Extraction of Digital Terrain Model (DTM) over vegetated area in tropical rainforest using LiDAR

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
This paper presents investigations on the combination effect of landcover types, ground filtering approach and interpolation methods on Digital Terrain Model (DTM) generated from airborne LiDAR over vegetated area in tropical environment. The study area is separated into three landcover types i.e. oil palm, mangrove and mixed forest.

Geomorphic change detection in small Alpine basins using LiDAR DTMs [PDF]

, 2013
Morphological change evaluation of earth surface through time is an important task in environmental monitoring and risk management. Methods devoted to the assessment of geomorphic changes can be used to identify geomorphologically unstable areas, to quantify processes intensity, and to compute sediment budgets.

Geomorphic change detection using LiDAR DTMs in two small basins of the Italian Alps.

2013
The description and quantification of landscape changes as modulated by geomorphic processes, at different spatial and temporal scales, constitute the core of modern geomorphic research. The high resolution and accuracy of currently available airborne digital terrain models (DTMs) allow the development of new methods for the quantitative monitoring of ...
