INTERSEISMIC DEFORMATION ACROSS THE EASTERN ALTYN TAGH FAULT FROM INSAR MEASUREMENTS
InSAR Altyn Tagh fault Interseismic deformation Slip rate
2018/5/15
As a new type of earth observation technique, InSAR has a lot of advantages, such as all-weather, all-time, high precision, high density, wide coverage and low cost. It has been widely used in deforma...
ACCURACY OF MEASUREMENTS IN OBLIQUE AERIAL IMAGES FOR URBAN ENVIRONMENT
Aerial Oblique Images Accuracy Urban Mapping
2016/10/14
Oblique aerial images have been a source of data for urban areas for several years. However, the accuracy of measurements in oblique images during this time has been limited to a single meter due to t...
A REVIEW ON LEGAL TRACEABILITY OF GNSS MEASUREMENTS IN THE MALAYSIAN CADASTRAL PRACTICE
Legal Traceability Cadastre Network RTK MyRTKnet
2016/10/14
As the dependency on Global Navigation Satellite System (GNSS) in surveying has been growing over the years, the need for legal traceability of GNSS measurements has become a significant matter. In Ma...
First GPS measurements across the Central-Western Mediterranean area
GPD Mediterranean geodynamics
2015/10/8
This paper concerns the displacement field of the central-western part of the Mediterranean basin estimated by the analysis of three repeated GPS surveys (1995, 1996 and 1997) consisting of 8 sites of...
Algorithms for the inversion of lidar signals: Rayleigh-Mie measurements in the stratosphere
lidar dial ozone aerosol temperature
2015/10/8
We report the features and the performances of the algorithms, developed at the Lidar Station of L'Aquila, for retrieving atmospheric parameters and constituents from elastic lidar signals. The algori...
Latest improvements for the echo sounding system of the Italian radar glaciological group and measurements in Antarctica
radioglaciology ground penetrating radar ice thickness measurements
2015/10/8
Radio echo sounding is an active remote-sensing method using electromagnetic wave penetration in a particular medium such as ice and permits the measurements of its thickness, the level of the bedrock...
Measurements of vector magnetic anomalies on board the icebreaker Shirase and the magnetization of the ship
shipboard three component magnetometer vector measurements of the geomagnetic field ship's permanent magnetization ship's induced magnetic field
2015/10/8
Vector measurements of the geomagnetic field have been made in the South Indian Ocean since 1988 when a Shipboard Three Component Magnetometer (STCM) was installed on board the icebreaker Shirase by t...
Tornillo seismic events at Galeras volcano, Colombia: a summary and new information from broadband three-component measurements
volcanoes seismic events broadband record tornillos Galeras volcano
2015/10/8
Long-duration events have been recorded at several active, andesitic volcanoes. Their main characteristics are a single, sharp frequency peak, and an exceptionally long coda. Because their seismograms...
The anatomy of a tornillo: puzzles from three-component measurements at Galeras volcano (Colombia)
Galeras tornillo polarizations analytic function parametrization
2015/10/8
Many of the recent ash eruptions of Galeras volcano (Colombia) have been preceded by tornillos. These unusual seismic events of unknown origin have screw-like profiles on seismograms and can last up t...
