A Study on Factors Affecting Airborne LiDAR Penetration

Nurses’ Perspectives on Factors Affecting Patient Safety: A Qualitative Study

Patient safety is a global concern that involves all healthcare members, so that achieving a high level safe care is responsibility of all healthcare services, particularly nurses. This qualitative study aimed to describe nurses’ perspectives on factors affecting patient safety. We recruited 32 nurses working in teaching hospitals by purposeful sampling method. Data were collected by semi-struc...

Calibrating Airborne Lidar Systems

To fully exploit the potential of LIDAR technology and to consequently achieve maximum accuracy of the laser points on the ground, the entire multi-sensory measurement system should be carefully calibrated. The overall system calibration is a very complex task and includes individual sensor calibration as well as the determination of the sensors’ spatial relationships. High-performance integrat...

Airborne Lidar Bathymetry

Airborne and Spaceborne Lidar

The evolution of lidar, from those early ground-based measurements to our first long-duration spaceborne experiments, is schematically represented in Fig. 13.1. It depicts the first lidars in the 1960s as ground-based, followed by systems first flown in 1969 on small aircraft, and followed in the late 1970s by lidars flown on large aircraft capable of long-range measurements. Starting in 1979, ...

Forest Delineation Based on Airborne LIDAR Data

The delineation of forested areas is a critical task, because the resulting maps are a fundamental input for a broad field of applications and users. Different national and international forest definitions are available for manual or automatic delineation, but unfortunately most definitions lack precise geometrical descriptions for the different criteria. A mandatory criterion in forest definit...
