GNSS data analysis and updated geodetic velocity field in Greece

Autor: Stylianos Bitharis, Christos Pikridas, Aristeidis Fotiou, Dimitrios Rossikopoulos

In this study an updated crustal velocity field for the Greece area was estimated using a time series analysis that covers a duration of 16 years from 227 Global Navigation Satellite System (GNSS) permanent stations. The GNSS processing was carried o

On 3 March 2021, the Mw6.3 Tyrnavos earthquake shook much of the Thessalia region, leading to extensive damage in many small towns and villages in the activated area. The first main shock was followed in the next day, on 4th of March 2021, by an “e

Publikováno v: Marine Geodesy

In this study, we show how the Global Navigation Satellite System (GNSS)-derived vertical velocities contribute to the correction of tide gauge (TG) measurements used for the sea level rise estimation in Greece. Twelve sites with records of local sea

A local geoid solution for the northern part of Greece is presented based on a recent processing of newly available gravity data in the area 40.25 ≤ /o ≤ 41.00, 22.5 ≤λ ≤ 24.25. The derived gravimetric geoid heights are compared with geoid h

A PROPOSED METHOD FOR THE REDUCTION OF LONG SPATIAL DISTANCES TO A REFERENCE ELLIPSOID

Autor: Aristeidis Fotiou

Publikováno v: Survey Review. 34:183-187

In this paper a method to reduce long spatial distances, up to a few thousands of km, is presented. Comparisons with the results obtained by classical reduction formulae and the very high precision of derived distances from space and satellite geodes
