“…UAV also known as the Autonomous Navigation system because it is fly by using Global Positioning System (GPS) and support by the telemetry systems at the Ground Control Station (GCS) to monitor and navigate the UAV when capturing the data [5]. UAVs are becoming popular for use low budget and use in large scale mapping [6]. DJI Phantom FC40 used for this research as alternative ways for collecting data visually.…”

Abstract. The historical building is one of the country's heritage that needs to be taken care of failures in design and structure. Damage or dilapidation study that conducted by Conservation of Historical Building Guide Lines that practices for documentation any problems and defects in buildings. The stages to be followed to determine the damage was shooting photos for every element studied. Photo has been taken directly or by using stair for higher parts of structures. Inspection of the historical building should be emphasized to ensure that the building is in a safe condition for long periods. This research aims is to investigate the historical building defects by using Unmanned Aerial Vehicle (UAV) to identify the type of defects occur at the exterior structure of museum. The case study is building of Perak Museum that located at Taiping, Perak. The process involved in this study are planning and preparation before the flight, data acquisition using UAV, image processing and analyzing data from video to image. The result of analysis, a total numbers of 91 locations have been identified and documented suffer from defects or faults such as frame decayed, vegetation, perforated pipe and crack. All defects information obtained suing UAV visual inspection can help the museum maintainance team for conservation and maintainace work.

“…In recent years, space-borne and airborne remote sensing technologies have been developing rapidly and monitoring of topographic displacements and deformations, depending on construction activities or natural disasters has become possible by temporal change detection analysis. With the development of airborne laser scanning (ALS) technology, threedimensional (3D) description of the topographic surface became easier by means of very high resolution (VHR), rapid achievable and accurate point clouds that could not been provided by previous remote sensing technologies (Deng et al, 2007;Darwin et al, 2014;Höhle, 2017;Manfreda et al, 2018a). Considering high surface description potential, point cloud thought was adapted to photogrammetric image processing following ALS (Teizer et al, 2005;Rosnell and Honkavaara, 2012).…”

Nowadays, fast developing space-borne and airborne remote sensing technologies became indispensable for land related engineering disciplines such as mapping, geology, environment, mining and forestry. The new technologies, provide more qualified and rapid achievable outcomes, are adopted permanently. The description of the topographic surface became easier by means of very high resolution (VHR), rapid achievable and accurate point clouds acquired by digital photogrammetry and airborne laser scanning (ALS). Optical unmanned air vehicle (UAV), one of the most actual photogrammetric techniques, is much in demand for varied purposes. UAVs provide high resolution data using the advantage of lower flight altitudes. In this study, a construction activity and its environmental influences in Bulent Ecevit University Central Campus were monitored by an optical hand-made UAV. In the application, the temporal change was detected by generating contour-lines, digital terrain models (DTMs) and differential DTMs (DiffDTM) of the topography. By DiffDTMs, temporal changes on the topography were visualized in color height scale where the contour-lines presents the change of morphological structure.

“…These spatial databases can be the base of several studies (Darwin, et al, 2014;Bachmann, et al, 2013;Telbisz,et al,2011). These systems can be used for producing aer-ial-digital maps (Ahmad, 2011).…”

The use of the small format digital action cameras has been increased in the past few years in various applications, due to their low budget cost, flexibility and reliability. We can mount these small cameras on several devices, like unmanned air vehicles (UAV) and create 3D models with photogrammetric technique. Either creating or receiving these kind of databases, one of the most important questions will always be that how accurate these systems are, what the accuracy that can be achieved is. We gathered the overlapping images, created point clouds, and then we generated 21 different digital surface models (DSM). The differences based on the number of images we used in each model, and on the flight height. We repeated the flights three times, to compare the same models with each other. Besides, we measured 129 reference points with RTK-GPS, to compare the height differences with the extracted cell values from each DSM. The results showed that higher flight height has lower errors, and the optimal air base distance is one fourth of the flying height in both cases. The lowest median was 0.08 meter, at the 180 meter flight, 50 meter air base distance model. Raising the number of images does not increase the overall accuracy. The connection between the amount of error and distance from the nearest GCP is not linear in every case.
