A new methodology to manage Italian geodetic datums of the cadastral systems and of the historic maps [PDF]

, 2013
Cadastral maps represent the result of the highest scale survey of any region. They are not topographic maps. Their goal is to show the property system of the mapped area, so any topographic element that is important for this aspect is shown while others

Unveiling the Floodplain River‐Lake Hydrological Interactions by SWOT Observations

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The bidirectional exchange between rivers and floodplain lakes is critical for regional hydrology, nutrient cycling, and ecosystem management. However, observing the two‐dimensional water surface elevation (WSE) fields that govern these interactions remains a long‐standing challenge, limiting understanding of hydraulic regime shifts.

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

Long-term and recent changes in sea level in the Falkland Islands [PDF]

, 2010
Mean sea level measurements made at Port Louis in the Falkland Islands in 1981-2, 1984 and 2009, together with values from the nearby permanent tide gauge at Port Stanley, have been compared to measurements made at Port Louis in 1842 by James Clark Ross.

Deep learning‐based high‐throughput detection of flowered maize (Zea mays L.) plots from UAS imagery across environments

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Flowering time is a critical phenological trait in maize (Zea mays L.) breeding programs. Traditional measurements for assessing flowering time involve semi‐subjective and labor‐intensive manual observation, limiting the scale and efficiency of genetics and breeding improvement.

Improving Olive Yield Prediction Using Landsat Multispectral Data and Advanced Ensemble Learning in Tunisia

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Olive cultivation is a key agricultural activity in Mediterranean regions, yet its yield is highly sensitive to the impacts of climate change. Accurately predicting olive yield using optical remote sensing and data‐driven models remains a challenging task.

The Rate of U.S. Coastal Sea‐Level Rise Doubled in the Past Century

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract A recent report released by the U.S. Department of Energy concludes that U.S. tide‐gauge data in aggregate provide no evidence for relative sea‐level (RSL) acceleration above the historical mean trend. However, that conclusion rests largely on cursory analysis of a small number of tide‐gauge records that are known to be unrepresentative of ...

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 ...

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 ...
