摘要: "同一个地质"(OneGeology)计划是一项旨在建立全球大约1:100万比例尺的地质图数据库,使地质图数据可以在互联网上共享的国际合作计划."OneGeology"计划是一个基于WebGIS技术的分布式系统,每个提供数据的组织者在自己的Web服务器上管理数据,"OneGeology"门户网站和每台Web服务器进行联接并可以显示这些信息.本文以构建中国1:100万地质图网络地图服务(WMS)为例,研究了MapGIS格式的数据实现WMS网络地图服务的方法、流程.对此,本文选择了开源软件MapServer WebGIS平台和Apache Web服务器实现WMS服务.MapServer可以发布Shape文件,因此需要将MapGIS文件转换为ArcGIS的Shape文件.由于系统库不能跨平台使用,必须在ArcGIS平台下建立中国1:100地质图系统库,系统库包括Point(点)、Line(线)、Polygon(面)三种符号类型,并根据属性信息重新对空间图形数据进行符号化.MapServer通过Mapfile配置文件定制网络服务,该配置文件是地质图数据发布的核心内容,文件内容包括地图服务的数据源、数据输出格式、符号化方式、元数据信息等,采用文本方式存储.最后,通过在"OneGeology"门户网站注册,提供网络地质图服务.

Abstract: "OneGeology" is an international cooperative project which makes it accessible to share the geological map database on the internet aiming at creating a global geological map database at the scale about 1:1000 000. "OneGeology" system is a distributional system based on WebGIS technology. Every data provider can manage their data on their own Web server. The "OneGeology" portal accesses all of distributed web servers and displays the information. In this article, we took setting up of China 1:1000 000 geological map Web Map Service (WMS) as an examlpe, and implemented the methods and flow of WMS based on the research on MapGIS formate data. There are multi-methods to implement WMS. We used open sources MapServer and Apache software to serve our WMS. MapServer can publish ESRI'S Shapefile, so we need to transfer MapGIS file into ESRI'S Shapefile. Because symbol system library in MapGIS including 3 types (point, line, polygon) can not be used in ArcGIS platform, it must be built in the ArcGIS platform and symbolise the spacial data according to the attribute data. MapServer configures its web services by text configuration called "mapfile", which is the major delivering contents of geological map data and includes map service data sources, data output format, symbolizing type, and metadata information, etc. At last, each provider registers in "Onegeology" potal to offer serves for WMS.

Key words: OneGeology, geological map, WMS, data sharing
