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:
AbstractModern scanners can perform terrestrial topographic survey with resolution of 1 cm and accuracy of 2 mm in just a few minute‘s time, from the distance of up to 100 meters. However, for surface topographical surveying of large territories or complex industrial objects, it is necessary to conduct geodetic traverses and perform their binding to the points of the geodesic basis. One method of coordinate transferring during surveying is by using the method of inverse linear-angular intersection, which involves the measuring of the respective sides S1, S2 and the β angle between them. This method is more precise than the classical one, which usually contains centring and reduction errors. The linear-angular intersection method can also be used for many applications in engineering geodesy, for laying geodetic traverses, and for binding to the wall based points of ground-surveying.

Abstract:
A topographical map is a map that contains information about the elevation of the land surface in a place to the mean sea level (Mean Sea Level), which is depicted by contour lines. Information from the coordinates and elevation of detailed land points as a result of land surveying can be used to create a three-dimensional model of the land surface on the map using the Quantum Geographic Information System (QGIS) software application. With a three-dimensional (3D) model, the objects on the map are seen more alive as they actually are in the field, so that analyzing a topographic map can be done more easily. To support these activities, three-dimensional (3D) land contour modeling was carried out with QGIS software on topographical mapping in Buwit Village, Kediri District, Tabanan Regency, Bali.

Abstract:
Serbian military topographic and cartographic activity has existed for almost 150 years. During that time, a relatively small country like Serbia faced difficult temptations but successfully produced topographic maps. During this period, Serbia was affected by numerous wars and other trials. First, there was a war for liberation with the Turkish Empire, then came the Balkan Wars, the First and Second World Wars and the transformation of Yugoslavia from a kingdom into a socialist state, as well as the final disintegration of Yugoslavia. During all that time, the Serbian army managed to create maps that were a necessary tool used by many civilian institutions. Serbian military topography developed solutions related to geodetic surveying, and cartography provided and developed many maps of different scales with appropriate cartographic keys. Although it often faced difficult situations, the Military Geographical Institute - MGI managed to recover, train new personnel, and continue with topographic surveying, map making, aerial photogrammetry, application of satellite images and implementation of digital technology. In this paper, we provide primary data on the development of military cartographic and topographic activity through a presentation of results and activities from establishing the Military Geographical Institute to the present day. The topographic activity, in addition to topography, includes trigonometric and levelling surveying.

Abstract:
This article examines a particular problem in the early history of photographic land surveying: the unwavering desire to use photography to capture accurate topographical information for map-making, even in light of practical difficulties. It considers how both the practical survey work and the status of photography changed when, instead of the landscape itself, photographs were measured. Photography’s promise to simplify strenuous fieldwork was almost as old as photography itself—but in practice, it took decades of experimenting until the process was feasible.

Abstract:
Dwerige weir is a small hydraulic structure was constructed for reducing the flooding impact, irrigation regulation and environmental purposes. Also, the project was considered as a pilot water harvesting project in the eastern part of Missan Province. In this study, the problem of siltation in the weir reservoir was studied depending on the topographic surveying data of the reservoir, before it is was filled with water, and the final silt elevation taken directly during the reservoir drying period. The study uses the topographical and geotechnical approach to calculate the silt volume and the economic estimation of the economic loss of the project. A comparison between the designed and real project lives was made and the results are discussed in detail in order to avoid this problem in the future of the weirs and dams in the study area.

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.

Abstract:
Currently, the existing approaches to geodetic support for the design, survey, construction and reconstruction of buildings and structures do not fully meet the needs of the construction industry. Digital large scale topographic plans do not fully reflect the situation on the construction site. In this regard, to supplement digital engineering and topographic plans with information obtained using the survey materials of unmanned aircraft systems (UAS) is proposed. The article discusses the possibilities of obtaining and processing the materials of surveying with UAS at low altitudes, using the example of the construction of a new metro station in Novosibirsk. The DJI Phantom 4 PRO quadrocopter was used as a UAS. The accuracy of the obtained orthophotoplan is sufficiently suitable as explanatory information for the digital engineering and topographic plan of the object under study.

Full text
Abstract:
A method is presented for the determination of interface topography of multi-layered crustal models from gravity or magnetic data. The technique is developed within the framework of discrete linear inverse theory and exploits the quasi-linearity of the problem to derive a simple cost-effective algorithm suitable for use on large gridded data sets.
Variation of auxiliary parameters allows a suite of acceptable models to be produced rapidly and appraised in the light of available geological and geophysical evidence. When independent knowledge concerning the behaviour of specified interfaces is available, the incorporation of such data in the form of linear equality constraints is outlined.
The proposed method is applied to Curie isotherm and Moho mapping in the Abitibi greenstone belt.

Abstract:
Digital heterodyne methods are employed in conjunction with periodic fringe projection to produce a fast automated surface relief measurement technique. A method of sampling the image with a solid state detector array which produces a moire fringe image free of the noise terms normally present with moire techniques is presented along with an extension to Whittaker-Shannon sampling theory to cover the moire aliasing phenomena. The limitations imposed on the surface slopes by the requirement that the properly moire sampled image spectra must be confined to a moire interval are given. Moire sampling allows an optical processing step (removal of the reference surface tilt), while classical nonaliased sampling produces the same information with respect to a tilted surface. General additive noise is analyzed as regards both integrating bucket and phase stepping algorithms and yields a signal to noise ratio dependent error with twice the frequency of the fringes for some algorithms. A phase averaging technique which eliminates these oscillatory errors as well as those caused by reference phase shift errors in all the algorithms is demonstrated. Both parallel and divergent geometries are discussed. The feasibility is experimentally demonstrated with results for the parallel case based on a system composed of commercially obtainable components.

Abstract:
Fine-scale resolution digital elevation models (DEMs) created from data collected using high precision instruments have become ubiquitous in fluvial geomorphology. They permit a diverse range of spatially explicit analyses including hydraulic modeling, habitat modeling and geomorphic change detection. Yet, the intercomparison of survey technologies across a diverse range of wadeable stream habitats has not yet been examined. Additionally, we lack an understanding regarding the precision of DEMs derived from ground-based surveys conducted by different, and inherently subjective, observers. This thesis addresses current knowledge gaps with the objectives i) to intercompare survey techniques for characterizing instream topography, and ii) to characterize observer variability in instream topographic surveys. To address objective i, we used total station (TS), real-time kinematic (rtk) GPS, terrestrial laser scanner (TLS), and infrared airborne laser scanning (ALS) topographic data from six sites of varying complexity in the Lemhi River Basin, Idaho. The accuracy of derived bare earth DEMs was evaluated relative to higher precision TS point data. Significant DEM discrepancies between pairwise techniques were calculated using propagated DEM errors thresholded at a 95% confidence interval. Mean discrepancies between TS and rtkGPS DEMs were relatively low (≤ 0.05 m), yet TS data collection time was up to 2.4 times longer than rtkGPS. ALS DEMs had lower accuracy than TS or rtkGPS DEMs, but ALS aerial coverage and floodplain topographic representation was superior to all other techniques. The TLS bare earth DEM accuracy and precision were lower than other techniques as a result of vegetation returns misinterpreted as ground returns. To address objective ii, we used a case study where seven field crews surveyed the same six sites to quantify the magnitude and effect of observer variability on DEMs interpolated from the survey data. We modeled two geomorphic change scenarios and calculated net erosion and deposition volumes at a 95% confidence interval. We observed several large magnitude elevation discrepancies across crews, however many of these i) tended to be highly localized, ii) were due to systematic errors, iii) did not significantly affect DEM-derived metric precision, and iv) can be corrected post-hoc.

In this study, the state-of-the-art of satellite positioning technology, such as GNSS (Global Navigation Satellite System) and e-GNSS (Electroncial-Global Navigation Satellite System), are used in Densified Cadastral Control Resurveying. Two re-survey areas, Lujhu Township and Pingzhen City, in Taoyuan County, are selected as the study area, and the result will be compared with the declared TWD97 coordinates of topographical control points in 2013. The results are summarized as follows: (1) With Rapid Static GNSS, baseline observations were increased and the success rate of solving integer ambiguities are improved. So the visible satellites were increased by 66-100% with GPS system only. The success rate of solving baselines will reach 94~95% in 5, 10 and 15 minutes. Furthermore, the success rate of solving baselines reach 95~97% in 20 minutes. We compare the calculated coordinates with the known coordinates, and more than 91% of the discrepancies were within 2 cm. (2) With e-GNSS, the success rate was increased by 85.7-95%. The compare between the calculated and the known coordinates, and more than 83.4% of the discrepancies are under 2 cm. It shows that all calculated results meet the accuracy specifications by MOI(Ministry of the Interior). This study demonstrates that both rapid static GNSS and e-GNSS can significantly reduce the observation time, achieve high precision, high quality in surveying and mapping. From this work, It can be concluded that rapid static GNSS is suitable in common region for its unrestricted property by Internet communication, while e-GNSS is appropriately applied in area for a better internet communication.

AbstractThe paper presents a case study on the application of Geomatics to terrain’s deformation monitoring. Within the EU H2020 LiquefACT project, the Laboratory of Geomatics of the University of Pavia (Italy) was appointed to quantify the subsidence suffered by the terrain due to some trials conducted in the test site of Pieve di Cento, Northern Italy. Geomatics has long been used for deformation monitoring, but present paper deals with two peculiar elements: the constraints given by the test field, its layout, the allowed and forbidden actions, that forced the surveyors to elaborate an unconventional surveying design, and the use of a state-of-the-art instrument, the Trimble SX10. It mainly is a high-level topographic total station; being robotized, it has interesting laser scanning capabilities. In the paper, the survey design will be illustrated and discussed, and a selection of the obtained results will be presented. They highlight how much geomatics can be flexible and adaptable and, at the same time, precise and accurate.

Abstract After surveying the existing historiography on service, this chapter proposes a new approach to studying female servants in early modern England. Offering a corrective to the prescriptive codes of behaviour disseminated in legal treatises and didactic literature, this book systematically unpicks evidence of the lives of over 1000 female servants recorded in church court depositions and recasts the household-centred, patriarchal context in which they have previously been studied. The chapter introduces central themes of the book: age and social structure of service, regulation and law, agency and freedom, work, and community. This chapter introduces readers to the church courts and the depositions upon which this study rests. Drawn from a variety of regions across the south and south-west of England, the women within the book lived in both urban and rural settlements that offer different economic, topographical, and social contexts for their study.

Abstract:
High resolution topographic maps are critical for the development of rigorous and quantitative numerical simulation landscape models. These models can inform targeted land management actions that maintain biodiversity and ecological functions. Mapping functional vegetation communities to obtain accurate distribution and population estimates is an important element of landscape models and is a challenging task which requires a considerable investment in time and resources. A recent development in surveying technologies, Unmanned Aerial Vehicles (UAV’s), also known as drones, has enabled high resolution and high accuracy ground-based data to be gathered quickly and easily on-site. The application of UAV’s represents a new opportunity to survey relatively large areas in significantly less time compared to other on-site surveying methods, including GPS, robotic total stations and terrestrial laser scanners. The objective of this research is to use UAV technology to create topographical and vegetation mapping of coastal dune complexes with particular reference to the Brittas-Buckroney dune complex in Co. Wicklow. As the area of study site was about 60 hectares, it was divided into three sections, North, Centre and South. This paper presents the five steps to achieve the objective, setting ground control points, making an autonomous flight plan, flying the UAV for data collection, data processing and result analysis via ArcGIS. The final result, processed by specific software PIX4D, was a topographical map of the study site in the Irish Transverse Mercator coordinate system, with a resolution of 0.125 m and Root-Mean-Square (RMS) error 0.050 m. In conclusion, UAV technology provides new possibilities for mapping as it maximizes improvement of the data quality while reducing the investment in time and labour.

Abstract:
The article examines the critical role of the surveying engineering industry in Ukraine, a sector pivotal in upholding land and real estate rights, facilitating real estate markets, spatial planning, public administration, environmental protection, and man-made safety. The outbreak of war poses significant challenges to this industry, primarily driven by economic growth, as armed conflicts result in a marked decrease in the country’s economic activities. Understanding these challenges is essential for maintaining the continuity of surveying services during such conflicts. The primary objective of the article is to evaluate the detrimental impact of the Russian Federation’s armed aggression on Ukraine’s surveying engineering market and propose potential recovery pathways. The methodology employed involves analyzing public data on cadastral administrative services and leveraging business analytics tools for public procurement, specifically focusing on the procurement of topographic survey services between 2022 and 2023. This approach allows for a first-of-its-kind quantitative assessment of the war repercussions on Ukraine’s topographic-geodetic and land surveying sectors. The article meticulously analyzes the main challenges faced by these industries and suggests directions for post-war recovery. By thoroughly understanding the impact of war on the land surveying sector, the article aims to equip policymakers, industry professionals, and stakeholders with the knowledge to make informed decisions. Such insight is crucial for developing effective strategies to navigate and mitigate the challenges posed by the conflict, thereby ensuring the resilience and continuity of vital surveying engineering services in Ukraine.

Abstract:
Finite and decreasing landfill space on Army installations is a significant concern. Efficient waste management is essential for achieving resiliency and extending the lifespan of remaining landfills. The purpose of this demonstration was to conduct independent performance tests of small unmanned aircraft systems (sUAS) and their utility for providing landfill assessments in remote areas where physical presence is either dangerous or inefficient. An active, near capacity construction and demolition (C&D) landfill at Fort Gordon, Georgia, was identified for the demonstration. The flights, data requirements, and outputs generated by the sUAS flyovers were analyzed for efficacy in detecting cell capacity and subsidence. Each flight took 1–2 hours for mobilization, ground marker placement, flight, and postflight analysis. Volumetric and topographic surveys were analyzed in less time than is typical for traditional surveying methods. After initial setup of ground markers and rectification, sUAS flights save a significant amount of time. However, skilled individuals are required for flights and for processing and maintaining data. The technology is widely relevant to the Army, is commercially available, and offers an average of 30% cost savings in terms of manpower, repeatability, and equipment. The use of sUAS technology is recommended for monitoring and surveying Army landfills.

L51574 Non-Conventional Means for Monitoring Pipelines in Areas of Soil Subsidence or Soil Movement. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), June 1988. http://dx.doi.org/10.55274/r0010329.

Abstract:
Examines non-conventional techniques for monitoring curvatures, displacement, or strains in buried pipelines. Internal devices, external devices, and fiber optic techniques were examined. Feasibility of each system is discussed and the most promising are identified. Two companion studies 'Guidelines Pipeline Strain Monitoring by Conventional Means' (Reference 1) and 'A Proposed Model for the Intervention Decision Making Process in Pipeline Movement Situations' (Reference 2) have already been completed, and an effort to determine appropriate failure criteria for pipelines in areas of soil instability is currently underway. The objective of this study is to describe methods of pipeline monitoring which are, for the most part, still in the conceptual and/or development phases. It is very likely that the techniques described herein will require extensive validation efforts and significant financial support before they will become reliable tools for routine use Improved pipeline strain monitoring techniques are needed because the conventional techniques (strain gages, inclinometers, and topographical surveying) meet all of the industry's needs. The conventional techniques are expensive, labor intensive, and require access to the pipeline for installation . As such they are limited in use to localized trouble spots that are known to be a problem. None of these techniques could be practically applied to a whole pipeline for any-time monitoring. Techniques that will better satisfy the industry's needs must be adequately sensitive, applicable to the whole pipeline, available at all times (or at least at reasonably frequent intervals), and capable of use without the need to excavate the pipeline or to interfere with its operation.Several non-conventional techniques for monitoring curvatures, displacements, or strains in buried pipelines that may meet these requirements are discussed herein. These fall into three generic classes: internal devices (instrumented pigs), external devices (involving moving a detecting device over the pipeline right-of-way), fiber-optic cables attached to the pipeline over its entire length.
