宏观生态环境遥感监测系统是基于环境遥感监测应用技术的软件实现。本文重点介绍了宏观生态环境遥感监测系统的总体结构设计、业务流程设计和核心功能设计,以及模型转换与实现技术、实时投影转换技术与以文件和数据库相结合的数据管理技术、基于XML的数据实时交换技术、产品自动化生产技术等关键技术,并给出了系统的应用实例。系统应用结果表明,该系统符合我国宏观生态环境遥感监测业务应用模式,提高了环保部门生态环境遥感常规模式下的监测水平和紧急模式下的应急监测能力,将会在宏观生态环境遥感监测和评价服务中发挥重要的作用。
As global environmental issues become more and more prominent, remote sensing technology with large amount of information to monitor global environmental change has become an important manner. Macro-ecological environment remote sensing monitoring system is implementation of environment remote sensing applied technologies. The architecture of the system and the transaction flow diagram and its core functions are introduced. At the same time, the model transformation and implementation of technology, real-time projection conversion technology, a combination of file-based data and database management technologies, XML-based real-time data exchange technology, automated production technology are expatiated. The prototype system is constructed using .NET and IDL mixing programming language and its application examples are presented. System application results show that this system meets the remote sensing monitoring requirements using macro-ecological environment business applications model to improve the environmental protection department level under the normal mode and emergency capability under the emergency mode. This system can play an important role in the macro-environment remote sensing monitoring and evaluation.
