The united geodetic vertical network of Latvia and Lithuania
Geodesy and Cartography, 2012 A unified and continuous national vertical network is the back-bone for geodesy, cartography, civil engineering and global positioning. International institutions are working to reach homogenous and unified vertical datum all around the globe.

Restoration Ecology, EarlyView.Sea‐level‐rise and alterations to natural hydrology have contributed to coastal land loss. To combat coastal land loss and maintain the ecosystem services provided by marshes, marsh creation has been broadly implemented. Marsh creation projects can be performed in conjunction with the construction of elevated terrestrial ridges that seek to mimic ...

Evaluation of grace-based combined geopotential model over the Baltic countries
Geodesy and Cartography, 2012 Nowadays, many geodetic and engineering applications require that the two essential components of the vertical positioning – the height and the corresponding reference surface (geoid), are determined precisely.

Estimating the greenhouse gas emission abatement potential of tidal introduction in Australia
Restoration Ecology, EarlyView.Abstract Introduction Coastal wetlands store higher amounts of organic carbon and sequester it at higher rates in soil relative to terrestrial ecosystems. However, they have been extensively drained, excavated, or modified, often to allow agriculture. Restoring degraded coastal wetlands can be an important contribution to climate change mitigation by ...

ISPRS International Journal of Geo-Information, 2020 This investigation evaluates the performance of digital terrain models (DTMs) generated in different vertical datums by aerial LiDAR and unmanned aerial vehicle (UAV) photogrammetry techniques, for the determination and validation of local geoid models ...

Restoration Ecology, EarlyView.Abstract Objective The Dutch Slough Tidal Restoration project in the Sacramento‐San Joaquin Delta involves flooding of delta lands; however, concerns have been raised that such flooding will increase the hydraulic pressures on subsided adjacent islands and threaten levee stability.

Intercontinental height datum connection with GOCE and GPS-levelling data
Journal of Geodetic Science, 2012 In this study an attempt is made to establish height system datum connections based upon a gravity field and steady-state ocean circulation explorer (GOCE) gravity field model and a set of global positioning system (GPS) and levelling data. The procedure

Sedimentology, EarlyView.ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Análisis de la evolución temporal del datum vertical brasileño de Imbituba
Revista Cartográfica, 2019 Actualmente, los temas más centrales de Geodesia se vinculan a la provisión de un Sistema de Referencia Global único, al que puedan vincularse de forma unívoca y con exactitud los cambios globales de carácter geométrico y físico.
