摘要
面对灾害,快速实施异地专家协同标绘并及时制定救灾方案意义重大。针对这一问题,该文实现包含多专家间信息传递和标绘重现等功能的协同标绘系统。系统结合ArcGIS中版本更新的模式,采用"单人单版本"模式的数据编辑和更新模式,通过增添离线模式的灾情标绘策略,解决因网络故障或其他突发情况导致的标绘中断问题。实验结果表明,该设计能更加全面高效地为异地专家及时制定救灾方案提供保障。
Natural and public security disasters occur frequently in China,and in the face of disasters,it is of great significance to quickly implement the collaborative mapping of experts from different places and to formulate disaster relief plans in a timely manner.In response to this problem,this paper is based on ArcEngine development to achieve a collaborative plotting system that includes multi-expert information transfer and plot reproduction.In order to improve the collaborative mapping efficiency of the system remote experts,the system data update mode combines the replication,synchronization and version management functions of the ArcSDE geodatabase to learn the version update mode in ArcGIS,and adopts the data editing and update mode of the 'single person single version' mode.A data update mode combining online data update mode and offline data update mode is proposed.By adding an offline mode disaster mapping strategy,the problem of off-site expert mapping interruption caused by network failure or other network emergencies is solved.The experimental results show that the design of the data update mode can effectively reduce the dependence on the network in the process of system collaborative plotting,and provide more comprehensive and efficient protection for the disaster relief plan for off-site experts.
