of geological field survey, aeronautical geophysical survey and for the upgrade of existing geological information.

Monitoring ocean environment using ocean satellites

TOP

Development of ocean satellite sensors starts from Ocean Scanning Multi-spectral Imager (OSMI), the optical sensor onboard in KOMPSAT-1 (launched in Dec. 1999). In 2010, the world’s first ocean color sensor on the geostationary orbit, Geostationary Ocean Color Imager (GOCI) was launched successfully, and the data has been used for various scientific and operational applications. Research on the calibration/validation and applications was mainly conducted under the initiatives of Korea Ocean Satellite Center (KOSC) in Korea Institute of Ocean Science and Technology (KIOST), contributing to various maritime issues in Korea such as red tide, floating algae, sea fog detection, fine dust quantification, etc. GOCI data is also being distributed to public via the KOSC homepage as well as through the Naver thematic map service (Korea’s leading portal service).

The GOCI processing techniques and product algorithms have been developed through the research projects titled “Application research on the geostationary ocean color satellite (first and second phase)” for more than 10 years, where various international research activities were performed (Korea-US joint field campaign between KIOST and NASA, 2016, installation of 2 AERONET-OC, member institute in international ocean color coordinating group (IOCCG), and hosting International Ocean Color Science Meeting (IOCS-2019), etc.

The Korea Ministry of Oceans and Fisheries plan to launch the second GOCI (GOCI-II) in late 2019, and promoting other polar-orbiting satellites for ocean monitoring through the government’s earth observing program named “next generation middle-size satellites”.
