Abstract Precision irrigation management requires operational monitoring of crop water status. However, there is still some controversy on how to account for stress. To address this question, several physiological, physiological metrics have been proposed, such as the leaf/stem potentials, stomatal conductance, or sap flow. On other hand, thermal remote sensing has shown be a promising tool eff...

Characteristics of reflection spectrum, multi-spectral images and temperature of lettuce canopy were gained to judge the lettuce’s water stress condition which could lead to a precise, rapid & stable test of lettuce moisture and enlarged the models’ universality. By the extraction of lettuce’s multisensor characteristics in 4 different levels, quantitative analysis model of spectrum including 4...

Fuel load and fuel moisture content are crucial parameters in estimating bushfire risk. However, current measures of these parameters are not spatially distributed within fire districts; the district-level indices are derived from pointbased estimates at sparsely located stations. In addition, they are based on meteorological inputs alone, rather than observations, and are the major sources of ...
