Coordinated cadastral system for Peninsular Malaysia : from concept to reality [PDF]

, 2005
The main objectives of conducting cadastral surveys that had been promulgated in the early days of its practice have since been continually adhered to and later came to be adopted as amongst the principal functions of DSMM. They were stated in the Survey

Precipitation Over Complex Mountain Terrain in a Convection‐Permitting Regional Climate Model

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract Orographic precipitation is a critical freshwater source and major flooding hazard, but its distribution and behavior over complex terrain are often uncertain due to sparse observations. We examine precipitation and its drivers in one of the wettest regions in the world, the Southern Alps of New Zealand (NZ), using the first multi‐decadal ...

Converting NAD83 GPS heights into NAVD88 elevations with LVGEOID, a hybrid geoid height model for the Long Valley volcanic region, California [PDF]

, 2008
A GPS survey of leveling benchmarks done in Long Valley Caldera in 1999 showed that the application of the National Geodetic Survey (NGS) geoid model GEOID99 to tie GPS heights to historical leveling measurements would significantly underestimate the

The First Firn Core From the Cordillera Darwin Icefield: Implications for Future Ice Core Research

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The Southern Hemisphere westerly winds (SHWWs) (45–65°S) are important regulators of the Southern Hemisphere climate. The scarcity of observational records at the core of the wind belt hinders our understanding of the environmental impact and long‐term variability of the westerly winds.

Transformation of GPS measurements in the Košice hollow into the national geodetic grid [PDF]

Acta Montanistica Slovaca, 1999
The paper deals with transformation procedures observed GPS (Global Positioning System) data from the World Geodetic System WGS-84 into the national grid datum S-JTSK and Bpv. GPS measurements are realized on the geodetic network in the Košice-hollow for

Estimation of Geopotential Value W₀ for the Geoid and Local Vertical Datum Parameters

Remote Sensing, 2023
Unification of the global vertical datum has been a key problem to be solved for geodesy over a long period, and the main challenge for unifying the global vertical datum system is to determine the geopotential value W0 of the geoid and to calculate the ...

Actionable Science for Small Island Communities: Wind Velocity and Sea‐Level Rise Enhance Tidal Flooding on Little Cumberland Island, Georgia

Community Science, Volume 4, Issue 2, June 2025.
Abstract Small island communities are among the first and hardest impacted by sea‐level rise, though climate initiatives often focus on more heavily populated and economically productive coastal cities. Furthermore, most climate‐impact studies focus on regional scales that may be less applicable to small islands with locally unique morphodynamics ...

Correcting Non‐Tidal Atmospheric and Oceanic Loading Displacements at the Observation, Normal Equation, and Parameter Levels in GNSS Data Analysis

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Non‐tidal loading (NTL) introduces surface deformation on the Earth and increases the variability in coordinates measured by space geodetic techniques. Correcting NTL displacements in Global Navigation Satellite Systems (GNSS) analysis has been discussed extensively, commonly at the parameter level.

Transient and Steady‐State Dislocation Creep of Olivine Controlled by Dislocation Interactions at the Isostress Endmember

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The rheological behavior of olivine deforming by dislocation creep controls geodynamic processes that involve steady‐state flow or transient viscosity evolution. Longstanding rheological models applied to both contexts assume that dislocation creep of olivine aggregates occurs close to the isostrain endmember with each grain deforming to the ...
