摘要
网络地理信息服务将空间数据及基于空间数据的各类操作封装成单个实体,发布到Internet/Intranet上提供给We-bGIS应用系统的开发者,它便于WebGIS系统的更新拓展以及系统间集成和交互,对于解决目前WebGIS中存在的数据和操作难于共享的问题有重要意义。针对目前WebGIS构建过程中数据和操作难于共享等问题,提出了一套构建网络地理信息服务的思路,并以.net架构下基于GeoMedia WebMap Pro.的网络地理信息服务为例,在局域网内实现了网络地理信息服务的构建,最终将其应用到重庆市渝北区土地利用规划管理信息系统的建设中,为空间数据和操作的共享提供初步的解决方案。
The limitations of WebGIS emerge gradually along with its development, resulting in many difficulties in the sharing of spatial data and related operations. Therefore, the Web GIService in which spatial data and operations can be enveloped as self-governed entities for developers is proposed to solve these limitations. Consequently, when constructing WebGIS, developers only need to communicate with the interfaces provided by the service according to their specific demands. In this paper, a conceptual flow of building Web GIService has been put forward, and a corresponding service for LAN has been implemented based on techniques of GeoMedia WebMap Pro. under the architecture of . net has been taken as an example, in order to support the sharing of spatial data and operations.
