FORSAT: a 3D forest monitoring system for cover mapping and volumetric 3D change detection
(Taylor and Francis Ltd., 2020-08-02)
A 3D forest monitoring system, called FORSAT (a satellite very high resolution image processing platform for forest assessment), was developed for the extraction of 3D geometric forest information from very high resolution ...
Determining pull - out deformations of bonded metal anchors embedded in concrete by means of photogrammetry
(International Society for Photogrammetry and Remote Sensing, 2012)
Chemical anchorages are applied in many engineering implementations, particularly strengthening of reinforced concrete structures. During strengthening procedure; chemical anchorages should be tested, since they supply to ...
Monitoring of a laboratory-scale inland-delta formation using a structured-light system
(Blackwell Publishing Ltd, 2016-06)
A reduced complexity model, which simulates the process of fluvial inland-delta formation, has been developed in a previous study. The results have been compared and validated with a laboratory experiment. This work ...
Precursors of instability in a natural slope due to rainfall: a full-scale experiment
(Springer Heidelberg, 2018-09)
A full-scale landslide-triggering experiment was conducted on a natural sandy slope subjected to an artificial rainfall event, which resulted in mobilisation of 130m(3) of soil mass. Novel slope deformation sensors (SDSs) ...
A precision estimation method for volumetric changes
(IEEE, 2019-06)
Earth surface changes are often computed by comparing the sequences of digital elevation models (DEMs) so called the DEM of difference (DoD) method. We present an operational DEM generation, co-registration and DoD comparison ...
Photogrammetric monitoring of an artificially generated shallow landslide
(Wiley-Blackwell, 2013-06)
An artificial rainfall event was applied to a forested slope in Ruedlingen, northern Switzerland. The experiment triggered a landslide which resulted in mobilising about 130m3 of debris. The event was monitored by a ...
Quality assessment of 3D building data
(Wiley-Blackwell Publishing, 2010-12)
Three-dimensional building models are often now produced from lidar and photogrammetric data. The quality control of these models is a relevant issue both from the scientific and practical points of view. This work presents ...
A generic point error model for TLS derived point clouds
(SPIE-Int Soc Optical Engineering, 2017-06-26)
This work aims at developing a generic and anisotropic point error model, which is capable of computing magnitude and direction of a priori random errors, described in the form of error ellipsoids for each individual point ...
Pre- and post-fire comparison of forest areas in 3D
(Springer Berlin Heidelberg, 2019)
A satellite processing platform for high resolution forest assessment (FORSAT) was developed. It generates the digital surface models (DSMs) of the forest canopy by advanced processing of the very-high resolution (VHR) ...
