Phan Hien, V. (author), Lindenbergh, R.C. (author), Menenti, M. (author)Monitoring glacier changes is essential for estimating the water mass balance of the Tibetan Plateau. In this study, we exploit ICESat laser altimetry data in combination with the SRTM DEM and the GLIMS glacier mask to estimate trends in change in glacial thickness between 2003 and 2009 on the whole Tibetan Plateau. Considering acquisition...journal article 2017

Vandebroek, Elena (author), Lindenbergh, R.C. (author), van Leijen, F.J. (author), de Schipper, M.A. (author), de Vries, S. (author), Hanssen, R.F. (author)This paper presents a semi-automated approach to detecting coastal shoreline change with high spatial- and temporal-resolution using X-band synthetic aperture radar (SAR) data. The method was applied at the Sand Motor, a “mega-scale” beach nourishment project in the Netherlands. Natural processes, like waves, wind, and tides, gradually...journal article 2017

Shen, Y. (author), Lindenbergh, R.C. (author), Wang, J. (author)A method is introduced for detecting changes from point clouds that avoids registration. For many applications, changes are detected between two scans of the same scene obtained at different times. Traditionally, these scans are aligned to a common coordinate system having the disadvantage that this registration step introduces additional...journal article 2017

Sirmacek, B. (author), Shen, Y. (author), Lindenbergh, R.C. (author), Zlatanova, S. (author), Diakite, A.A. (author)We present a comparison of point cloud generation and quality of data acquired by Zebedee (Zeb1) and Leica C10 devices which are used in the same building interior. Both sensor devices come with different practical and technical advantages. As it could be expected, these advantages come with some drawbacks. Therefore, depending on the...journal article 2016

Sirmacek, B. (author), Lindenbergh, R.C. (author), Wang, J. (author)3D urban models are valuable for urban map generation, environment monitoring, safety planning and educational purposes. For 3D measurement of urban structures, generally airborne laser scanning sensors or multi-view satellite images are used as a data source. However, close-range sensors (such as terrestrial laser scanners) and low cost cameras...journal article 2016

(author)Current 3D data capturing as implemented on for example airborne or mobile laser scanning systems is able to efficiently sample the surface of a city by billions of unselective points during one working day. What is still difficult is to extract and visualize meaningful information hidden in these point clouds with the same efficiency. This...journal article 2016

Wang, J. (author), Lindenbergh, R.C. (author), Shen, Y. (author), Menenti, M. (author)Laser scanning samples the surface geometry of objects efficiently and records versatile information as point clouds. However, often more scans are required to fully cover a scene. Therefore, a registration step is required that transforms the different scans into a common coordinate system. The registration of point clouds is usually conducted...journal article 2016

Sirmacek, B. (author), Lindenbergh, R.C. (author)Recent technological developments help us to acquire high quality 3D measurements of our urban environment. However, these measurements, which come as point clouds or Digital Surface Models (DSM), do not directly give 3D geometrical models of buildings. In addition to that, they are not suitable for fast 3D rendering. Therefore, detection and 3D...journal article 2015
