ArcGIS Server缓存图片提取程序的设计与实现

Design and Implementation of Cache Pictures Based on ArcGis Server Extraction Program

缓存切片技术已经成为网络地理信息系统(WebGIS)地图发布的主流。本文介绍了基于主流的ArcGIS Server平台缓存切片的原理和特点,利用VB结合ArcObject设计开发一个可以从ArcGIS Server建立好的缓存图片中提取目标区域的缓存图片的自动化工具。

The Map Cache technology has already been the mainstream of WEB GIS-based mapping distribution currently.This paper presents the principle and distinctive features of cache pictures based on ArcGis Server,and a well-worked tool has been designed and developed used Visual Basic（VB） combined with ArcObject,which could extract the target from established cache pictures.
