The effect of GNSS reference station number on determining crustal deformations: a case study for October 23, 2011, Mw 7.1 Van earthquake

Geomatics, Natural Hazards & Risk
This study explores the impact of the selected GNSS reference station numbers on determining horizontal and vertical coseismic deformations resulting from the October 23, 2011, Mw 7.1 Van Earthquake in Eastern Anatolia, near Van city center.

Some key facts for the realization of a modern National Geodetic Reference System/Frame: The Hellenic case [PDF]

Micro, Macro & Mezzo Geoinformation
The realization of a modern National Geodetic Reference System/Frame (NGRSF) for each country plays a crucial role in many applications, such as cadastre, public works, and, lately, the monitoring of climate change (at least at the local scale).

The Importance of the Coordinate Transformation Process in Using Heterogeneous Data in Coastal and Marine Geographic Information System

Journal of Marine Science and Engineering, 2020
Coastal and Marine Geographic Information Systems (CMGISs) permit to collect, manage, and analyze a great amount of heterogeneous data concerning coastal, sea, and ocean environments, e.g., nautical charts, topographic maps, remotely sensed images.

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

The Datums Transformation for GPS Navigation Measurements Correction

مجلة بغداد للعلوم, 2008
The GPS navigation measurements become more widely used in many civilian and scientific application. All GPS navigation data holds many errors, the main error sources arise from the geodetic Datum variation when user apply the GPS measurements with the ...

Aquatic reflectance derived from Sentinel‐2 Multispectral Imager data for inland waters in the conterminous United States

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Satellite‐based earth observation is a robust tool for tracking change in ecosystems. While terrestrially focused applications of remote sensing have empowered wide adoption for research and management, remote sensing of inland aquatic ecosystems remains comparably nascent.

A Mass Conservation Model to Study the Evolution of Coastal Soft Cliffs Driven by Sea Level Rise Over Multi‐Century Timescales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Soft cliffed coasts are particularly vulnerable to erosion and their retreat depends on environmental, geological and geomechanical factors. In this work, we use a mathematical modeling approach to understand effects of future global sea level rise on these coasts over multiple centuries.

Multispectral Surface Reflectance as an Indicator of Groundwater Depth for Salt Crust Systems: Insights From the Bonneville Salt Flats, Utah

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Bonneville Salt Flats (BSF) in northwestern Utah, USA, has experienced changes in area, thickness, and hydrology over the past century. This study investigates the relationship between multispectral Halite Index (HI) values, which are sensitive to halite moisture content, from Landsat and Sentinel‐2 imagery and groundwater depth (GWD ...
