Paper Abstract

In traditional electronic government GIS (E-gov GIS), spatial data evaluation, examination and approval are dealt with by individuals, and the results are shared among collaborators in asynchronous mode. In order to improve the collaborative ability of E-gov GIS, a message-based synchronized cooperative GIS system (MSCGIS) is proposed in this paper. MSCGIS abstracts collaborators' GIS operations and encapsulates them into GIS command messages. And then the GIS command messages are passed and executed among related collaborators. Based on messaging, MSCGIS can realize the GIS synchronized cooperation of group. Some key issues are investigated in detail, such as the design scheme of MSCGIS, the encoding specification of GIS command message based on XML, and the interface and the collaborative process of prototype system. In a word, the construction idea of MSCGIS is sharing the GIS functions through passing collaborators' operations, rather than sharing spatial data among collaborators in traditional modes.
