Advanced LiDAR Atlas Akademi en-US Advanced LiDAR 2791-8572 Detection of Informal Housing and Non-Complıance with Planning Regulations from Maps Produced by Mobile Lidar Technique <p>With the increasing population, cities are constantly changing and developing. Therefore, it is difficult to monitor and control rapid changes in cities. Therefore, planning is very important in terms of controlling these dynamic cities and ensuring regular and planned settlements. However, buildings may not always be built in accordance with the plan and may be built against the zoning law. These structures, which are built against the plan, can distort the city's silhouette, cause unplanned construction and restrict people's access to some services. It is also important that the building detection process, which is needed in many areas from population movements to city development, from illegal building surveillance to casting extraction, is accurate and automatic. With the development of Remote Sensing and Geographic Information Systems (GIS), new methods have been used to detect such structures. One of these methods used is the detection of these structures with high resolution data. In this research, the building detection by using point clouds data obtained from Light Detection and Ranging (LiDAR) system with satellite images.</p> Serhat Güneş İsmail Şanlıoğlu Copyright (c) 2022 Advanced LiDAR 2022-09-30 2022-09-30 2 2 31 35 Analytical Documentation of Stone Material Deteriorations on Facades with Terrestrial Laser Scanning and Photogrammetric Methods: Case Study of Şanlıurfa Kışla Mosque <p>Şanlıurfa Kışla Mosque, in its geographical context, is of great importance with its historical importance and architectural features as it reflects the tangible and intangible cultural heritage. However, it is seen that the structure is worn out due to various factors and is exposed to various material problems. In terms of the continuity of the cultural heritage, it is necessary to determine the material problems before the destruction of the building, to document it and to take precautions for protection. The aim of the study in this context is to detect and analytically document the material deterioration on the facades of Şanlıurfa Kışla Mosque. As a method in the study; observational detection and terrestrial laser scanning technique were used. The results of the study support the fact that the method used provides great savings in terms of time and effort in the production of architectural drawings and damage maps, which is the result obtained in many studies in the literature. In addition, as a result of the study, it was determined that the most common type of material deterioration in the building was surface pollution. In the geographical context determined by the study, it is expected to detect the dangers related to stone structures and to take measures to prevent the hazards related to the structures.</p> Lale Karataş Aydın Alptekin Murat Yakar Copyright (c) 2022 Advanced LiDAR 2022-09-30 2022-09-30 2 2 36 47 Detection of Road Distress with Mobile Phone LiDAR Sensors <p>Comfort and safety on urban roads are two important and desirable factors in road transport networks. When it comes to providing road comfort, potholes, which emerge on the road surface for different reasons, are one of the problems that we do not want to encounter in our daily transportation. Although different techniques are already being applied to detect deformations on road surfaces, developments in measurement technologies gradually bring alternative techniques with them. The best example for this are the small size LiDAR sensors which have newly been added to mobile phones, and the subject of this study is whether they can be used in detecting such problems. The data collected from the field survey enabled a detailed examination of the road potholes with the proposed methodology based on region growing and plane fitting. According to the results, the 3D sensor technologies will take a new place in measurement technologies by providing high dense data and visualisations in small-sized projects, thus facilitating instant decisions. In the study, potholes on the road surface were determined with 4 different data sets obtained in Denizli province Pamukkale district Karahayıt neighbourhood and detailed information about their characteristics was collected. As a result, with this study, the LiDAR sensor released to the market by Apple on iPhone 12 and following versions has developed an alternative measurement technique and methodology that can be used in the implementation of small-sized projects on road surfaces. It is clear that the use of mobile phone-based LiDAR sensors in road repair services has significant potential in the near future.</p> Mustafa Zeybek Dilay Ediz Copyright (c) 2022 Advanced LiDAR 2022-09-30 2022-09-30 2 2 48 53 Creating Architectural Surveys of Traditional Buildings with the Help of Terrestrial Laser Scanning Method (TLS) and Orthophotos: Historical Diyarbakır Sur Mansion <p>Manual mapping or traditional methods of architectural documentation by an expert in historical buildings are today considered time-consuming and laborious procedures. In recent years, with the development of technology, the use of digital tools to support architectural documentation activities has provided more detailed results on architectural analysis and has simplified processes which were performed manually. The Historical Sur Mansion, located in the Diyarbakır urban protected area, which is the subject of the study, is a historical building that reflects the general characteristics of traditional houses in Diyarbakır, containing its own characteristics, formed by factors such as topography, materials, climate as well as cultural elements in the immediate environment. The building has been registered as a "monumental" structure to be protected by the Council of Europe's Natural and Cultural Heritage Conservation Inventory and the General Directorate of Turkish Cultural Heritage and Museums. The decorations and inscriptions on the iwans, window and door openings of the building are examples of Diyarbakır residential architecture. The aim of the study is to obtain the analytical surveys of the historical Sur Mansion, which is a great necessity for the sustainability of the cultural heritage in the region, by using orthophotos produced by various techniques from laser scanning as a base. Researches carried out on the studied area have shown that by using the orthophotos produced from the data obtained from terrestrial laser scanning as a base, data with sufficient level of detail needed in architectural documentation can be obtained today, and this method offers an economically effective and fast solution to produce analytical surveys.</p> Lale Karataş Aydın Alptekin Murat Yakar Copyright (c) 2022 Advanced LiDAR 2022-09-30 2022-09-30 2 2 54 63
