Automated Classification of Airborne Laser Scanning Point Clouds
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. The resulting enormous point clouds serve as data sources for applications far beyond the original mapping purposes ranging from flooding protectio...
متن کاملRasterizing Airborne Laser Scanning Point Clouds by Block Kriging
Airborne laser scanning (ALS) is increasingly becoming a standard method for the collection of dense elevation models, especially in 3D urban mapping. However, automation in processing of ALS point-clouds involves handling huge datasets, irregular point distribution, multiple views, and relatively low textured surfaces. Since raster data structure is the most commonly used data representation m...
متن کاملThe Utility of Image-Based Point Clouds for Forest Inventory: A Comparison with Airborne Laser Scanning
Airborne Laser Scanning (ALS), also known as Light Detection and Ranging (LiDAR) enables an accurate three-dimensional characterization of vertical forest structure. ALS has proven to be an information-rich asset for forest managers, enabling the generation of highly detailed bare earth digital elevation models (DEMs) as well as estimation of a range of forest inventory attributes (including he...
متن کاملIntegrated Change Detection and Classification in Urban Areas Based on Airborne Laser Scanning Point Clouds
This paper suggests a new approach for change detection (CD) in 3D point clouds. It combines classification and CD in one step using machine learning. The point cloud data of both epochs are merged for computing features of four types: features describing the point distribution, a feature relating to relative terrain elevation, features specific for the multi-target capability of laser scanning...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
