In the Takeuchi laboratory, remote sensing technology has been using for the application areas such like atmospheric environment, high carbon reservoirs and urban environment. For this case, the objects are detected by various sensors and modeling can be done by extracting the useful information from the captured data.
The spatial scale is varying from urban/local to global level. The sensors named according to the wavelength they are used in the electromagnetic spectrum such as hyper-spectrum, visible, near infrared, thermal infrared and microwave and use relevant data based on the purpose of the application and objects.

Atmosphere / High carbon reservoirs

In recent years, increase of green house gas emission and air pollution became a serious problem in the world. In this case, anthropogenic impact is significant in the context of urbanization, forest fire for cultivation and land reclamation on coastal ecosystem and wetlands. Understanding the reciprocal relationship among the CO2 source and pools and the terrestrial ecosystem and atmospheric environment is necessary to solve the problem.
In our laboratory, we extract ecological parameters from satellite data and estimate terrestrial/coastal CO2 and CH4 for wetlands.

Since the world's population increase, rice cultivation in South East Asia is an important industry as a food source. In this region, though the rice production mainly depends on the annual precipitation, the trend of decreasing is occurred due to the drought. In our laboratory we aim to estimate the rice harvest and develop cropping calendar using remote sensing technology.

Urban environmental assessment

It is important to understand environmental problems specific to urban area because of the urbanization have progressed in the world. With aid of satellite data we could estimate the temperature and humidity and analyze the characteristic of atmospheric condition in mega cities.

Natural disaster

Due to the global warming combined with excessive human activities, various natural disasters happened all over the world. It was not only a threat to human life, but also related losses in infrastructure and economy.
In our laboratory, with use of modern computing power, we develop a new framework to detect the natural disaster、carry out disaster forecasting and evaluation by integrating real-time computing, remote sensing and GIS.

Field survey

In situ measurements are important to carry out accuracy assessment for the retrieval data from satellite images. In this case developed GPS photo database software can be used to understanding the land use land cover types where the measurements have been took place. Moreover we aim to estimate the grassland biomassrice by combining satellite and in-situ measurement data.
