TL;DR: The results indicated that height deciles of the Finnish birch crown had vertical movements between -10.0 and 5.0 cm compared to the situation at sunset, which demonstrates the potential of terrestrial laser scanning measurements in support of chronobiology.

TL;DR: It is demonstrated that systematic effects in the resulting scanned and matched 3D point clouds can be minimized based on a hybrid orientation procedure, and improved digital surface models can be derived combining the higher density of the matching point cloud and the higher reliability of LiDAR point clouds, especially in the narrow alleys and courtyards of the study site, a medieval city.

TL;DR: By the introduction of on-the-job correction procedures as the one proposed, the systematic errors of TLS can be decreased significantly, making them more suitable to be used as an alternative to single point measurement devices.

TL;DR: It is concluded that the method of the end-to-end system, allowing training on a big variety of classification problems without the need for expert knowledge about neighbourhood features can also successfully be applied to single-point-based classification of ALS point clouds.

TL;DR: In this article, the accuracy of the algorithm is cross validated against reference measurements obtained from terrestrial survey with a total station and shows negligible bias and virtually no depth dependence for the experimental dataset.
