van Zwieten, G.J. (author)A vital component in the management of seismic hazard is the study of past seismic events. Classically, this has been the domain of seismology, which studies the dynamic manifestations of the event to infer properties such as epicenter and moment magnitude. More recently it has become possible to perform similar analyses on the basis of the...doctoral thesis 2023

Dun, H. (author)Accurate position solutions are in high demand for many emerging applications. Global navigation satellite systems (GNSS), however, may not meet the required positioning performance, especially in urban environments, due to multipath and weak received power of the GNSS signal that can be easily blocked by surrounding objects. To achieve a high...doctoral thesis 2021

Widyaningrum, E. (author)A base map provides essential geospatial information for applications such as urban planning, intelligent transportation systems, and disaster management. Buildings and roads are the main ingredients of a base map and are represented by polygons. Unfortunately, manually delineating their boundaries from remote sensing data is time consuming and...doctoral thesis 2021

Yang, M. (author)Multi-epoch Synthetic Aperture Radar Interferometry (InSAR) is widely used to estimate displacements of selected scatterers from phase observations. However, their interpretation needs a connection to objects in the real world. <br/><br/>To associate InSAR scatterers to their corresponding geo-objects, it is necessary to (i) accurately estimate...doctoral thesis 2020

Zhou, K. (author)3D city models are increasingly used to maintain and improve urban infrastructure. Keeping 3D city models accurate and up-to-date is essential for municipalities to make decisions in a time of strongly increasing urbanization. 3D information provided by airborne laser scanning (ALS) is widely used for generating 3D city models. However, ALS data...doctoral thesis 2020

Özer, I.E. (author)Flood defense systems are critical in protecting against catastrophic events which often lead to significant damage, fatalities or substantial socio-economic and environmental impact. Even though levees form a significant part of the existing flood defense systems, there is a limited knowledge of the different levee behavior processes and the...doctoral thesis 2020

Molijn, R.A. (author)In this study, research on productivity and land cover monitoring is presented, with a focus on sugarcane, based on space-based remote sensing observations that were collected by Synthetic Aperture Radar (SAR) and optical sensors. The study aims to provide new insights into techniques and methodologies that allow for cost-efficient monitoring of...doctoral thesis 2020

Dheenathayalan, P. (author)Time-series synthetic aperture radar interferometry (InSAR) has evolved into a widely preferred geodetic technique for measuring topography and surface deformation of the earth. In the last decades, time-series InSAR methodologies were developed to extract information from persistent scatterers (PS) and distributed scatterers (DS). Methodologies...doctoral thesis 2019

Ekkelenkamp, H. (author)Met hun grafische weergave van de werkelijkheid hebben kaarten al eeuwenlang tot de verbeelding gesproken. Grote veranderingen rond 1800 op nationaal en koloniaal gebied hebben de wereldwijde vraag naar betrouwbare kaarten aanzienlijk doen toenemen. Met “Indonesië op de kaart” is onderzocht hoe de Indonesische archipel in de periode 1800-1990 in...doctoral thesis 2019

Velsink, H. (author)The subject of this study is deformation analysis of the earth's surface (or part of it) and spatial objects on, above or below it. Such analyses are needed in many domains of society. Geodetic deformation analysis uses various types of geodetic measurements to substantiate statements about changes in geometric positions.<br/><br/>Professional...doctoral thesis 2018

Samiei Esfahany, S. (author)During the last decades, time-series interferometric synthetic aperture radar (InSAR) has emerged as a powerful technique to measure various surface deformation phenomena of the earth. Early generations of time-series InSAR methodologies, i.e. Persistent Scatterer Interferometry (PSI), focused on point targets, which are mainly man-made features...doctoral thesis 2017

Chang, L. (author)Satellite radar interferometry (InSAR) is a precise and efficient technique to monitor deformation on Earth with millimeter precision. Most InSAR applications focus on geophysical phenomena, such as earthquakes, volcanoes, or subsidence. Monitoring civil infrastructure with InSAR is relatively new, with potential for operational applications,...doctoral thesis 2015

Mahapatra, P.S. (author)For the past two decades, interferometric synthetic aperture radar (InSAR) has been used to monitor ground deformation with subcentimetric precision from space. But the applicability of this technique is limited in regions with a low density of naturally-occurring phase-coherent radar targets, e.g. vegetated nonurbanized areas. Third-party end...doctoral thesis 2015

Van Leijen, F.J. (author)The Earth's surface is continuously deforming due to natural and anthropogenic processes, such as tectonics, landslides, oil and gas extraction, and groundwater level changes. Persistent Scatterer Interferometry is a technique that provides measurements of this surface motion based on satellite radar images. The technique uses the persistent...doctoral thesis 2014

Caro Cuenca, M. (author)Radar interferometry (InSAR) is a valuable tool to measure surface motion. Applying time series techniques such as Persistent Scatterer Interferometry (PSI), InSAR is able to provide surface displacements maps with mm-precision. However, InSAR can still be further optimized, e.g. by exploiting spatial characteristics of the signal of interest....doctoral thesis 2012

Ketelaar, VBH (author)The start of hydrocarbon production in the 1960s in the northeastern part of the Netherlands has resulted in subsidence of the ground level, which has been estimated from periodic leveling campaigns. Although leveling is a precise and reliable technique for subsidence monitoring, it is labor intensive, expensive and poses a safety risk since...doctoral thesis 2008
