See the forest and the trees: Effective machine and deep learning algorithms for wood filtering and tree species classification from terrestrial laser scanning

Isprs Journal of Photogrammetry and Remote Sensing, 2020
Determining tree species composition in natural forests is essential for effective forest management. Species classification at the individual tree level requires fine-scale traits which can be derived through terrestrial laser scanning (TLS) point ...

Terrestrial Laser Scanning Systems

2020
Laser scanning has become a part of the surveying practice during the last three decades of the development of scanning systems. Laser scanning technology is one of the most effective methods of spatial data acquisition and creation of 3D models in the present days.

Landslide site reconstruction with terrestrial laser scanning

2010 18th International Conference on Geoinformatics, 2010
The study of a landside site involves many aspects of data collection and data analysis activities. Among the data to be collected are the site location, the landside orientation, the soil profile, and the vegetation cover. Although these data (such as the topography and the distribution of trees) are 3-dimensional in nature, they are usually collected

Automatic Stem Mapping Using Single-Scan Terrestrial Laser Scanning

IEEE Transactions on Geoscience and Remote Sensing, 2012
The demand for detailed ground reference data in quantitative forest inventories is growing rapidly, e.g., to improve the calibration of the developed models of airborne-laser-scanning-based inventories. The application of terrestrial laser scanning (TLS) in the forest has shown great potential for improving the accuracy and efficiency of field data ...

Basics of Terrestrial Laser Scanning

2019
This chapter introduces the basic concepts of the automatic 3D surveying by means of laser scanning techniques, a methodology developed less than 20 years ago (see, e.g., Boehler et al. 2002) thanks to the technological improvement of the topographical instrumentations, in particular in the movement and in the electronical components.

Terrestrial Laser Scanning

2011
Since the early 2000s terrestrial laser scanning has evolved from a research and development (R&D) topic to a geo-data technology, which is commercially offered by a multitude of land surveying companies and other service providers all over the world. The technology is primarily used for the rapid acquisition of three-dimensional (3D) information of a ...

Target identification in terrestrial laser scanning

Survey Review, 2014
AbstractTarget identification is an important process in terrestrial laser scanner (TLS) measurements; however, due to strong competition between manufacturers, the design of laser scanners is kept secret and is usually strengthened by accompanying proprietary software. Moreover, the target identification algorithms (i.e.

Estimation of degraded grassland aboveground biomass using machine learning methods from terrestrial laser scanning data

, 2020
Aboveground biomass (AGB) is an important indicator for grassland ecosystem assessment, management and utilization. Remote sensing technologies have driven the development of grassland AGB estimation from labor-intensive to highly-efficient.
