基于网络地图切片的地图服务实现与应用

Implementation and Application of Map Service Based on Web Maps Tiles

随着公共基础地理信息服务平台的建设,网络地图的服务内容也越来越丰富,然而受制于因特网和建设成本的限制,很难将互联网地图服务移植到局域网环境中。本文分析网络地图服务的切片请求方式和ArcGIS Server软件的切片组织形式,借助于ArcGIS Server软件将Web墨卡托(Web Mercator)投影的网络地图切片下载缓存到本地服务器上,将其发布成局域网内的地图服务,为快速搭建局域网地理信息系统提供了一种新的尝试方式。

With the construction of public infrastructure geographic information service platform,services of web maps are increasingly rich,but subject to the limitations of the Internet and construction costs,it is difficult to move the Internet map service to LAN environment. This paper analysis request tiles from web maps and tiles organizational of Arc GIS Server software,use Arc GIS Server download and cached the Web Mercator projection of the Web Map Tiles to the local server,to publish a map on the LAN services in order to provide the method for quickly build a LAN geographic information systems.
