Investigation and Implementation of New Technology Wearable Mobile Laser Scanning (WMLS) in Transition to an Intelligent Geospatial Cadastral Information System
Yiğit, Abdurahman Yasin | Ulvi, Ali | Yakar, Murat
The human population is constantly increasing throughout the world, and accordingly, construction is increasing in the same way. Therefore, there is an emergence of irregular and unplanned urbanization. In order to achieve the goal of preventing irregular and unplanned urbanization, it is necessary to monitor the cadastral borders quickly. In this sense, the concept of a sensitive, up-to-date, object-based, 3D, and 4D (4D, 3D + time) cadastral have to be a priority. Therefore, continuously updating cadastral maps is important in terms of sustainability and intelligent urbanization. In addition, due to the increase in urbanization, it has become necessary to update the cadastral information system and produce 3D cadastral maps. However, since there are big problems in data collection in urb...
Su Altı Yapılarının 3B Modellemesi ve Dokümantasyonunda Kullanılan Video ve Fotoğraf Çekimi Yöntemlerinin Karşılaştırmalı Analizi
Yiğit, Abdurahman Yasin | Ulvi, Ali | Yakar, Murat
Su altındaki bir cismin üç boyutlu olarak belgelenmesi ve dijital platformlara aktarılması son yıllarda önem kazanmıştır. Bu amaçla fotogrametri yöntemi su altında denenmiş ve sualtı fotogrametrisi terimi literatürde kendine yer bulmuştur. Fotogrametri yönteminin tercih edilmesinin en önemli nedeni geleneksel yöntemlere göre daha kısa sürede veri üretimi, zaman ve maliyet açısından olumlu katkı sağlamasıdır. Ancak su altında fotografik veri toplayan dalgıçlar su altında sınırlı bir süre kalabildikleri için fotoğraflama işlemi tekrarlanmakta ve süreç uzamaktadır. Bu olumsuzluğu en aza indirmek için video çekim yöntemiyle veri elde etme çalışmaları denenmeye başlanmıştır. Bu çalışmada, bir havuza test amaçlı obje yerleştirilerek hem fotoğraf çekim hem de video çekim yöntemi ile üç boyutlu mo...
Combination of Terrestrial Laser Scanning and Unmanned Aerial Vehicle Photogrammetry for Heritage Building Information Modeling: A Case Study of Tarsus St. Paul Church
Yiğit, Abdurahman Yasin | Ulvi, Ali | Fidan, Şafak
Cultural heritage building information modeling (HBIM) is an emerging process allowing us to reconstruct built heritage virtually. The data of a digitally documented cultural heritage building offers significant advantages as it is accessible and modifiable by all professionals involved in the same or different projects. The most important factor affecting the accuracy and precision of the HBIM model is the ability to collect complete and accurate information about the physical structure. Combining terrestrial laser scanning (TLS) and unmanned aerial vehicle (UAV) photogrammetry point clouds is one of the most efficient ways to capture accurate digital data on the building. This study provides the foundation for creating an HBIM model for cultural heritage the coupling of spatial data with...
Assessing the Effectiveness of UAV Photogrammetry, Terrestrial Laser Scanning and iPad LiDAR for Complex Cultural Heritage Sites Documentation and WEB-Based VR Visualization
Ulvi, Ali | yiğit, Abdurahman Yasin
Avdalaz Castle, carved by the Phrygians around the 2nd–3rd century bc in Afyonkarahisar, western Türkiye, and later reused during the Roman and Byzantine periods, represents one of the earliest known multi-storey rock-cut settlements in Anatolia. Beyond its architectural uniqueness, the site holds exceptional cultural and historical importance for understanding early urban dwelling patterns in central Anatolia. However, its irregular geometries, multilevel interior chambers and limited accessibility pose significant challenges for accurate digital recording and long-term preservation. To address these challenges, this study undertakes a comparative assessment of UAV photogrammetry, terrestrial laser scanning (TLS) and iPad LiDAR scanning (iLS). UAV photogrammetry enabled rapid coverage of ...

Fusion of IPAD Pro LiDAR and SfM-Based Photogrammetry for 3D Documentation of Cultural Heritage
Ulvi, Ali
Digital documentation of cultural heritage has experienced significant growth in recent years, primarily due to technological advancements in computer science. Documentation studies rely on photogrammetry and laser scanning, which are becoming increasingly practical and efficient. However, since these data collection methods cannot always produce complete and complete data, data fusion is necessary to meet the requirements. SfM-based photogrammetry is a data collection technique widely accepted in documentation studies due to its practicality, speed, and cost-effectiveness. Additionally, recent technological advancements have led to the emergence of low-cost LiDAR systems, such as Apple’s iPhone (starting from 12 Pro) and IPAD, making research more cost-effective. For this study, three cul...
