AbstractThe study initiated an evaluation of the GNSS continuously operating reference stations (CORS) performance for Network-based Real-Time Kinematic (NRTK) positioning in Thailand, using the deemed rover analysis approach. Fifty CORS were selected as rovers with varying network geometries. Results indicated the highest performance, 79.9% of fixed solutions, for an average triangle side length of 54 km, while the lowest performance, 29.9%, was observed for a 93 km length with accuracies at a decimetre level. These initial explorations suggest that reducing side lengths enhances fixed solution efficiency and positioning accuracy at rovers. Occasional metre-level errors occurred, potentially linked to Internet instability.Keywords: Deemed rover analysisVRSNRTKGNSSRTKLIB AcknowledgmentsThe authors would like to express their gratitude to the Royal Thai Survey Department (RTSD) for providing all the necessary data and equipment support.

AbstractResearchers and manufacturers use the Precise Point Positioning (PPP) technique. After the phase biases of the satellites are resolved from GNSS networks, they are broadcast to users as Fractional Cycle Bias (FCB). In this study, FCB products provided by WUHAN, CODE, CNES and JAXA services were downloaded and PPP Ambiguity Resolution solutions were realised by Net_Diff software. For ten days in 2022, 24-hour observations were collected from 40 International GNSS Service stations. As a result, it has been observed that WUHAN and CODE services provided the ±1 cm or ±5 cm accuracy level by converging in short-term observations.Keywords: PPP-ARConvergence timeFractional cycle biasGNSSInteger ambiguity AcknowledgementsWe would like to thank the International GNSS Service (IGS) for data and reference product support, and Wuhan University for Net-Diff software.

AbstractLand price maps help the government and stakeholders to recognize fluctuations in land values in the economy. This paper aims to examine the trends of land lease prices from spatio-temporal perspectives for development. The study employed a mixed research approach. The result indicated that the lease price of residential land has been increasing rapidly in the past decade. Inefficiency in the land administration system, high speculation, and low provision of land for auction are the main drivers for the increment. The researchers thus suggest that the government rethink the tenure system, impose the maximum number and size of land parcels, and introduce the capital gain tax.Keywords: Land priceleaseland value mapspatio-temporalEthiopia AcknowledgmentsThe authors would like to thank all participants of the study for their time and patience in participating in the survey which forms the basis for this research.

AbstractIn the paper, the differences between position components obtained using the precise point positioning (PPP) technique with individual and type mean PCC models were investigated. Daily GNSS observations from ten selected European Permanent Network (EPN) stations were used in the study. Eight different combinations of GPS, Galileo, BeiDou and GLONASS systems observations were proposed for analyses. The observation processing was done using the open-source software package GAMP. The results show that differences in the calibration models propagate to the position domain. Position offsets, resulting from the use of individual calibrations instead of the type mean, reach up to 10 mm in the vertical component while are generally keeping below 2 mm in the horizontal ones. The analysis also shows that adapting GPS PCCs to other GNSS (e.g. Galileo or BeiDou) signals does not significantly increase achieved position component differences.Keywords: multi-GNSSEPNantenna phase center correctionsposition components time seriesPPP AcknowledgmentThe author is grateful for GNSS data provided by the International GNSS Service, EUREF Permanent Network, and Zhou et al.

摘要本文研究了精确点定位(PPP)技术在个体和类型平均PCC模型下得到的位置分量的差异。研究中使用了10个选定的欧洲永久网络(EPN)站的每日GNSS观测数据。提出了GPS、伽利略、北斗和GLONASS系统观测的8种不同组合进行分析。使用开源软件包GAMP进行观测处理。结果表明，标定模型的差异会传播到位置域。由于使用个别校准而非型号平均值，垂直组件的位置偏移可达10毫米，而水平组件的位置偏移通常保持在2毫米以下。分析还表明，将GPS PCCs与其他GNSS(例如伽利略或北斗)信号相适应不会显著增加所获得的位置分量差异。关键字:多gnssep纳米天线相位中心校正位置分量时间序列PPP致谢感谢国际GNSS服务、EUREF永久网络和Zhou等人(Citation2018)提供的GNSS数据免费共享GAMP软件。披露声明作者未报告潜在的利益冲突。karol Dawidowicz karol Dawidowicz于2001年在奥尔什丁的瓦姆尼亚和马祖里大学获得卫星大地测量学博士学位。主要研究方向为GNSS调平、GNSS天线相位中心变化建模和精密点定位。他是全球导航卫星系统数据处理高级方法组的成员。Mieczysław BakułaMieczysław Bakuła于1999年获得卫星大地测量学博士学位。他的研究主要集中在全球导航卫星系统的定位及其在测量和导航中的应用。他是精确和快速的歧义解决/重新初始化方法(PREFMAR)的作者。

AbstractThe goal of the study is to determine how land users affect the land certification process when compared with other factors. We investigated government officials who carry out land certification procedures through a two-step survey to identify hypothetical factors that influence land certification. A multivariable regression model of hypothetical factors affecting land certification was tested by evaluation criteria. There are 26 factors belonging to 7 groups affecting land use right certificate issuance. Their impact rates ranged from 3.43% to 25.95%. Land users impact the issuance of land certificates with an impact rate of 20.82%. This puts them in the second most influential group after the group of policy and legal factors. For the land certificate to be granted smoothly and on schedule, it is necessary to pay attention to solving issues related to land users, legal policies, and other factors that have a smaller impact rate.Keywords: Factors affectingImpact ratesLand certificationLand usersThanh Hoa City Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsNguyen Dinh TrungNguyen Dinh Trung obtained his Ph.D. in Land Management at Vietnam National University of Agriculture (VNUA) in 2023.

AbstractIn this study, the coastal changes in Hersek Lagoon, have occurred in the 5 years (2015 to 2020) were examined. With the Modified Normalised Difference Water Index (MNDWI), the water areas in the lagoon were determined by object-based classification. When the changes are examined on a regional basis, it is seen that there are erosion and accretion areas were observed. Pearson's r value was examined between End Point Rate (EPR) and Linear Regression Rate (LRR) and a high correlation such as r = 0.921 was obtained. The maximum coastal change was observed as 18.74 m/year with EPR and 18.62 m/year with LRR.Keywords: Shoreline changeDigital shoreline analysis system (DSAS)Object-based classificationExtractionHersek lagoonGeospatial analysis AcknowledgementsThe authors thank to the ESA for free satellite data and thank to the NASA for DSAS software.Data availability statementSince the data used is free data that anyone access from ESA, we would not share the data in anywhere.

This study examined the existing legal framework for mobilizing, distributing, and utilizing customary land revenue in Ghana. It combined a review of the regulatory framework on land revenue management and face-to-face interviews with Officers of the Administrator of Stool Lands with the view to identifying the gaps inherent in these regulations. The study found that the lack of legislative clarity on the mobilization and application of stool land revenue has been responsible for the misappropriation of funds by beneficiaries. Legislative reform is recommended to remedy the inherent gaps in the land revenue management regime in Ghana.
