通过Google Maps API开发实现对兴趣点的抓取,以Oracle Spatial点对象字段实现存储,借助Oracle Maps开发WebGIS系统,实现Google Maps兴趣点数据快速抓取,并与对应的属性和地图符号在Oracle中一体化存储,最终实现同数据库中已有的矢量和栅格数据的叠加和集成发布.对桂林市漓江流域旅游资源空间数据构建进行应用实践,结果表明:该系统可帮助开发者快速构建集兴趣点位置、属性、显示符号为一体的空间数据库,大大缩短开发周期并有效降低开发成本.
The point of interest (POI) grabbing is realized by using Google Map API, then data is stored in term of point type provided by Oracle Spatial. With the aid of Oracle Maps, a WebGIS system is subsequently developed for the pur- pose of fast POI grabbing and integrative storage of POI data, as well as its corresponding properties and SVG symbols. Application has been carried out for the Lijiang River Vally tourism resources in Guilin city. The results show that the system can help developers to construct Spatial database very quickly, which combines the location of POI, properties, as well as the displaying symbols. Additionally, it is effective to shorten development cycle and reduce the system cost.
