Underground Land Administration (ULA) plays a paramount role in recording, registering and managing underground ownership boundaries and rights, restrictions and responsibilities associated with underground assets. 3D digital models provide a great potential to modernise ULA as it is evident in research studies. Several steps, from data acquisition to the use of underground land data have been considered by studies to support 3D ULA. These steps form the ULA data lifecycle. This paper provides an overview of methods, techniques and tools used in different steps of the ULA data lifecycle and identifies research gaps, challenges, and potential opportunities for future studies.

Rockfall event is common on rocky terrain, and it threatens people. Recent advances in remote sensing technologies allow us to model the terrain with high accuracy and resolution. In this study, we show the application of modeling a rockfall site in three-dimensional (3D) using an unmanned aerial vehicle. The acquisition of information about discontinuities in the rock masses using 3D point clouds is vital to characterize rockfall dynamics. We obtained 3D spatial information and point clouds of a rocky slope from acquired images. We extracted 10 discontinuity sets from the 3D model as they have significant effects on the failure mechanism. Details in mapping discontinuities have improved significantly with the help of point clouds. The results are beneficial for modeling the terrain of inaccessible areas with high resolution and obtaining information from those areas. This paper shows how can point cloud analysis be applied to characterize discontinuity sets.
岩崩事件在岩石地形上很常见,它威胁着人们。遥感技术的最新进展使我们能够以高精度和高分辨率对地形进行建模。在这项研究中,我们展示了使用无人机在三维(3D)中对落石现场进行建模的应用。利用三维点云获取岩体中的不连续面信息对于描述岩崩动力学至关重要。我们从获得的图像中获得了岩石边坡的三维空间信息和点云。我们从三维模型中提取了10个不连续集,因为它们对破坏机制有重要影响。在点云的帮助下,映射不连续面的细节得到了显著改善。研究结果有利于对难以到达区域进行高分辨率的地形建模和获取这些区域的信息。本文介绍了如何将点云分析应用于不连续集的表征。

The Oblique Mercator (OM) has been the runt in the family of conformal coordinate projection where its particular attribute of arbitrary orientation has been largely ignored. It is proposed that the Oblique Mercator, as a conformal projection, is well-suited to bridge the gap between a conventional north-oriented projection and the family of engineering grids that are unit-scaled and arbitrarily oriented improve the management of coordinate reference systems (CRS) between GIS and CAD/BIM software that has been, and remains, a significant cause of inefficiency for engineering design and construction, and for plane surveying. Issues relating to the selection of an optimal set of HOM projection parameters are discussed, including a new method to transform an existing engineering grid into an optimised HOM grid.
斜墨卡托(OM)一直是共形坐标投影族中的一个分支,其任意方向的特殊属性在很大程度上被忽视了。有人提出,斜墨卡托作为一种保角投影,非常适合弥合传统的北向投影和单位比例和任意方向的工程网格族之间的差距。它改进了GIS和CAD/BIM软件之间的坐标参考系统(CRS)的管理,这是工程设计和施工以及平面测量效率低下的重要原因。讨论了与HOM投影参数的最佳集合的选择有关的问题,包括将现有工程网格转换为优化HOM网格的新方法。

Through transformation from geocentric to topocentric space rectangular coordinate system and taking advantage of the plain geometrical relationships from the chord between two points on the ellipsoidal surface, the problems of the distances and azimuths on the reference ellipsoid can be converted to several elementary equations and corresponding corrective terms. Based on this, an improved chord method has been proposed in the article. Numeric experiments have validated that the new algorithm can be effective for arbitrary distances. Moreover, the solution can also be operational without singularity in the polar or equatorial regions, in the situations where the difference in longitude is 180°, and in other special cases. And with suitable corrections, the improved method can be prospectively applied to other problems of distances and azimuths with corresponding precision.
通过将地心空间直角坐标系转换为地心空间直角坐标系统,利用椭球面上两点弦的平面几何关系,可以将参考椭球面上的距离和方位问题转化为几个基本方程和相应的修正项。在此基础上,本文提出了一种改进的弦法。数值实验验证了该算法对任意距离都是有效的。此外,在经度差为180°的情况下,以及在其他特殊情况下,该解决方案在极地或赤道地区也可以在没有奇异性的情况下运行。经过适当的修正,改进后的方法可以应用于其他具有相应精度的距离和方位角问题。

Land consolidation is one of the essential tools to increase productivity in agricultural production. The most important, complex, and time-consuming step is land allocation among the land consolidation stages. For these reasons, it is inevitable to use computer technology to optimize this process. This study used reallocation models based on PESA-II and NSGA-II optimization algorithms to solve the reallocation problem. The methods were compared with the optimization algorithms in the literature and the conventional method obtained by the technician. The applied algorithms have achieved successful results by parcel number, average parcel size, and reallocation cost.

Control of geodetic parameters is very important for traffic safety on the railways. Such control must be performed regularly because of the deviation of the track axis due to train traffic. The purpose of the article is the development of a mathematical rationale for the placement of railway benchmarks for the creation of the ‘own’ conditional benchmark network of the railway. These permanent repers are the basic points for both the construction stage and operation stage. The method is described and the curve coordinates from any point of the conditional benchmark network of the railway have been obtained.

This research examined the mapping and analyses of existing polling units in the study area to provide scientific criteria for citing new polling units. The attribute data of the polling units were collected from the Independent National Electoral Commission (INEC), Katsina State, and spatial data was acquired through field observation, for geodatabase creation and query generation. For the suitability mapping, seven parameters criteria were adopted. The generated thematic maps of these criteria were standardised using the fuzzy logic approach. The geodatabase of the existing polling units created showed 281 polling units with their attributes. Also, the suitability map showed regions of suitability and unsuitability. The overlay map showed that 10 polling units were in the region of highly not suitable, 16 not suitable, 26 fairly suitable, then the rest were either highly suitable or suitable. It is recommended that INEC should adopt a scientific method in citing subsequent polling units.

In this contribution, to improve the deformation modelling based on data integration, the LS-VCE algorithm is proposed by obtaining a stochastic model of input multi-sensor data. So, one can achieve the accurate variance-covariance matrix of multi-sensor observations to participate in iterative least-squares. A practical application was made for the settlement observations from geotechnical settlement-meters and geodetic levelling (respectively known as internal and external sensors) to model the surface settlement variation of the Karkhe earth-dam. The determined variance component shows less contribution of the geotechnical settlements in the deformation modelling. An achievement of this paper is that the LS-VCE method improves the integration of the geotechnical with geodetic data by estimating an optimal stochastic model resulting in deformation model optimization. Validation results of estimated surface settlements on the check-points show an RMSE of about 3 cm and a relative-error of about 14%, which indicates the success of the modelling.
为了改进基于数据集成的变形建模,本文通过获取输入多传感器数据的随机模型,提出了LS-VCE算法。因此,可以获得精确的多传感器观测值方差-协方差矩阵,参与迭代最小二乘。利用土工沉降仪和大地水准测量仪(分别称为内测仪和外测仪)的沉降观测,模拟了喀克河土坝的地表沉降变化。确定方差分量对变形模拟的贡献较小。本文的一个成果是,LS-VCE方法通过估计最优随机模型,从而实现变形模型的优化,从而提高了岩土工程与大地测量数据的集成。验证结果表明,各测点地表沉降的均方根误差约为3 cm,相对误差约为14%,表明建模成功。

This paper presents the study of crustal movements and their relation to earthquake activities within Egypt using the GNSS and seismicity measurements. Fourteen campaigns of GNSS measurements have been collected, processed, and adjusted. The collected data of about 50 permanent and campaign GNSS stations, which covered the whole geographic area of Egypt covering about 12 years, were used. The collected data are utilised using differential GPS with surrounded IGS stations by Bernese software V 5.0. The results of the deformation analysis indicate that northern Egypt is deformed more than the southern part.

At present, most of the space-borne atomic clocks used by the major global navigation satellite systems include rubidium atomic clocks, passive hydrogen master (PHM) clocks and cesium atomic clocks. The new independently developed space-borne rubidium atomic clocks and PHM clocks on BeiDou Global Navigation Satellite System (BDS-3) are important hardware improvements. In this paper, performances of new Beidou domestic atomic clocks are evaluated using precise clock offset data from September 2019 to September 2021 and compared with the mainstream space-borne atomic clocks of other satellite navigation systems. The results show that the BDS-3 space-borne PHM clocks have low drift rate and high stability at 86400s interval, which respectively reaches 8.26 × 10−16 and 5.13 × 10−15. These performances are only slightly lower than Galileo PHM clocks. The frequency stability at 86400s interval of BDS-3 rubidium clock is up to 9.03 × 10−15, which is 27.76% higher than GPS rubidium clocks.
目前,全球主要卫星导航系统使用的星载原子钟主要有铷原子钟、被动氢主(PHM)原子钟和铯原子钟。北斗全球导航卫星系统(BDS-3)自主研制的新型星载铷原子钟和PHM钟是重要的硬件改进。本文利用2019年9月至2021年9月的精确时钟偏移数据,对新型北斗国产原子钟的性能进行了评估,并与其他卫星导航系统的主流星载原子钟进行了比较。结果表明,BDS-3星载PHM时钟具有低漂移率和高稳定性,分别达到8.26 × 10−16和5.13 × 10−15。这些性能仅略低于Galileo PHM时钟。北斗三号铷钟在86400s区间的频率稳定度高达9.03 × 10−15,比GPS铷钟高27.76%。
