Flächenhafte Deformationsanalysen mit terrestrischen und Nahbereichslaserscannern: eine Gegenüberstellung anhand von Beispielen
(2014)
Dieser Beitrag stellt einen Überblick über den Ablauf einer flächenhaften Deformationsanalyse basierend auf terrestrischen Laserscannern (TLS) dar, wobei speziell auf die Datenerfassung, Vorverarbeitung und Auswertung ...
Challenges and present fields of action at laser scanner based deformation analyses
(2016-03-31)
Due to improved laser scanning technology, laser scanner based deformation analyses are presently widespread. These deformation analyses are no longer based on individual points representing the deformation of an object ...
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012)
Die dynamische Ozeantopograpie als Differenz zwischen Meeresoberfläche und dem Geoid reflektiert charakteristische Merkmale der Ozeanzirkulation und stellt als gemessene Größe somit eine bedeutende Eingangsgröße in ...
Digital filtering algorithms for decorrelation within large least squares problems
(2012)
The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ...
Accurate georeferencing of TLS point clouds with short GNSS observation durations even under challenging measurement conditions
(2018-08-29)
The accuracy of georeferenced TLS point clouds
is directly influenced by site-dependent GNSS effects, deteriorating
the accuracy of the ground control point coordinate
estimation. Especially under challenging GNSS ...
Investigations on the Influence of Antenna Near-field Effects and Satellite Obstruction on the Uncertainty of GNSS-based Distance Measurements
(2016-03-31)
Antenna near-field effects are one of the accuracy
limiting factors on GNSS-based distance measurements.
In order to analyse these influences, a measurement campaign
at an EDM calibration baseline site with optimum
GNSS ...
On high performance computing in geodesy: applications in global gravity field determination
(2015)
Autonomously working sensor platforms deliver an increasing amount of precise data sets, which are often usable in geodetic applications. Due to the volume and quality, models determined from the data can be parameterized ...
Methods for assimilating remotelysensed water storage changes into hydrological models
(2016)
Understanding physical processes within the water cycle is a challenging issue that requires merging information from various disciplines. The Gravity Recovery And Climate Experiment (GRACE) mission provides a unique ...
Entwicklung einer direkten Georeferenzierungseinheit zur Positionsund Orientierungsbestimmung leichter UAVs in Echtzeit
(2016)
Seit einigen Jahren werden im Bereich der Geodäsie immer häufiger auch Unmanned Aerial Vehicles (UAVs) als kinematische Trägerplattformen eingesetzt. Dazu werden diese mit objekterfassender Sensorik, wie z.B. Digitalkameras ...
Assessing people´s early warning response capability to inform urban planning interventions to reduce vulnerability to tsunamis: case study of Padang City, Indonesia
(2014)
In the last decade, more emphasis is given on the human aspect of early warning or the attribute of “people-centered” early warning systems. This study seeks to better understand the specific conditions that shape people´s ...
