摘　　要：本文系统论述数字海淀智能管理信息系统基础信息平台 (简称“数字海淀”)构筑的目的、技术要求、设计思想和实施的技术方法。“数字海淀”首次采用具有直观、真实感强、易于操作的特点的 1∶ 2 0 0 0比例尺彩色航空影像平面图作为搜索平台。同时通过小波压缩技术 ,将 2 8GB的海量数据压缩能在个人电脑或便携机上运行。“数字海淀”This paper discusses the purpose,technical need,design idea and implement method of the construction of basic information platform of information system of intellect administration of Digital Haidian. The basic information system platform of Digital Haidian employ first 1∶2000 scale of colour air photo map as a hunting engine that possess the features of directly perceived through the senses,strongly sense of reality and simply operation. At the same time, a 25GB of great capacity data is compressed by advanced wavelet compressive technique. So that Digital Haidian can works well in personal computer or packet one. The model of Digital Haidian, at present, can provide constructive reference of information system for administration of city in China.
