Digitally preserving Hukuru Miskiy

作者：Reka Vasszi

A team of surveyors, programmers and heritage professionals are on a mission to unfold and virtually document the secrets behind the construction of the most important heritage site of the Maldives – the Malé Hukuru Miskiy.

The Malé Hukuru Miskiy, meaning the Friday Mosque, is located on the capital island of Malé in the Maldives and currently is included in the UNESCO World Heritage tentative list. To meet UNESCO’s standards and become part of the final World Heritage list requires the详细的文档of the mosque complex and additional conservation and refurbishment work.

Through centuries, no information or drawings have survived to describe the complex design and construction of the site and its structures, hence, the Department of Heritage of the Maldives askedWater Solutions Pvt Ltd. to capture and document the heritage complex in 3D.

Water Solutions provides surveying, engineering and environmental consultancy services across the Maldives. The company strives to introduce new technologies and state-of-the-art equipment to improve its surveying services. To undertake a precise digital survey that would be the basis forHukuru Miskiy的3D文档和翻新, Water Solutions used laser scanning in combination with a total station and theworld’s fastest GNSS RTK rover.

“Hukuru Miskiy is a historically and architecturally significant place; the work carried out by Water Solutions to digitise the mosque is priceless,”said Yumna Maumoon, minister of arts, culture, and heritage in the Maldives.

Scanning the largest coral stone building in the world

Hukuru Miskiy was built in 1658 under the reign of Sultan Ibrahim Iskandar. This mosque complex, the largest and finest coral stone building in the world, is a testimony of the fusion of Indian Ocean seaborne cultures and proof of the unique artistry of the Maldivian people.

用于建造Hukuru Miskiy的材料和技术在马尔代夫古代建筑技术中展示了一个重要的阶段。为了保存这种文化遗产和荣誉，遗忘了马尔代夫的工艺，捕获并获得了地理位置的Hukuru Miskiy的水解决方案in only a couple of days, using a combination of Leica Geosystems solutions:

• Leica BLK360imaging laser scanner
• Leica Viva TS16机器人总站
• 莉卡GS18 tGNSS RTK ROVER
• 莉卡Cyclone REGISTER 360三维激光扫描点云注册软件e.

“Surveying is something I do with great passion. I love the technology and the sense of adventure that comes with working outdoors. Leica Geosystems has been innovating and changing the game with their latest surveying gear. Collecting data for this project in such detail has made this an exciting oneWater Solutions Pvt Ltd.的离岸测量师Mohamed Affan Shakir说。

混合技术

The heritage site consists of the mosque surrounded by a 17^Th-century cemetery and a minaret. The sanctuary complex is still used to conduct the daily prayers, thus the team had limited time to scan the building. Besides, the many small rooms, the detailed carvings on the walls and the narrow loft encumbered the documenting process.

Water Solutions required a紧凑的产品That would capturescans fast with high-resolution imagesand can alsofit in small placesto document the fine details. With these challenges in mind, the team selected the BLK360 to capture the mosque, its roof structure, the cemetery and the minaret.

为了引用扫描目标，TS16机器人总站以非晶和模式使用来直接测量目标的坐标。为了求解最后一个点云，GS18 tGNSS RTK ROVERwas used to establish control points on site. Finally, the point clouds were transferred and post-processed inCyclone REGISTER 360三维激光扫描点云注册软件e.

“We put our trust in Leica Geosystems surveying equipment to collect accurate data and never had any issues with the equipment. It is vital to have a gear that you can rely on when carrying out surveying in any outdoor environment,” said Hamdulla Shakeeb, laser scanning expert at Water Solutions Pvt Ltd.

Pushing the boundaries of heritage preservation

该数字数据集的创建可以帮助保留它，而不是350年历史的遗产并且详细的拟建地图可用于修复屋顶结构和基线图，以备将来修复。详细3D models allow heritage professionals to document, manage, renew or maintain Hukuru Miskiyand qualify the site for the final decision on its inscription on the World Heritage list.

“Using Leica Geosystems equipment has strengthened the confidence with our clients, helping to build long-lasting business relations,”沙基尔说。

除了遗产的物理保存外，激光扫描可以开发小型3D模型或虚拟现实应用程序向学生传授马尔代夫历史，工艺，传统建筑和古老的建筑技术。

The BLK360, in combination with the total station and GNSS RTK rover, enabled Water Solutions to introduce laser scanning in the Maldives for the first time and showcase the potential of laser scanning to survey and document heritage sites.
