县域地理空间信息平台电子地图发布与共享的方法

A Method of Release,Sharing of Electronic Maps in County Geospatial Information Platform

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 county Geospatial Information platforms.Traditional electronic maps are stored on server computer in file sets,which leads to the hard release and sharing process of maps.This paper presents a method of electronic map release and sharing in County Geospatial Information Platform.In the method,electronic maps are distributed in different server computers at different platform nodes;meanwhile,tile-pyramid is used to realize web release of these electronic maps,which makes the map scanning fast and fluent.In conclusion,map tiles,web services as well as geographic information service techniques offer a new path in electronic map release,sharing of County Geospatial Information Platform.
