Tree Stem Shapes Derived from TLS Data as an Indicator for Shallow Landslides

Tree Stem Diameter Estimation From Volumetric TLS Image Data

Recently, a new method on tree stem isolation using volumetric image data from terrestrial laser scans (TLS) has been introduced by the same authors. The method transfers TLS data into a voxel grid data structure and isolates the tree stems from the overall forest vegetation. While the stem detection method yields on a three dimensional localisation of the tree stems, the present study introduc...

Effect of Tree Roots on Shallow-Seated Landslides

Forest vegetation, especially tree roots, helps stabilize hillslopes by reinforcing soil shear strength. To evaluate the effect of tree roots on slope stability, information about the amount of roots and their strength should be known. A simulation model for the root distribution of Cryptomeria japonica was proposed where the number of roots in each 0.5.cm diameter class can be calculated at ar...

SLOPE PROFILE MORPHOMETRY AS AN INDICATOR FOR SLOPE MOVEMENT

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

Cytotoxicity of Chitosan Derived from Shrimp for Bone Scaffold on Adipose Tissue-Derived Mesenchymal Stem Cells

Application of Tls to Support Landslides Study: Survey Planning, Operational Issues and Data Processing

Terrestrial laser scanning (TLS) technology has recently increased its interest in the geological community for the geometric survey of slopes involved in landslides and for the acquisition of a DSM of rock wall, that can be used for predicting possible paths of falling dawn stones. In particular, the paper deals with this last application, focusing on some open aspects which have devised to be...
