Klingbeil, Lasse; Kuhlmann, Heiner (2014)Dieser Artikel bietet einen Überblick über die Sensoren, die in kinematischen Anwendungen zur Bestimmung der Trajektorie einer bewegten Sensorplattform verwendet werden können. Dabei wird insbesondere darauf eingegangen, ... -
Separablity of deformations and measurements noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
Li, Lihua (2012)The separation of the deformations and measurement noise of GPS coordinate time series and accuracy improvement of GPS real-time coordinates are major aspects of the thesis. In order to reduce the influence of the colored ... -
Sequential learning using incremental import vector machines for semantic segmentation
Roscher, Ribana (2013)We propose an innovative machine learning algorithm called incremental import vector machines that is used for classification purposes. The classifier is specifically designed for the task of sequential learning, in which ... -
Simulated satellite formation flights for detecting the temporal variations of the Earth's gravity field
Elsaka, Basem (2010)In this thesis, the concept of satellite formation flight (SFF) is studied by means of simulated satellite observations. With various formation types enabling inter-satellite measurements in various directions (e.g. ... -

Singular Value Decomposition and Cluster Analysis as Regression Diagnostics Tools in Geodetic VLBI
Vennebusch, Markus (2008)It is well known that high-leverage observations significantly affect the estimation of parameters. So far, mainly redundancy numbers have been used for the detection of single high-leverage observations or of single ... -
Socio-environmental impacts of settlement growth under conditions of fostered infill development: A methodological framework for a multicriteria assessment
Schetke, Sophie (2013)The major objective of this study is to analyze socio-environmental conditions under which a sustainable and resource-preserving settlement development can be promoted and to assess respective impacts of greenfield and ... -
Spatio-temporal Correlations of Terrestrial Laser Scanning: Raumzeitliche Korrelationen beim terrestrischen Laserscanning
Kauker, Stephanie; Holst, Christoph; Schwieger, Volker; Kuhlmann, Heiner; Schön, Steffen (2016)This contribution investigates correlations in terrestrial laser scanning on the scientific level. It summarizes recent approaches to model correlations, to develop measurement scenarios for the determination of correlations ... -
Stadtumbau im Konsens!?: zur Leistungsfähigkeit und Fortentwicklung des städtebaulichen Instrumentariums unter Schrumpfungsbedingungen
Friesecke, Frank (2008)Die Aufgabe des Umbaus der Städte leitet einen grundlegenden Paradigmenwechsel in der Stadtplanung von der Steuerung der Stadtentwicklung unter Wachstumsbedingungen zur Umstrukturierung und Anpassung unter Schrumpfungsbedingungen ... -
Statistical signal decomposition techniques for analyzing time-variable satellite gravimetry data
Forootan, Ehsan (2014)The time-variable gravity fields from the Gravity Recovery and Climate Experiment (GRACE) satellite mission provide valuable information about total water storage variations on a global scale. This quantity is difficult ... -
Stochastic modeling of altimetric sea surface height measurements - refined AR models from iterative residual analysis
Brockmann, Jan Martin; Schuh, Wolf-Dieter (2016) -
Survey Configuration for Terrestrial Laser Scanning: Aufnahmekonfiguration für Terrestrisches Laserscanning
Wujanz, Daniel; Holst, Christoph; Neitzel, Frank; Kuhlmann, Heiner; Niemeier, Wolfgang; Schwieger, Volker (2016)Despite the enormous popularity of terrestrial laser scanners in the field of geodesy and related sciences the vital task of viewpoint planning is mostly considered intuitively. In contrast to established acquisition ... -
Towards the Development of a Continuous Spatio-Temporal Finite Element Based Representation of the Mean Sea Surface
Borlinghaus, Moritz; Neyers, Christian; Brockmann, Jan Martin (2022)The mean sea surface has an important role both in the calculation of the mean dynamic topography and in the area of sea level change as a reference surface. This paper presents a new approach to estimate a continuous ... -
The use of topographic isostatic mass information in geodetic applications
Makhloof, Atef Abd-Elhakeem (2008)The gravity field effects of the topographic-isostatic masses represent an important information of the high-frequent part of the gravity field. In this work the physical-mathematical basics of the classical topographic-isostatic ... -
Vehicle Tracking and Motion Estimation Based on Stereo Vision Sequences
Barth, Alexander (2013)<td>In this dissertation, a novel approach for estimating trajectories of road vehicles such as cars, vans, or motorbikes, based on stereo image sequences is presented. Moving objects are detected and reliably tracked in ... -
Visual Odometry and Sparse Scene Reconstruction for UAVs with a Multi-Fisheye Camera System
Schneider, Johannes (2020)Autonomously operating UAVs demand a fast localization for navigation, to actively explore unknown areas and to create maps. For pose estimation, many UAV systems make use of a combination of GPS receivers and inertial ... -
Visual Place Recognition in Changing Environments
