Canopy structural modeling using object-oriented image classification and laser scanning [PDF]
, 2008 A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Tracking the built status of MEP works: Assessing the value of a Scan-vs-BIM system [PDF]
, 2014 Mechanical, electrical, and plumbing (MEP) works constitute a large portion of construction costs and thus need to be appropriately tracked. Assessment of the built status of MEP works in construction projects is however typically limited to ...

Advanced Materials, EarlyView.This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...

Importance of DTM accuracy, precision and acquisition technique for estimating contributing areas of post-fire erosion at the slope and catchment scale [PDF]
, 2011 Wildfires are a frequent phenomenon in Portugal, affecting over 300.000 ha in dry years like 2003 and 2005. Directly and/or indirectly, wildfires can strongly enhance the hydrological response and associated sediment losses and, thereby, negatively ...

Theoretical Lidar Point Density for Topographic Mapping in the Largest Scales [PDF]
, 2010 When ordering LiDAR data, LiDAR point density per surface unit is important information with decisive influence on the price of the LiDAR survey. The paper first deals with the theoretical calculation of the minimum LiDAR point density, necessary for the

Terrestrial laser scanning in monitoring of anthropogenic objects
Geodesy and Cartography, 2017 The registered xyz coordinates in the form of a point cloud captured by terrestrial laser scanner and the intensity values (I) assigned to them make it possible to perform geometric and spectral analyses.

Maximum likelihood parametric reconstruction of forest vertical structure from inclined laser quadrat sampling. [PDF]
, 2014 Forest vertical structure is critical to ecological function, and provides a crucial link to air- and spaceborne remote sensing (including LiDAR), but is difficult to measure from the ground.

Terrestrial laser scanning for tree parameters inventory
IOP Conference Series: Earth and Environmental Science, 2018 Presently, the application of Terrestrial Laser Scanning (TLS) technique in forest inventory is becoming widely spread due its high level of accuracy. It is able to provide precise and detailed tree attributes. This study aims to determine tree attributes from point cloud data captured from TLS and to validate the estimated tree attributes by using the
