“…The accuracy obtained when delimiting the boundaries of cadastral plots using aerial images taken with UAS is close to the accuracy obtained by classical topographic measurements, some studies showing an accuracy of 10 cm (Deok-In et al, 2014), below 8 cm (Sang and Jae, 2016), 5 cm (Meouche et al, 2016) or less than 5 cm (Turner et al, 2017;Simon et al, 2018).…”

The importance of research in the field of topo-cadastral or photogrammetry has been revealed by many studies but strictly with reference to the general cadastre without considering the relevance for agriculture: arable land, pastoral space, forests or other uses. In this context, the purpose of the research was to bring "automated" alternatives, remotely, to the preparation, updating or completion of cadastral plans available in the past in analog format, at the level of each ATU. The working methodology consisted of: flying over the territory with WingtraOne photogrammetric equipment, at an altitude of 300 m, generating the orthophotoplan with very high spatial resolution (below 0.5 m), vectoring the lands according to the category of use, both in the urban area and outside the commune and the creation of geospatial databases. The obtained results materialized through the topo-cadastral inventory of all the buildings in the analyzed territory (arable land, pastures, hayfields, forests, built spaces, etc.), both as a spatial location (vector format) and as a descriptive database. The application of high precision photogrammetric techniques has a practical application in real estate inventory, especially in the case of large areas, but also a complement to theoretical research in various fields.

“…A surveyor is still required for professional responsibilities, however UAV's assist with quick on the go information only surveys, reducing the cost of hiring a surveyor [2]. The information extracted from a UAV survey is also near accurate with a satisfactory error of between 1cm for ground control points and 4cm for other parts of the survey [10].…”

Meeting planned timelines, quality and budget requirements in construction projects is always a challenge and the impact means that resources that should be used in other development projects get redirected to addressing the problems created by exceeding time, quality and cost aberrations. However, the fourth industrial revolution has not spared the construction industry and it is affecting the way infrastructure is delivered. According to the World Economic Forum, digital technologies have begun to change how infrastructure and the built assets are designed, constructed, operated and maintained. The entry of technology to the industry is also driven by the realization that in order to improve on the delivery of projects, adoption of innovative methods that are based on digital technology is essential as it ensures efficiency and effectiveness in project management, transparency, and record keeping. In this study, we report on the use of drones (Unmanned Aerial Vehicles-UAV) to capture site data and how it was integrated to Building Information Modelling (BIM) models to produce as-built drawings and quality checks from comparisons with as-imagined models. Data used in the study was obtained from construction projects sponsored by the Gauteng department of infrastructure, in South Africa. Findings demonstrate that UAV and BIM technology has the potential to improve the efficiency and effectiveness of project delivery. An enhancement in monitoring of work progress during construction, site surveillance, and integration of transformed 3D models to BIM to achieve more effective project management, record keeping, and quality control were observed. The accuracy of the data was also found to be adequate for the purpose of project management tasks.

“…Digital 3D models were constructed using the CRP data, which were used to restore the buildings. El Meouche et al (2016) researched the use of a UAV to mount a CRP system to survey the Tuekta burial mounds in the Russian Altay. The RMS error achieved was within 0.077–0.082 m.…”

Purpose The current technique used to measure construction is the conventional total station method. However, the conventional method is time-consuming and could not be used to create a photo-realistic three-dimensional (3D) model of an object. Furthermore, the Canseleri building is located at a slope. The paper aims to discuss this issue. Design/methodology/approach The aim of this study is to assess the geometric accuracy of a 3D model using unmanned aerial vehicle (UAV) images. There are two objectives in this study. The first is to construct a 3D model of the Canseleri building using UAV images. The second objective is to validate the 3D model of the Canseleri building based on actual measurements. Findings The close-range photogrammetry method, using the UAV platform, was able to produce a 3D building model. The results show that the errors between the actual measurement and the generated 3D model were less than 4 cm. The accuracy of the 3D model achieved in this study was about 0.015 m, compared to total station measurements. Originality/value Accuracy assessment was done by comparing the estimated measurement of the 3D model with the direct measurement. The differences between the measured values with actual values could be compared. Based on this study, the 3D building model gave a reliable accuracy for specific applications.
