A Review of Geodetic Datums of Nepal and Transformation Parameters for WGS84 to Geodetic Datum of Nepal

Journal on Geoinformatics, Nepal, 2017
In Nepal there exist different coordinate systems based on different geodetic datum. The existence of these datum and coordinate systems are poorly known. In this literature the geodetic datum that is in existence in one way or other are illustrated and discussed.

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Feasibility of using Group Method of Data Handling (GMDH) approach for horizontal coordinate transformation

Geodesy and Cartography, 2020
Machine learning algorithms have emerged as a new paradigm shift in geoscience computations and applications. The present study aims to assess the suitability of Group Method of Data Handling (GMDH) in coordinate transformation.

Great Slave Lake as a Key Modulator of Dissolved Organic Carbon Fluxes From Boreal Landscapes to the Mackenzie River

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Understanding dissolved organic carbon (DOC) fluxes in boreal freshwater systems is critical for constraining high‐latitude carbon budgets and anticipating climate‐driven changes. Here, we present a retrospective assessment (2000–2024) of DOC fluxes in the Upper Mackenzie River watershed, focusing on Great Slave Lake (GSL), a key hydrological ...

The influence of new vertical datum at existing geodetic plans [PDF]

, 2015
The master's thesis brings attention to the procedures and results of the control of the elevation accuracy in selected geodetic plans. Elevations in the areas of geodetic plans were specified with the method of trigonometric levelling and with reference

Apparent Forest‐Cover Stability Conceals Structural and Functional Landscape Reorganization in a Human‐Modified Atlantic Forest–Cerrado Ecotone

Journal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim To evaluate how long‐term forest turnover reshapes habitat structure and functional connectivity in a human‐modified Atlantic Forest–Cerrado ecotone landscape. Location Sarapuí River Basin, southeastern Brazil. Taxon Native forest vegetation and forest‐dependent taxa of the Atlantic Forest–Cerrado ecotone.

Development of a MATLAB-based graphic user interface (GUI) for 3D datum transformation using Molodensky-Badekas model

Geomatica
Datum transformation is fundamental in geospatial data analysis, enabling the integration of datasets referenced to different geodetic datums. Given the mathematical complexity of datum transformations, this study presents a MATLAB-based graphical user ...

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

On ill-conditioning in 3D Similarity Transformation

International Journal of Environment and Geoinformatics, 2015
3D similarity transformations are often used for datum transformation in Geomatic Engineering. The transformations are routinely performed between the point coordinates evaluated from GNSS (Global Navigation Satellite Systems) observations and the ...

Does Geocentric Sea‐Level Rise in the Maritime Continent Reveal a Tectonic Fingerprint?

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The islands of the Maritime Continent are highly vulnerable to sea‐level rise driven by barystatic, sterodynamic, and vertical land motion (VLM) processes. While tectonics is known to affect relative sea‐level through VLM, its influence on long‐term geocentric sea level (GSL) through crustal deformation and gravity field perturbations remains ...
