基于Gridmap的地图快速浏览系统设计与实现

Study and implementation of Gridmap-based fast map browsing systems

本文先分析了传统国土资源数据共享中存在的问题,然后介绍瓦片地图技术及其瓦片金字塔建模,设计了基于瓦片地图技术的国土资源浏览系统。系统结构采用B/S模式,充分利用Gridmap技术、XML技术以及AJAX技术,将矢量地图和栅格影像数据转化为静态图片进行统一管理,实现了部门之间的数据快速共享浏览与空间信息查询等。

This passage first analysis the traditional land resources data sharing problems,and then introduces tile map technology and pyramid modeling,to design browsing system of land and resources based on tile map.System structure adopts B/S mode and makes full use of Grid map technology,XML technology and AJAX technologies to make the vector map and raster image data into a static image for unified management,to achieve the rapid sharing of data and query of spatial information between departments.
