摘要
矿床资料是地质工作中重要的基础资料,为加速矿床信息资源开发利用,本文采用ArcGIS9.3技术,结合ASP.net与O-racle数据库,实现矿床资料在互联网上的共享、交换,更新与维护矿床空间及属性数据。设计了一种缓存技术,避免频繁访问服务器、硬盘和数据库;针对矿床资料数据量往往比较大的特点,将超过15M的文件,分块进行上传和下载;同时,对ArcGIS的核心技术-空间分析在本文中加以应用,对矿产资源进行科学预测和调控。
Ore deposit data is the important and basic data for geology work.In order to develop and utilize Ore deposit information resources more efficiently,the present paper attempts to use ArcIMS 9.3 as development platform to realize functions of WebGIS,based on B/S（Browser/server）,utilize ASP.net to write codes for updating and maintaining spatial data and attribute data,achieve share and exchange of Ore deposit data on internet.Designs a cache technology which can avod visiting a server,disk and database frequently.According to the large file of ore deposit,upload and download it by dividing it into parts.At the same time,this paper apply the core technology of ArcGIS to predict,regulate and control the ore resource.
