摘要
干旱是影响河北省农业发展的主要气象灾害之一,从遥感监测干旱图像产品的自动化生成软件设计的角度,以植被供水指数法监测干旱为例,从实际应用出发,介绍了其中2个主要环节:信息系数自动获取和假彩色图像自动生成的设计思路、物理意义及算法实现。
Drought is one of the main meteorological disasters that influences agricultural development of Hebei province. From the viewpoint of automatic making software design of drought detection image with telemeter, taking water-supplying for vegetation as example, two main taches: automatic acquisition of information coefficient and automatic making of false color image, were introduced, and the design workflow, physical meaning and arithmetic realization were explained.
