森林火灾遥感监测方法适用性研究
Study on applicability of forest fire detecting algorithms by Remote Sensing
摘要
Abstract
This paper explored the applicability of three commonly used satellite fire detecting algorithms (threshold-based, contextual and fuel mask), to different regions, climates and remote sensors by using nearly synchronous MODIS and HJ dataset of two different forest fire incidents. The results show that, threshold-based algorithm is more efficient but lack of applicability, while contextual algorithm is flexible and stable to external environment. Both threshold-based and contextual algorithm couldn't remove false fire detections caused by nonvegetated area. As an effective supplementary mean, fuel mask algorithm could efficiently find false alarms due to bared land and human productive activities. For the regular operation of forest fire detecting, contextual algorithm is recommended due to its better applicability.关键词
