Abstract:
Abstract. Surveying engineering education includes several outdoor laboratories that complement and enhance theoretical concepts taught in class. In addition, outdoor laboratories develop student skills with instruments and surveying techniques. These laboratories are often affected by weather, leading to cancelled laboratories, which reduce the time students spend with instruments and disrupt/delay the academic plan. Furthermore, terrain characteristics are important in surveying, as each terrain and project introduce unique surveying challenges. However, training often takes places in one location, thus, limiting student comprehension and experience on how to use the same instrument and techniques in different terrain conditions. Virtual reality constantly gains ground in education, as it overcomes restrictions of physical laboratories and enhances student learning. This study discusses the development of a leveling laboratory in immersive and interactive virtual reality, as well as the challenges encountered. We have replicated a part of the Penn State Wilkes-Barre campus, where students conduct many of their physical laboratories, in virtual reality with geometric and photorealistic fidelity using remote sensing and photogrammetric methods. Dense point clouds derived from terrestrial laser scanning and small unmanned aerial surveys are used for terrain and man-made object modeling. In addition, we have developed software that simulates surveying instruments, their properties, and user/student interaction with the instrument (e.g., moving the tripod, leveling the level instrument and leveling rod, etc.). This paper demonstrates that by utilizing cutting-edge remote sensing and virtual reality technologies, we can create realistic laboratories that can supplement physical outdoor laboratories and improve/enhance undergraduate instruction of surveying students.

Abstract:
A digital surveying instrument has a crucial and effective role in civil engineering. These digital surveying instruments have contributed to providing quick and simplified solutions to solve many surveying problems: particularly accuracy, saving time, and effort .Therefore, the main objective of this research is the study of the vibrations effect on digital devices efficiency during the observation process, which occur frequently especially when the devices occupy the bridges during observation or when the occupation of the device is set nearby the railways, as well as in construction sites with heavy equipment movement. Although most digital surveying instruments contain a compensator device, this research find out through the experimental test that the effect of vibration on the accuracy of observation results and the noticed errors may extend to many centimeters. In case of using the digital level devices (SOKKIA SDL-30) under exposure to vibration (up to 20 KHZ/Sec), the average error of elevation was 36.9 mm in 80 m distance and the maximum standard deviation elevation error was 18.26 mm. But in the case of using the reflector-less total station (SOKKIA SET330RK) under exposure to vibration (from 7.5 to 15 KHZ/Sec), the average error of positioning was 79.95 mm in 85 m distance and the maximum standard deviation positioning error was 43.41 mm.

Abstract:
Modern geodetic equipment is developing very rapidly. There is a growing need for modern surveying instruments with modern electronics. These devices differ not only in model number, but also in fundamentally new technological solutions. The latest software is used in the devices themselves and in the processing of geospatial data. It provides more opportunities to automate the process of creating terrain models and the implementation of non-standard geodetic tasks. Therefore, now characteristic of the development of modern geodetic equipment is not to increase the accuracy of measurements, but to optimize the workflow using these devices. This is achieved through the development of hardware and software of these devices. This work is devoted to the comparative analysis of modern electronic geodetic instruments on the basis of specific instruments: total stations and GNSS receivers. The study uses methods: observation - to get acquainted with modern surveying equipment, comparison - to determine the technical features of modern electronic surveying instruments, analysis - to identify trends in modern electronic surveying instruments, sampling - to select instruments that will characterize their categories. A comparative analysis of modern geodetic instruments on the example of total stations Leica TS09 plus 1 "R500, Leica Nova MS60 1" and GNSS receivers GNSS Leica GS08Plus, Leica GS18 I was carried out to determine trends in modern electronic geodetic instruments. Thus, from this analysis follows a certain pattern. It is that there is no race for the accuracy of instruments - modern instruments have a very high accuracy. There is also a new trend in the technological development of geodetic instruments in the direction of increasing functionality and automation.

Abstract:
In the 1830s and 1840s, the Hydrographic Office of the British Admiralty developed and oversaw one of the major state-run surveying projects of the nineteenth century. This involved a range of instruments whose circulation was increasingly regulated. Using extant museum collections and the correspondence of those involved, this article explores how such objects can be used to discuss both bureaucratic organization at a time of expanding government and the complex issues of sociability involved in hydrographic surveying. Surveying officers worked in a context in which the propriety of property on public service was a pervasive question. Instruments might be given as gifts between officers, appropriated as recompense, absorbed as state property, and disputed between friends. The ownership, provision, and treatment of instruments in particular could be used to demonstrate an officer’s peculiar zeal or institutional neglect. To those outside the ship, what was understood as over-instrumentation became amusing spectacle. On board, their use was part of a deeply hierarchical order of work in regions of colonial and mercantile importance. In examining the relationships around these instruments of survey, the paper proposes a richer understanding of the material culture of hydrography in the early nineteenth century.

Abstract An optimized compact-based method is introduced that verifies the distance measuring precision of surveying instruments. The paper describes the improvement of the compact based method not only in establishing a compact facility by using shorter lengths and folded path but also in the assessment process by implementing the official ISO standard for electronic distance measuring equipment (ISO 17123-4). The method produces statistically comparable results to ISO standards and is suited for regular instrument checks in institutions with limited space available.

Abstract This paper is about an unsuccessful scientific instrument. Since its conception, the four theodolites Portuguese naval officer, geographer, and later aviation pioneer Carlos Viegas Gago Coutinho (1869–1959) ordered from the Italian maker and engineer Angelo Salmoiraghi (1848–1939), which were used in surveying missions to the African colonies, caused problems and disagreements. From the user’s perspective, the instruments were poorly manufactured; from the maker’s perspective, the user’s incompetence was to blame. By focusing on a well-documented set of scientific instruments, I will analyse social features concerning scientific practice, material culture, and instrument trade. I will show how the meaning of an adapted and untrustworthy instrument changed during practice; how a crisis between distanced user and maker, concerning design, precision, and error, developed; and how a clash for scientific and professional authority intertwined moral and scientific attributes.

Abstract:
The experimental teaching of surveying is an effective method for students to acquire basic surveying skills and solve practical problems. By contrast, the traditional experimental teaching mode of surveying presents students with insufficient experimental opportunities and difficulties to achieve independent learning and interactive operation due to limitations in the allotted time for experiments, sites, instruments, and external environmental conditions. This study developed a virtual experimental system by combining network virtual reality technology and surveying experiment. The proposed system intends to provide students with additional experimental opportunities to achieve computer desktop-like virtual experimental devices and engineering construction scenes, thereby accomplishing the indoor simulation of field surveying. This virtual surveying experimental system mainly comprised four modules, namely, classroom teaching, classroom practice, teaching practice, and production practice. This system realized equipment, operation, and data virtualizations, as well as various highly realistic measurement experiments, such as topographic surveying, engineering setting out, and road surveying. Application results demonstrated that the proposed system was convenient for the independent study of students, stimulates their enthusiasm for learning, strengthens their operational ability, and achieves good teaching effect. Furthermore, this system provides a novel experimental teaching mode for surveying courses.

Abstract:
With the rapid growth of new surveying and mapping technology and surveying and mapping instruments, engineering surveying has also been developed rapidly. Land survey is a foundation for the country to effectively manage and plan land. When land is used, relevant information can be found in the database established in previous land surveys, so its accurate measurement method is particularly important. On the one hand, there are more and more land surveying work, and the surveying and mapping data of land surveying units are more accurate. On the other hand, with the increasing difficulty of land surveying, surveying units have put forward higher requirements for surveying and mapping technology. Under the background of the continuous growth of China's economy and society, the level of network information technology has improved rapidly, and digital information technology is widely used in land survey, which can improve the efficiency of land survey. This paper analyzes the application of digital mapping technology in land consolidation planning, hoping to provide some reference and suggestions for the smooth growth of land consolidation planning and the improvement of the accuracy of survey results.

Abstract:
Laser trackers (LTs) are dimensional measurement instruments commonly employed in the manufacture and assembly of large structures. Terrestrial laser scanners (TLSs) are a related class of dimensional measurement instruments more commonly employed in surveying, reverse engineering, and forensics. Commercially available LTs typically have measurement ranges of up to 80 m. The measurement ranges of TLSs vary from about 50 m to several hundred meters, with some extending as far as several kilometers. It is difficult, if not impossible, to construct long reference lengths to evaluate the ranging performances of these instruments over that distance. In this context, we explore the use of stitching errors (i.e., stacking errors in adjoining or overlapping short lengths) and stitching lengths (i.e., constructing long reference lengths from multiple positions of a reference instrument by registration) to evaluate these instruments. Through experimental data and a discussion on uncertainty, we show that stitching is indeed a viable option to evaluate the ranging performances of LTs and TLSs.

Abstract:
The purpose of leveling the route is to determine the elevations of all the control points, including the beginning, middle, and end of curves, plus points, and points on transverse profiles. Longitudinal and transverse leveling is carried out after the route has been set out. The results of leveling (elevation measurements) are subsequently used for constructing the longitudinal profile of the route and the transverse profiles.The paper outlines the main principles and methods of leveling, taking leveling readings on rods, referencing the road route to benchmarks, leveling junction and intermediate points, balancing elevation differences, and calculating junction and intermediate points. The paper also describes the control of route leveling and plotting the projected line on the longitudinal profile.Engineering-geodetic surveying, specifically geometric leveling of the route, is an important component of educational geodetic practice. Geodetic practice for students is conducted according to the academic curriculum and serves as a continuation of the learning process in the field. It completes the theoretical course and is conducted according to the academic plan. During practical training, students acquire skills in working with geodetic instruments and processing the results of field measurements, becoming familiar with the main types of engineering-geodetic work during surveys and construction of engineering structures. Students are required to participate in all types of work, conduct the necessary measurements, and process them in the office. Practical training in geodetic practices provides students with hands-on experience in applying theoretical knowledge to real-world scenarios. Through fieldwork, students gain proficiency in using a variety of geodetic instruments such as levels, total stations, and GPS receivers. They learn how to set up and operate these instruments accurately to collect precise measurements of elevation and distance. Furthermore, students learn the importance of teamwork and collaboration during field surveys. Working together with peers, they divide tasks, communicate effectively, and problem-solve on-site challenges that may arise. These collaborative experiences not only enhance their technical skills but also cultivate essential soft skills such as leadership, communication, and adaptability.

Recent developments in localisation systems for autonomous robotic technology have been a driving factor in the deployment of robots in a wide variety of environments. Estimating sensor measurement noise is an essential factor when producing uncertainty models for state-of-the-art robotic positioning systems. In this paper, a surveying grade optical instrument in the form of a Trimble S7 Robotic Total Station is utilised to dynamically characterise the error of positioning sensors of a ground based unmanned robot. The error characteristics are used as inputs into the construction of a Localisation Extended Kalman Filter which fuses Pozyx Ultra-wideband range measurements with odometry to obtain an optimal position estimation, all whilst using the path generated from the remote tracking feature of the Robotic Total Station as a ground truth metric. Experiments show that the proposed method yields an improved positional estimation compared to the Pozyx systems’ native firmware algorithm as well as producing a smoother trajectory.

Examples of measurements using it during sea-ice studies in the Greenland Sea are described. It is shown that the application of the instrument provides a satisfactory basis for precise glacier surveying with limited personnel, cost, and time.

Abstract:
A device was developed, which rotates a marker for the distance measurement in the desired direction, without an operator at the spot. This is also possible with a moving object, on which the marker is set up. The device, together with adequate distance-measuring instruments, yields a precise distance measurement by a single observer at a single station. Examples of measurements using it during sea-ice studies in the Greenland Sea are described. It is shown that the application of the instrument provides a satisfactory basis for precise glacier surveying with limited personnel, cost, and time.

Abstract:
A scale plan is one of the main products in the railway industry. For creating electronic versions of such plans, GIS allowing to combine heterogeneous data obtained by surveying instruments and survey complexes is increasingly being used. GIS has a wide functionality and allows its expanding due to the possibility of developing user software modules, thanks to which it is possible to significantly speed up the process of surveying data processing in order to create scale plans. The results of generating the scale plan according to the survey data obtained with a hardware-software system "Profile-M" and UAV are described. It is discussed that UAV data can reduce the amount of field measurements performed by the hardware-software system, as well as become sources of control measurements for terrestrial surveying.

Abstract:
In surveying engineering we are finding leveling with different instruments in various different field works. So, I am working on different and different instrument finding leveling in surveying. On ours construction industry various instrument are use in leveling likes as Auto level, Dumpy level, Theodolite and total station. In this all instrument we finding leveling in field works like as road, railways, building, sewerage line etc. In this chapter we discuss how to find out leveling and what is easy process in different condition. In this process I am analysis various situations like as project cost, timing. If the project’s cost is high likes as working on national highway or express way and timing of the projects is less in this case I am using total station because of the total station is fastest process of doing working on such types of works. If we are using auto level / dumpy level on that condition we are not comfortable with this instruments because of timing is more required at this projects. But another project likes as a streets making of 100m/200m. In this condition we have not prefer total station because of that condition I am able to working with total station. Total station is required skill labors and the cost of total station is very high as comparisons of auto level /dumpy level and operating system of auto level / dumpy level is to easy as comparison of auto level. If we are working a small projects or low cost project like as 5-10 lakh so, that condition we are not effort total station and skills workers because of the project cost is low as comparison of expanses. Keywords:- Auto level, Dumpy level, Theodolite, Total station.

Abstract:
Similar physical features of two traditional Chinese musical instruments, Guqin and Guzheng, have mistakenly led the general public to discern them as complementary duos. Contrary to this belief, both instruments have different historical backgrounds and purposes. Therefore, this research is conducted to (i) identify the identity of the two instruments and (ii) signify the representations of each instrument. This qualitative research adapted the descriptive comparative research design and used individualizing as an analysis method. In conclusion, despite the similarities in shape and playing techniques, these two instruments depict different messages, leading to other representations and purposes.

Abstract:
In the past decade, drones have become available and affordable for civil applications, including mapping and monitoring the Earth with geophysical sensors. In 2017 and 2019, the feasibility of executing frequency domain electromagnetic (FDEM) surveys using an off-the-shelf drone was investigated at Deltares Institute. This paper reports firstly the preparatory tests executed to determine the optimal instrumental configuration, flight path, data processing and inversion schemes and secondly the three field validation tests executed to demonstrate the feasibility of the drone-borne electromagnetic survey in real-scale applications. At several test sites, the optimal configuration of the drone and electromagnetic instruments, such as the mounting device and distance of the electromagnetic (EM) sensor with respect to the drone, the flight altitude, the coil separation and frequency of the EM source, efficiency and safety, and the assemblage of instrument and drone data were investigated. This has resulted in a robust method to acquire accurate and repeatable in-phase, quadrature and apparent resistivity data, and a workflow for data correction, processing and inversion scheme was developed. During those tests, three EM instruments were tested. The drone-borne electromagnetic (DR-EM) system has the ability and efficacy to fly over inaccessible areas and surface water. Compared to helicopter-borne electromagnetic surveys, the spatial resolution is much higher, which allows very detailed 3D mapping of subsurface targets, and the survey costs are relatively low. Repeated drone-borne electromagnetic (DR-EM) surveys allow low-cost monitoring of local changes in water saturation and salinity.

Abstract:
The uncertainty evaluation of survey measurements is a daily and essential task in any surveying work. The result of a measurement is, in fact, only complete when accompanied by a statement of its uncertainty. Miscentring, or centring error, is one of the sources of uncertainty in every basic survey measurement which may have a great effect on horizontal angle measurement for short distances. In the literature, different terms and values are considered to refer to this source of uncertainty. Standard ISO 17123 provides different procedures for assessing the measurement uncertainty of geodetic and surveying instruments, with the aim of checking their suitability for the intending and immediate task in field conditions. ISO 17123 is aware of the importance of uncertainty in the instrument centring, but it does not propose any standardised procedure for its assessment. In this study, we propose such a procedure following a Type A evaluation (through the statistical analysis of series of observations), avoiding using values from Type B evaluations (from manufacturer’s specifications, handbooks, personal experiences, etc.) that could be unsuitable for the conditions of the task. Uncertainty can be individualised for a particular instrument (which includes the plummet type), ground mark, operator, and other factors on which the results could be dependent. The testing methodology includes a configuration of the test field, measurements, and calculation, following the structure of each part of the standard ISO 17123. An experimental application is included with two different total stations, which also includes a statistical analysis of the results.

Abstract:
This paper introduces the usage and reliability of Motorized GPSSIT technique which is a novel approach for surveying. It reviews the advantages of Motorized GPSSIT concept and also considers to provide GNSS accuracy in the process of surveying especially for the cases which cannot be surveyed directly by the satellite navigation systems (GPS-GNSS), such as closely packed residential areas, tall buildings, trees, etc., and also places which GNSS receivers cannot be work efficiently due to signal interferences. In this technique, all the survey instruments are installed on a bed of a pick-up truck whereas in present techniques they are installed on the ground, therefore it is called Motorized GPSSIT. Study area was chosen within the housing area of our campus. In this area, classical surveying, GPSSIT and Motorized GPSSIT were performed to collect data for comparison and for the analysis of this technique's usability and reliability. Stop and Go and RTK surveying techniques were performed with GPSSIT and Motorized GPSSIT concepts. It is shown that the Motorized GPSSIT technique is applicable as other present techniques in terms of accuracy and reliability.

Abstract:
Abstract For the implementation of environmental technical projects, such as the urban forest management, a key element is the topographical and cartographic mapping of the area. Topographical instruments are based on digital, aerial or satellite information’s that can be used for producing topographical maps. This research aims to highlight that UAVs in combination with low-cost survey methods, produce topographical mapping with accepted accuracy for the implementation of environmental projects, how we can survey a road network in order to produce digital topographic maps and also how the implementation of four different ways of measuring can help us to accomplish it. The methods for executing topographic projects differ in quality, accuracy, time and cost. The results of surveying with a total station, a binary satellite positioning system, a handheld satellite positioning system and an unmanned aerial system were compared based on the accuracy of the results. Estimation of measurement error combined by the time required and the cost of each instrument and associated software for data processing were estimated. The results obtained prove that low-cost methods give sufficient and acceptable accuracy; especially the Unmanned Aerial Systems, are capable of being used for the design and implementation of forest urbanization studies.

Abstract:
Increasing the accuracy of geodetic measurement tools and methods used in land surveying, topographic mapping, and other works is one of the requirements of the current era. In this case, it is important to develop measures aimed at increasing the speed of geodetic surveying, increasing the accuracy of measuring land areas, and reducing labour productivity, time, and human resource costs. The use of electronic geodetic measuring devices in implementing these works is very convenient for implementing the above requirements. The difference between the current electronic geodetic measuring instruments and the previous ones is that they are designed to measure the angle, distance, and height of points simultaneously.

Abstract:
Objective: The study aims to investigate the use of dental instruments without sterilization and to evaluate the status of infection control in domestic dental clinics. Methods: A total of 357 participants were enrolled, from April to May 2020, after surveying 20 dental institutions. We assessed all the instruments used during treatment, particularly those which were reused without sterilization. In cases where specific instruments were not listed, respondents marked ‘etc.’ and provided details. The frequency of infection control practices, including hand washing, wearing masks and gloves, surface disinfection, and instrument sterilization, was analyzed. Results: Reusable instruments without sterilization included the 3-way syringe, scaler, handpiece, inject syringe, bur, paper holder, and other endodontic tools. Notably, the 3-way syringe, injection syringe, handpiece, and paper holder were reused in over 50% of cases. Gloves and masks were worn 95–100% of the times during oral examinations, while handwashing rates were 25–30% pre-treatment and over 80% post-treatment. Handpieces were used in endodontic treatments and extractions, being sterilized 50–60% of the times. Conclusions: This study revealed insufficient infection control measures in dental institutions. Addressing this issue requires ongoing education, proper training of dental professionals, and essential financial support for effective measures.

Abstract:
In spite of the tremendous success in artificial intelligence technology and a high level of automation in geospatial data obtaining processes, there is still a need for topographical field data collection by professional surveyors. Understanding terrain topology and topography is a cognitive skill set that has to be demonstrated by geospatial Subject Matter Experts (SME) for the productive work in the topographic surveying field. For training of the mentioned above skillset, one has to be exposed to the theory and must also practice with surveying instruments in field conditions. The challenge of any surveying/geospatial engineering workforce training is to expose students to field conditions which might be limited due to equipment expenses and meteorological conditions that prevent good data collection. To meet this challenge, the Integrated Geospatial Technology research group is working on a geospatial virtual reality (VR) project which encompasses the following components: (a) immersive visualization of terrain; (b) virtual total station instrument; (c) virtual surveyor with reflector installed on the virtual rod. The application scenario of the technology we are working with has the following stages: (1) student is installing total station on the optimal location; (2) students move virtual surveyor on the sampling points they consider to be important (3) contours are generated and displayed in 3D being superimposed on 3D terrain; (4) accuracy of terrain modeling is observable and measurable by comparing the sampling model with initial one.

Music students are more likely to get Musculoskeletal Disorders (MSDs), fatigue, and pain. However, limited studies compared MSDs, pain and fatigue between different types of musical instrument players. This study compared MSDs, pain, and fatigue among music students who play wind and string instruments. A cross-sectional study was conducted with a group of music students in one of the universities in Malaysia. No statistical differences in pain and fatigue were found, but more wind players experience MSD at the wrist and hand than string players. Therefore, students who play string instruments should be more watchful with MSD symptoms. Keywords: Musical instruments, pain, fatigue, musculoskeletal disorder eISSN: 2398-4287 © 2022. The Authors.

Abstract. The main goal of this ongoing research is the evaluation of the iPad Pro built-in LiDAR sensor for large scale 3D rapid mapping. Different aspects have been considered from the architectural surveying perspective and several analyses were carried out focusing on the acquisition phase and the definition of best practices for data collection, the quantitative analysis on the acquired data and their 3D positional accuracy assessment, and the qualitative analysis of the achievable metric products. Despite this paper is a preliminary analysis and deeper studies in various application environment are necessary, the availability of a LiDAR sensor embedded in a tablet or mobile phone, appears promising for rapid surveying purposes. According to test outcomes, the sensor is able to rapidly acquire reliable 3D point clouds suitable for 1:200 architectural rapid mapping; the iPad Pro could represent an interesting novelty also thanks to its price (compared to standard surveying instruments), portability and limited time required both for data acquisition and processing.
