Cultural Heritage Through Time (CHT2)

从景观到建筑尺度，时间研究是文化遗产研究变化调查的核心。时间分析和多时间三维重建是保护和维护各种形式文化遗产的基础。这些研究构成了任何有关干预文化遗产的决定的基础，有助于评估所涉及的风险和问题。CHT2项目的目的是将第四维度（4D）充分融入文化遗产研究中，以分析建筑和景观的时间。CHT2将收集异质材料（多时相航空和地面照片、地图、图纸等），并将其与当代3D模型相结合。这些地理参考和度量产品将成为定量分析领土转换或建筑变化、可视化目的、保护政策、未来规划或可能的商业应用的基础。因此，CHT2将制作从景观到建筑尺度的时变3D产品，以设想和分析由于人类活动或干预、污染、战争、地震或其他自然灾害而失去的场景或可视化变化。对于景观，将有可能按时间顺序突出变化，并调查城市化如何影响变化。对于城市来说，随时间变化的3D模型将允许重新发现丢失的区域或建筑物。最后，对于建筑或建筑物，从实际情况的三维模型出发，突出变化，并根据历史信息重建缺失的部分。在合作伙伴的支持下，项目完成所需的各种信息将从国家博物馆和档案馆中寻求。最后的项目展览计划展示为不同案例研究生成的随时间变化的3D产品。CHT2项目将依靠一个跨学科的国际联盟，以利用3D建模、数据集成、景观考古、地理信息系统、文物保护和保存等领域的领先专业知识。

Temporal studies are central to cultural heritage research for the investigation of change, from landscape to architectural scales. Temporal analyses and multi-temporal 3D reconstruction are fundamental for safeguarding and maintaining all forms of cultural heritage. Such studies form the basis for any kind of decision regarding intervention on cultural heritage, helping assess the risks and issues involved.The aim of the CHT2 project is to fully integrate the fourth dimension (4D) into cultural heritage studies for analysing structures and landscapes through time. CHT2 will collect heterogeneous material (multi-temporal aerial and terrestrial photographs, maps, drawings, etc.) and combine it with contemporary 3D models. These geo-referenced and metric products will be the basis for quantitative analyses about territory transformations or architectural changes, visualization purposes, preservation policies, future planning or possible business applications. Therefore CHT2 will produce time-varying 3D products, from landscape to architectural scale, to envisage and analyse lost scenarios or visualize changes due to anthropic activities or intervention, pollution, wars, earthquakes or other natural hazards. For landscapes it will be possible to chronologically highlight transformations and investigate how urbanization influenced change. For cities, time-varying 3D models will allow the rediscovery of lost areas or buildings. Finally, for architecture or buildings, starting from a 3D model of the actual situation, changes will be highlighted and missing parts will be reconstructed based on historic information. The heterogeneous information necessary for the project's accomplishment will be sought from national museums and archives with the support of the associate partners. A final project exhibition is planned to show the time-varying 3D products generated for the different case studies.The CHT2 project will rely on an interdisciplinary and international consortium in order to exploit leading expertise in the fields of 3D modelling, data integration, landscape archaeology, GIS, heritage conservation and preservation.
