Dependency of strains and rotations in geodetic network [PDF]

open access: yes, 2013
At each point of the geodetic network, kinematic\ud quantities are considered: normal strain, shear\ud strain and rotation. This differs from the treatment\ud of deformations on the basis of point movements as\ud the traditional geodetic approach. Strain

OrchardQuant‐3D: combining drone and LiDAR to perform scalable 3D phenotyping for characterising key canopy and floral traits in fruit orchards

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Orchard fruits such as pear and apple are important for ensuring global food security and agricultural economy as they not only provide essential nutrients, but also support biodiversity and ecosystem services. Breeders, growers and plant researchers constantly study desirable tree morphological features and floral characteristics to ensure ...

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

open access: yes, 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

The Datums Transformation for GPS Navigation Measurements Correction

open access: yesمجلة 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 ...

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

open access: yesThe 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.

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

open access: yes, 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

Effects of the Last Quaternary Glacial Forebulge on Vertical Land Movement, Sea‐Level Change, and Lithospheric Stresses

open access: yesReviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract A glacial forebulge is a bending‐related upheaval of the lithosphere outside a glaciated area that co‐occurs to the depression of the lithosphere below an ice sheet. The forebulge of the last glaciation attracted attention over more than one century, but quantitative descriptions on the geometry of the forebulge are rare.

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

open access: yes, 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 ≈

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

open access: yesGeodesy 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.
