基于GIS+BIM技术的南宁市老旧小区微改造城市信息模型承载平台应用研究

Research on the Application of GIS+BIM Technology Based Urban Information Model Bearer Platform for Micro Renovation of Old Residential Areas in Nanning City

随着城市化进程的不断加快,居民的住房需求也日益增长,当前老旧小区的设施、环境已无法满足居民的生活需求,对老旧小区进行改造建设能够促进城市“新陈代谢”和健康发展。本文介绍了利用无人机倾斜摄影技术、GIS技术、BIM技术等建设微改造城市信息模型承载平台,平台可对实景三维模型、3DGIS大场景和BIM模型进行高效融合,实现模型实时检测、三维可视化分析等功能,为城市更新(旧改)工作提供可靠、便捷的三维可视化数据支撑。

With the continuous acceleration of urbanization,the housing demand of residents is also increasing.Currently,the facilities and environment of old residential areas are no longer able to meet the living needs of residents.Renovation and construction of old residential areas can promote urban"metabolism"and healthy development.This article introduces the use of unmanned aerial vehicle tilt photography technology,GIS technology,BIM technology,and other technologies to build a micro renovation urban information model carrier platform.The platform can efficiently integrate real 3D models,3DGIS large scenes,and BIM models,achieve real-time model detection,3D visualization analysis,and other functions,and provide reliable and convenient 3D visualization data support for urban renewal(old renovation)work.
