摘　　要：传统的单机判读服务系统,存在着判读标准不一、功能单一、插件依赖性高、系统集成性差等问题。在全面分析各类地理空间目标要素构成、地图表示方法和系统功能特点的基础上,对典型判读特征进行了归纳,完成了目标的分类、特征数据库的建立、平台总体架构的设计。基于HTML5和Web GL技术,构建了网络环境下多源、多尺度、多分辨率地理空间目标的三维判读一体化服务平台,实现了面向地理空间目标的判读、检索、三维显示及测试评定于一体的实用判读训练系统,为地理空间目标的网络判读提供了一定参考和借鉴。Most of the traditional single system for interpretation has disadvantages such as inconsistent standards, single function,dependence on plug - ins,and low - level system integration.On the basis of comprehensive analysis of the target element composition,map representation and similar system features, this paper summarizes the typical interpretation features and completes the object classification, the establishment of the feature library and the design of the platform overall structure.Then a 3D interpretation integrated service platform for multi - source,multi - scale and multi resolution geospatial objects is established based on HTML5 and WebGL.The platform realizes the practical interpretation training system,which integrates object recognition, retrieval, three - dimensional display and test evaluation and provides certain reference for network interpretation of geospatial objects.
