Airborne laser scanning technological analysis
Airborne Laser Scanning or LIDAR (Light Detection and Ranging) lends new possibilities for the investigation of the terrain surface, especially elevation data, also buildings and other objects modelling. In the article, the technological analysis of this

Automated Classification of Airborne Laser Scanning Point Clouds [PDF]
Making sense of the physical world has always been at the core of mapping. Up until recently, this has always dependent on using the human eye. Using airborne lasers, it has become possible to quickly "see" more of the world in many more dimensions.

FOOTPRINT MAP PARTITIONING USING AIRBORNE LASER SCANNING DATA [PDF]
Nowadays many cities and countries are creating their 3D building models for a better daily management and smarter decision making. The newly created 3D models are required to be consistent with existing 2D footprint maps. Thereby the 2D maps are usually

Detecting overmature forests with airborne laser scanning (ALS)
Building a network of interconnected overmature forests is crucial for the conservation of biodiversity. Indeed, a multitude of plant and animal species depend on forest structural maturity attributes such as very large living trees and deadwood.

Detecting Terrain Stoniness From Airborne Laser Scanning Data †
Three methods to estimate the presence of ground surface stones from publicly available Airborne Laser Scanning (ALS) point clouds are presented. The first method approximates the local curvature by local linear multi-scale fitting, and the second method

Theoretical Lidar Point Density for Topographic Mapping in the Largest Scales [PDF]
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
