水土保持监测系统信息平台实现方法(II)——平台更新维护系统

在水土保持监测系统信息平台实现参数库、模型库与数据库分开管理、空间数据与非空间数据集成存储于关系型数据库中的基础上,为了避免数据更新不及时或不完备而造成数据信息过时,导致信息平台变成死库,需要信息平台更新维护系统。基于这一目标,文章集中探讨了信息平台管理维护系统的结构、功能、实现方法和关键技术。其中系统结构在信息平台服务结构基础上采用C/S模式;开发平台采用ArcGIS桌面产品,以对象COM组件技术ArcObjects为平台、MicroSoftVisualBasic为开发环境,进行二次开发。从而集后台数据库和前端数据管理、更新维护于一体而实现了水土保持监测系统信息平台,也为水土保持监测系统成功运行奠定了坚实的基础。

Implementation of Information Platform of Soil ConservationMonitoring Information System(II)——Management System for Platform

On the support of the project of water and soil conservation monitoring system in the upper basin of Miyun reservoir,following with the implementation of the information platform,the management and update system for platform had bee developed.The paper expounds the objective,structure,functions,and the key technology of system in details.The main functions of the management and update system are to realize how to manage and update data,such as loading,editing,updating,deleting data etc.The system structure is based on C/S mode,and the developing platform has been adopted the desktop production of ArcGIS,that is ArcMap.With the COM technology,Arcobjects,and MS visual basic,the system has been completed and implemented.
