一种基于WebGIS的网络地图数据采集方法研究

Research on the method of web-map data acquisition based on WebGIS technology

从互联网上快速获取庞大的旅游产业链数据,并及时更新,是一项有关旅游资源基础地理信息建库的技术难题。文中提出一种基于WebGIS的网络地图数据采集方法,利用网络地图服务商提供的API进行软件工具开发,通过地名搜索、可视范围搜索两种方式,基于Web信息对旅游接待设施的基础数据进行抓取,导出为XML文档。应用表明,该网络地图数据采集方法在旅游产业数据调查时,具有快速、高效的实用性。

Obtaining the great amount of travel-related industry data from the Internet and updating them are one of the technical problems in building a database for tourism resources of basic geographic information.A method of web-map data collection method is proposed based on WebGIS technology,using API provided by the web map service to develop the software tools,obtaining the tourism facilities information by name and visual search,and forming an XML document as result.The application shows that the web map data acquisition in the tourism industry serves to be fast,efficient and practical.
