Urban heat environment has a close relation with quality of life of urban citizens. Land surface temperature (LST) retrieved from remotely sensed thermal infrared imagery can be used for urban heat environment studies. However, the rather low spatial resolution of currently available remote sensing thermal imagery (e.g., Landsat ETM+, its thermal band is in the spectral range of 10.40–12.51 µm and...
Land Surface Temperature (LST) is an important parameter to study the earth's surface thermal environment and the exchange process of matter and energy of earth's various systems, etc. In many studies, thermal infrared (TIR) images with both high spatial and frequent coverage were highly required to obtain LSTs. However, at current stage, there is no such kind of satellite sensor can completely meet...
Forests play an important role in protecting the coastal environment by slowing down the wind speed and fixing the soil. With the aid of Remote Sensing technology, the monitoring and analysis of the wind-preventing and sand-fixing effects of the coastal protection forests can provide useful and near real-time information for better forest construction and management in such areas. One major issue...
Land surface emissivity (LSE) has been an essential parameter for many quantitative thermal infrared remote sensing models. There are three main ways to acquire it: laboratory measurement, field survey and remote sensing retrieval. Due to the inconvenience of in-situ measurements as well as the limited surface coverage of the former two methods, remote sensing retrieval has become the major option...
In present paper, to effectively improve the accuracy of burnt scar mapping in hilly areas, a new method by combing multiple spectral indices with Support Vector Machines (SVM) has been put forward. Firstly, the Landsat TM image was geometrically and atmospherically corrected. Secondly, two widely used thematic-oriented spectral indices, namely, the vegetation index SAVI and the water index MNDWI...
