Advancing geomatics techniques for heritage restoration

Author: Reka Vasszi

现代地理技术，例如激光扫描，3D建模和摄影测量法正在对文化遗产领域越来越感兴趣。这些最先进的技术获取的所有数据都可以存储在数字建筑信息模型（BIM）数据库中。包括有关建筑特征的所有方面和信息，例如几何形状，材料和恢复需求，BIM模型可以支持任何维护计划和对古代建筑的可持续保护。

不可避免地要使用现代方法和设备来培训未来一代的传统保护者，这是不可避免的。Dharatal是一家专注于遗产保护和可持续发展的建筑工作室，以及印度国家艺术和文化遗产信托基金会（INTACH）的比利时分会与Madhya Pradesh旅游合作，促进了在文化遗产的文献中使用先进技术。为期五天的研讨会的参与者对拉杰纳加尔（Rajnagar）进行了调查，拉杰纳加尔（Rajnagar）是一个历史悠久的小镇，在印度的Khajuraho附近，他以其文化和建造遗产而受到赞扬。

The workshop aimed to combine geomatics techniques and restoration methods for interdisciplinary knowledge and support the preservation and documentation of the fort complex of Rajnagar and the historic gardens of Orchha. The students participated in first-hand activities using a variety of Leica Geosystems’ equipment and software to learn the documentation process. The participants learned how to:

• 使用Leica Flexline TS06total station and the Leica VivaTS11manual total station.
• Capture the ancient buildings with the Scanstation P20 andP40High-Definition 3D laser. scanners Post-processed the data using气旋3D点云处理软件和Infinitysurvey software.

“I had a wonderful experience in this workshop. It was overall very well-managed and I learned how to combine geomatics and restoration techniques to preserve cultural heritage,”said Ar. Sanjukta Das, assistant professor at DY Patil technical institute.

Exploring the lost gardens of Rajnagar and Orchha

Khajuraho地区是一个全球著名的旅游胜地，可追溯到9号的寺庙^Thto 12^Thcentury. The temple group of Khajuraho is one of India’s most popular UNESCO World Heritage Sites and the region is also gaining more recognition for the neighbouring fort and royal gardens of Rajnagar and Orchha.

Rajnagar was a residential town of the royal families of Chhattarpur, where besides the royal palace and fort, several monumental gardens were built in the second half of the 18^Thcentury. The history of these gardens is unknown, as archives do not exist and the oral tradition is also scarce about the majestic gardens of the Maharaja. The preservation of the lost gardens of Rajnagar ─ as it refers to the limited scientific knowledge about the gardens ─ was taken up by the Belgian chapter of INTACH to restore and to turn the gardens into training centres for sustainable and organic agriculture as well as promote sustainable tourism in the region for the benefit of the local population.

The project is part of a renovation strategy for the development of Khajuraho and the broader region. The first step of the project was to document all architectural features of the site, create 3D models and a digital database to plan a historically and scientifically informed reconstruction of the fort and the royal gardens. The workshop was open to students who wanted to deepen their knowledge on geomatics methods and modern technology applied in heritage preservation.

“ Rajnagar的研讨会是其中之一 - 针对建筑师和建筑专业学生的数字文档培训，”said Ar. Jivantika Satyarthi, assistant professor at SPA.

训练The future generation of heritage conservators

During the first week of the workshop 29 students were trained with Leica Geosystems total stations and the Leica P-series 3D laser scanners. The participants could learn how to survey and document historical buildings, in this case, the fort of the younger brother of the ruling maharaja of Chhattarpur.

The result of the 5-day intensive course was a detailed point cloud, a 3D model of the fort complex and a master plan of future conservation work.

From digital realities to historic preservation

在研讨会的第二周，专业人士记录并进行了对Orchha花园的条件评估。Intach Belgium和Madhya Pradesh旅游委员会都介绍了该文件。精心设计的结果有助于为遗产结构和花园制定未来的保护管理计划。

“ Orchha Gardens的精彩文档和未来重建作品的非常好的基础”stated Om Prakash Misra, senior consultant of Madhya Pradesh tourism board.

通过现代设备和方法培训下一代的测量和遗产专业人员，在遗产保护方面开辟了新的视野 - 从数字现实的计划到在现场采取行动。
