| 摘 要： | 由于操作对象为地理要素的协同减灾系统,不同地域、不同专业的各位专家,对同一张底图中要素编辑过程中出现的编辑冲突并发问题,提出一种基于ArcGIS要素属性字段的解决方法。通过增添一个属性字段和加锁法相结合的方法,实现了更加高效、灵活友好的并发控制策略。

| Abstract: | For the collaborative disaster reduction system in which the operation object is a geographical element,experts from different regions and different professions propose a solution based on the attribute field of ArcGIS elements for the problem of editing conflicts in the editing process of elements in the same base map.By adding a combination of attribute fields and locking methods,a more efficient,flexible and friendly concurrency control strategy is realized. |
