Design and implementation of remote sensing information system for dynamic monitoring cyanobacteria bloom in Taihu Lake

对于动态监测太湖蓝藻水华空间分布的业务需求,构建相应遥感动态监测信息系统可以为之提供有力支持。本文从系统总体结构和系统技术流程角度介绍系统的构建思路,并且探讨研发本系统的关键技术。本系统采用系统配置与单体模式技术实现系统架构,并设计良好的数据结构组织影像数据处理过程,同时将当前蓝藻水华遥感信息提取的主要方法应用到系统影像建模中,使得本系统在太湖蓝藻水华遥感监测的业务化运行中取得明显效果。

For dynamic monitoring of cyanobacteria bloom in Taihu Lake, the corresponding dynamic monitoring of remote sensing information system could be built to provide effective support. In this paper, the overall structure and technical processes of the system were introduced. The key techniques were explored. System configuration and singleton mode were adopted to implement system archi- tecture, and well-designed data structure was carried out to organize image data processing. The inversion model methods to obtain cyanobacteria bloom were applied to model remote sensing image and achieved remarkable results in monitoring cyanobacteria bloom in Lake Taihu.
