New High-resolution Field Surveying Methods for Validation of Crown Attributes from 3d Scanning Laser Data

High density airborne LiDAR data has been used to provide detailed information on tree canopy structure. Recent research has reported that it is difficult to determine where the LiDAR data errors appear on the tree crown, as the returns generally underestimate tree height. This study introduces a novel way to assess vertical and horizontal patterns of airborne LiDAR data error using an error ma...

Conditional Random Fields for Airborne Lidar Point Cloud Classification in Urban Area

Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...

Methodology for error analysis and simulation of lidar aerosol measurements.

We present a methodology for objective and automated determination of the uncertainty in aerosol measurements made by lidar. The methodology is based on standard error-propagation procedures, a large data base on atmospheric behavior, and considerable experience in processing lidar data. It yields algebraic expressions for probable error as a function of the atmospheric, background lighting, an...

The Effects of Laser Reflection Angle on Radiometric Correction of the Airborne Lidar Intensity Data

Radiometric correction (RC) of the airborne Light Detection And Ranging (LiDAR) intensity data has been studied in the last few years. The physical model of the RC relies on the use of the laser range equation to convert the intensity values into the spectral reflectance of the reflected objects. A number of recent studies investigated the effects of the LiDAR system parameters (i.e. range, inc...

Remote sensing of vertical distributions of smoke aerosol off the coast of Africa

[1] In 2004 NASA plans to launch the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations— CALIPSO mission, with a two-wavelength lidar aboard. CALIPSO will fly in formation with the Moderate Resolution Imaging Spectro-Radiometer (MODIS) on the Aqua satellite. Here we present inversions of combined aircraft lidar and MODIS data to study the properties of smoke off the southwest co...
