Inter-Sensor Comparison between THEOS and Landsat 5 TM Data in a Study of Two Crops Related to Biofuel in Thailand

Knowledge of the spatial distribution of biofuel crops is an important criterion to determine the sustainability of biofuel energy production. Remotely sensed image analysis is a proven and effective tool for describing the spatial distribution of crops using vegetation characteristics. Increases in the number of options and availability of satellite sensors have expanded the horizon of choices of imagery sources for appropriate image acquisitions. The Thailand Earth Observation System (THEOS) satellite is one of the newest satellite sensors. The growing number of satellite sensors warrants their comparative evaluation and the standardization of data obtained from various sensors. This study conducted an inter-sensor comparison of the visible/near-infrared surface reflectance and Normalized Difference Vegetation Index (NDVI) data collected from the Landsat 5 Thematic Mapper (TM) and THEOS. The surface reflectance and the derived NDVI of the sensors were randomly obtained for two biofuel crops, namely, cassava and sugarcane. These crops had low values of visible surface reflectance, which were not significantly (p < 0.05) different. In contrast, the crops had high values of near-infrared surface reflectance that differed significantly (p > 0.05) between the crops. Strong linear relationships between the remote sensing products for the examined sensors were obtained for both cassava and sugarcane. The regression models that were developed can be used to compute the NDVI for THEOS using those determined from Landsat 5 TM and vice versa for the given biofuel crops

SETTING AN INNOVATIVE MASTER DEGREE ON ENERGY SUPPLY FOCUSING ON ISOLATED AREAS – THE MESfIA ERASMUS+ PROJECT

International audienceMastering Energy Supply focusing on Isolated Areas (MESfIA) Erasmus+ Capacity Building project, aims to provide high quality postgraduate education on energy supply systems for engineers and graduates from science departments, aiming to have activity or to be employed in projects in countries with many isolated areas and insular systems. It is a transnational cooperation activity between Europe and SouthEast Asian Countries (namely in our case Thailand, Vietnam and Indonesia) to improve capacity of Postgraduate Students in S.E. Asian Universities. Energy efficiency is among the items to be addressed in this training
