电子地图在县域地理空间信息平台的建设中具有重要作用。在分析传统电子地图发布主要以文件集的形式存储于服务器的不足基础上,探讨县域地理空间信息平台将电子地图以分布形式部署到各节点服务器中,利用瓦片金字塔技术来实现县域地理空间信息平台电子地图的网络发布,以达到电子地图的快速浏览和分节点存储数据的目的。通过地图瓦片、网络服务、地理信息服务技术,建立县域地理空间信息平台电子地图服务,为平台电子地图的数据发布与共享提供技术思路。
Electronic map plays an important role in the construction of county geospatial information platform. Based on the analysis of the traditional electronic map release mainly stored on the server in the form of file set, the paper explores the geo-spatial information platform of the county to deploy the electronic map to each node server in a distributed manner and uses the tile pyramid technology to realize the geo-spatial information Platform electronic map of the network released in order to achieve the electronic map of the rapid browsing and sub-node data storage purposes. Through the map tiles, network services, geographic information services technology, the establishment of county geospatial information platform for electronic map services for the electronic platform for the publication and sharing of data to provide technical ideas.
