Analysis of a Relative Offset between the North American and the Global Vertical Datum in Gravity Potential Space

open access: yesRemote Sensing, 2023
The accurate estimation of the zero-height geopotential level in a local vertical datum (LVD) is critical for linking traditional height reference systems to a global height system.

Estimation of strain accumulation of densification network in Northern Marmara Region, Turkey [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2010
Strain analysis is one of the methods for the kinematic analysis of the repeated geodetic measurements. In order to derive strain accumulation in Marmara Region, different institutions carried out several Global Positioning System (GPS) campaigns in 1999

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

open access: yes, 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

The review and development of a modern GNSS network and datum in Uzbekistan

open access: yesGeodesy and Geodynamics, 2017
This study is focused on the discussion of a modern GNSS network and datum in Uzbekistan. Considering the significance difference (up to 200 m) in positions of the local ellipsoidal datum and the global datum, the precise transformation parameters ...
