Development of a computer software for the monitoring of subsidence [PDF]

, 2004
A computer software has been developed at the Faculty of Geoinformation Science and Engineering, UTM for the purpose of detecting subsidence of ground surface or manmade structure by using Visual Basic 6.0 and FORTRAN computer languages.

Reconstruction of Core‐Surface Flows During the Last 3,300 Years

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Understanding the Earth's magnetic field evolution requires examining the fluid flow at the core‐mantle boundary that drives the changes over different timescales. The inversion process to derive core‐surface flow velocities from secular variation data encounters non‐uniqueness issues, necessitating a priori assumptions that yield different ...

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.

Uplift and subsidence associated with the great Aceh-Andaman earthquake of 2004 [PDF]

, 2006
Rupture of the Sunda megathrust on 26 December 2004 produced broad regions of uplift and subsidence. We define the pivot line separating these regions as a first step in defining the lateral extent and the downdip limit of rupture during that great M_w ≈

Brown Bear (Ursus arctos) Field Sign Monitoring for 40 Years (1976–2015) in Northern Hokkaido, Japan, During a Wildlife Management Policy Shift

Ecological Research, Volume 41, Issue 2, March 2026.
Long‐term (1976–2015) field sign monitoring of brown bears in northern Hokkaido, Japan, yielded 2421 records (feeding signs, tracks, scats) along 9890 km of survey routes. The digitized spatiotemporal dataset provides insights into population dynamics, habitat use, and feeding behavior across a major wildlife management policy shift.

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 ...

Understanding Compound Pluvial–Fluvial Flood Hazards Under Climate Change: A Case Study of the Lower Tone River Basin, Japan

Hydrological Processes, Volume 40, Issue 2, February 2026.
A hindcast of Typhoon Hagibis inundation in the Lower Tone River Basin demonstrates reasonable consistency with observations. Scenario‐based simulations were performed to quantify flood hazards in this coastal watershed until the end of the twenty‐first century. Agricultural lands, most of which were reclaimed from lakebeds, face a greater flood hazard

Tracking Baseflow Supply Dynamics Using SWOT Data From Small Groundwater‐Dominated Lakes

Hydrological Processes, Volume 40, Issue 2, February 2026.
Satellite‐based measurements of groundwater flow‐through kettle lakes efficiently track dynamic groundwater storage at local to regional scales (modified from USGS Scientific Investigations Report 2011–5137). ABSTRACT In situ surface‐water monitoring strategies are biased towards larger perennial streams and lakes and are generally not designed to ...

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 ...

Integrating Urban Expansion and Flood Risk: A Spatial Assessment of Impervious Surface Growth and Floodplain Exposure in Mecklenburg County (2011–2021)

World Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Urban expansion significantly impacts flood risk, particularly in rapidly growing areas where impervious surfaces exacerbate surface runoff. This study examines spatial patterns of urban growth and their effects on flood exposure in Mecklenburg County, North Carolina, from 2011 to 2021.
