地上地下一体化校园三维地理信息系统开发研究

Development of 3D Geographic Information System for Integrated Underground and Underground Campus

国内校园一般具有人员流量大、建筑密度大的特点,作为校园重要基础设施的地下管线,与师生的学习、生活与工作息息相关。面向校园进行地上建筑与地下管线的三维系统可实现综合管网信息的整合、共享、更新、管理、分析和辅助决策,提升学校管理的信息化水平。本文以一个开发项目为例,完整地介绍建设地上地下一体化校园三维系统所涵盖的大比例尺地形图测绘、地下管线探测、精细化三维建模、地理信息系统开发等环节的关键技术、系统设计等,为建设地上地下一体化的三维校园提供参考。

The domestic campus generally has the characteristics of large flow of personnel and large density of buildings.As an important infrastructure of the campus,the underground pipeline is closely related to the study,life and work of teachers and students.The three-dimensional system for the campus building and underground pipeline can realize the integration,sharing,updating,management,analysis and auxiliary decision-making of the information of the comprehensive network,so as to improve the information level of the school management.This paper,taking a development project as an example,introduces the key technology and system design of the large scale topographic mapping,underground pipeline detection,fine 3D modeling,and GIS development,which covers the construction of the integrated campus and underground integrated campus three-dimensional system,for the construction of the integrated three-dimensional campus on the ground and underground.
