Abstract
Flooding and oil spill disaster relief using Sentinel of remote sensing satellite data is conducted. Kyushu, Japan had severe heavy rain from 26 August to 30 August 2019. Optical sensor and Synthetic Aperture Radar: SAR onboard remote sensing satellite is used for disaster relief. NDVI and SWIR data derived from the Sentinel data are used for disaster relief. Merits and demerits of the optical sensor and SAR instrument are compared from the disaster relief of point of view.
Highlights
On the morning of August 26, the front line near the southern part of Kyushu moved northward to the vicinity of the Tsushima Strait on the 27th day
Due to the oil spill, surface vegetation is covered with oil so that the surface reflectance and NDVI are decreased

Summary
On the morning of August 26, the front line near the southern part of Kyushu moved northward to the vicinity of the Tsushima Strait on the 27th day. Due to the heavy rain, landslide and oil spill disaster is occurred Such disaster can be relieved from space, spaceborne mission instrument data. Typical instruments of passive type are optical sensors, visible to near infrared radiometer, shortwave infrared radiometers, thermal infrared radiometers and microwave radiometers while those of active instruments, Synthetic Aperture Radar: SAR. Both types of mission instruments have merits and demerits for disaster relief. Results show effectiveness and efficient usage of SAR and optical sensor data for landslide and oil spill disaster relief. Experimental results are described followed by conclusions together with some discussions
