Optimized background suppression in near field lidar telescopes [PDF]
, 2003 It is shown that a tilted slit in the focal plane of the lidar telescope limits the telescopes field of view efficiently and suppresses the background in the lidar signal by up to an order of magnitude better than a circular ...

DTM GENERATION WITH UAV BASED PHOTOGRAMMETRIC POINT CLOUD [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Nowadays Unmanned Aerial Vehicles (UAVs) are widely used in many applications for different purposes. Their benefits however are not entirely detected due to the integration capabilities of other equipment such as; digital camera, GPS, or laser scanner ...

Journal of Quaternary Science, EarlyView.ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Accuracy of a DTM derived from full-waveform laser scanning data under unstructured eucalypt forest: a case study [PDF]
, 2010 A Digital Terrain Model (DTM) is fundamental for extracting several forest canopy structure metrics from data acquired with small-footprint airborne laser scanning (ALS).

Optimisation of LiDAR derived terrain models for river flow modelling [PDF]
Hydrology and Earth System Sciences, 2009 Airborne LiDAR (Light Detection And Ranging) combines cost efficiency, high degree of automation, high point density of typically 1–10 points per m<sup>2</sup> and height accuracy of better than ±15 cm.

A talus rock glacier in Nantlle Valley, North Wales
Journal of Quaternary Science, EarlyView.ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Integration of LIDAR and IFSAR for mapping [PDF]
, 2004 LiDAR and IfSAR data is now widely used for a number of applications, particularly those needing a digital elevation model. The data is often complementary to other data such as aerial imagery and high resolution satellite data.

People and Nature, EarlyView.Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

An assessment of the use of airborne LiDAR for estimating growth of Sitka spruce (Picea sitchensis) plantation forestry at Kielder Forest, UK [PDF]
, 2007 A growing need exists for the collection of accurate and up-to-date information on forest growth rates for management purposes. Recent studies indicate that airborne laser scanning (ALS) offers a quicker and more cost-effective approach than the ...
