Urban Digital Twin technologies expert evaluation for Green Spaces and Ecosystems

This data-set is a part of study for Building Digital Twin Scientific Conference 2025 titled "Urban Digital Twin Data Requirements and Reference Architecture for Green Spaces and Ecosystems". In this study 8 independent experts evaluated the commonly used technologies such as GIS, photogrammetry, LiDAR, 360 RGB photos, CAD, BIM, Infrared thermography and thermo-photogrammetry in relation to established KPIs for green spaces Urban Digital Twin (UDT). Expert ranking and Kendall's W calculation methodology was adapted to identify the most useful technologies for the UDT.

本数据集为2025年构建数字孪生学术会议（Building Digital Twin Scientific Conference 2025）中题为《面向绿地与生态系统的城市数字孪生数据需求与参考架构》（Urban Digital Twin Data Requirements and Reference Architecture for Green Spaces and Ecosystems）的研究的组成部分。本研究邀请8位独立专家，结合面向绿地的城市数字孪生（Urban Digital Twin, UDT）既定关键绩效指标（Key Performance Indicator, KPI），对地理信息系统（GIS）、摄影测量、激光雷达（LiDAR）、360° RGB全景照片、计算机辅助设计（CAD）、建筑信息模型（BIM）、红外热成像及热摄影测量等通用技术进行评估。研究采用经过适配的专家排序法与肯德尔和谐系数（Kendall's W）计算方法，以筛选出适配城市数字孪生的最具实用价值的技术。
