摘　　要：针对目前地质环境数据量大、管理应用方式落后等问题,采用面向服务架构技术、基于哈希格网改进的椭球四叉树空间索引技术、切片数据组织等关键技术,设计并实现了三维地质环境一张图服务系统,建立了标准化的、统一的地质环境数据库,初步搭建了地质环境数据中心。该系统充分考虑地质环境大数据的管理及应用,以遥感影像、数字高程模型等地理数据为基础,结合地质环境业务专题数据建立了地质环境综合数据库,在此基础上进行系统研发,实现了大数据三维一张图浏览、管理、统计查询、三维空间分析等功能。Aiming at the problems such as large amount of geological environment data and backward management and appli- cation, this paper designs and realizes service system of three-dimensional geological environmental in one map, based on ser- vice-oriented architecture technology, spatial indexing technology of ellipsoid quadruple tree based on improved Hash grid, data organization with slices and other key teehniques. A standardized, unified geologieal environment database is established, and geo- logical environment data center is also initially set up. This service system takes full account of the management and application of large data of geological environment. Based on geographic data such as remote sensing image and DEM, this paper establishes a comprehensive database of geological environment based on thematic data of geological environment business. On this basis, the system is developed and realized browsing, management, statistical query, three-dimensional spatial analysis and other functions in one three-dimensional big data onemap.
