基于插件技术的滩涂资源遥感监测系统的研究与应用

可视化滩涂资源遥感监测系统有利于科学监测和保护滩涂资源.针对目前的滩涂资源遥感监测系统存在空间和属性信息关联不足、系统复用性和可扩展性不高等问题，本文结合滩涂资源的可视化展示需求，对系统进行优化：在GIS实体管理方面，提出了基于GML的映射设计思想和面向对象的设计原则，实现了GIS对象及属性的动态管理；在图层管理方面，提出了基于MapObject组件的GIS实体展现，实现了多种矢量数据和栅格数据的转换；在系统设计方面，采用插件技术，实现了系统功能的封装和复用.系统较好地实现了对江苏沿海滩涂资源的动态监测和可视化展示，对于海洋滩涂资源的保护和服务海洋高质量发展都具有重要的意义.

Research and Application of Remote Sensing Monitoring System for Tidal Flat Resources Based on Plug-in Technology

The visual remote sensing monitoring system of tidal flat resources is conductive to their scientific monitoring and protection. However, the current remote sensing monitoring system of tidal flat resources has some problems, such as insufficient correlation of spatial and attribute information, low system reusability and scalability. Combined with the visual display requirements of tidal flat resources, this study optimizes the system. In the aspect of GIS entity management, this paper puts forward the mapping design idea and object-oriented design principle based on GML, which realizes the dynamic management of GIS objects and attributes. In the aspect of layer management, a GIS entity presentation based on MapObject component is proposed to realize the conversion of various vector data and grid data. In the aspect of system design, the plug-in technology is used to realize the encapsulation and reuse of system functions. The dynamic monitoring and visual display of Jiangsu coastal tidal flat resources are well realized, which is of great significance for the protection and the high-quality development of marine tidal flat resources.
