| 摘 要： | 目前基于富网络应用的WebGIS平台已在多个领域得到了广泛的应用,但这些平台的地理事物多用户协同处理时效性不足,在地理业务流程中数据的共享与交互存在空间和时间上的限制。针对这一问题,本文提出了一种将REST(representational state transfer)架构与工作流技术应用到渭河水环境管理办公平台的解决方案。该方案利用ArcGIS Server中REST架构将空间操作返回的地图要素以字符串的形式表达以及工作流任务管理平台可传递字符串这一特点,对工作流任务管理应用进行二次开发,使其与ArcGIS Server REST架构结合,并应用于整个办公系统,以提高水环境管理中多用户协同工作的时效性,解决数据共享与数据交互的限制问题。从试验结果看,本文提出的方案与传统的水环境管理办公系统相比,该方案实现了多用户协同处理环境管理相关功能,降低数据互操作和数据共享等操作的时间和空间的限制,可有效增强WebGIS平台的办公能力,提高使用者工作效率。

Appl ication of REST and Workflow in WebGIS---Based on Weihe River Water Environment Management Office Platform |

| Abstract: | At present,the WebGIS platforms based on rich Internet applications have been widely used in many fields;However,those platforms have space and time limit in the interoperability of data sharing and data storage,and geographical multi-user collaborative processing is time-consuming.In order to solve these problems,the paper proposed a new plan,which applied the REST (Representational State Transfer) and workflow technology to the Weihe river water environment management office platform.The plan took advantage of the REST structure of ArcGIS Server software in which the return value of spatial operation is a stri ng and the fact that stri ng coul d be passed by workfl ow task management system.The pl an devel oped workflow for a second time and integrated it with REST structure,which was applied to office system to solve data sharing and data interchange restrictions and to improve the timeliness of multi-user collaborative work of water environment management;as a result,compared with traditional management system,the plan proposed in this paper can reduce the time and space constraints of data sharing and restrictions of interaction,effectively enhance the ability of coordination office for WebGIS platforms,and improve user work efficiency. |
