“…The control points were selected and installed in front of the interface using the device Global Positioning System "GPS" Trimble R4 shown in Figure 1. Which will be processed free online and choose the best free online processing site [19]. The coordinates of the control points (x, y, z) that were installed in front of the interface were known and then the device Topcon IS-03 Robotic Imaging Total Station shown in Figure 2 was installed, to start the scanning process after balancing the device and inserting the control point and the Back-sight point (B.S) whose coordinates are known in advance.…”

Modern technology has radically altered documentation and has promised to do so again. Photographic and non-photographic documentation tools are combined into a single operation in which digital imaging technology is the mainstay. 3D support is still not popular among users involved in documenting the facades of modern buildings or important historical sites. This is a very important technique nowadays for (memorizing, preserving, restoring, and protecting) the facades of modern buildings or historical sites that need restoration and continuous follow-up. Cost and time play a vital role in the quick development of documentation strategies and tools to provide a true comparison between these methods. Surveyors can now complete projects with unprecedented precision because of advancements in hardware and software technology. For their daily activities, surveyors now rely on contemporary electronic instruments such as total stations and GPS. When conducting work, the surveyor always chooses the most appropriate equipment and the most cost-effective method of completing it. There are numerous microchips on the market nowadays. Surveyors can benefit from tools like GPS, complete bot stations, and digital levels. Over time, large, expensive survey equipment has been replaced with the smallest, most powerful equipment available. For example, the 3D ground laser is a highly expensive piece of equipment due to the high cost of the laser scanner. An alternative technology has been developed which is the use of the Total Station. The type is capable of scanning interfaces through a cloud of points based on the control point and back sight (B.S) and processing them by the software used to process the data acquired by the laser scanner. The 3D results of the output model from Total Station are compared with the model’s output from smartphone camera images after processing. In this paper, the interface is scanned, and its details will be mentioned in the case study.
