Alignment of Hyperspectral Imagery and Full-waveform Lidar Data for Visualisation and Classification Purposes
The overarching aim of this paper is to enhance the visualisations and classifications of airborne remote sensing data for remote forest surveys. A new open source tool is presented for aligning hyperspectral and full-waveform LiDAR data. The tool produces coloured polygon representations of the scanned areas and aligned metrics from both datasets. Using data provided by NERC ARSF, tree coverag...
متن کاملProcessing Full-waveform Lidar Data: Modelling Raw Signals
Unlike airborne multi-echo laser scanner systems, full-waveform systems are able to digitize and record the entire backscattered signal of each laser pulse. It has been demonstrated that decomposing the return waveforms into a mixture of Gaussian components was suitable. In this paper, we focus on the improvement of peak detection and of raw signal modelling. Refined peak detection greatly incr...
متن کامل3D Modelling of Individual Trees Using Full-waveform Lidar
For the last few decades, analysis of forest area has been conducted using remote sensing techniques such as aerial photogrammetry, satellite imagery, synthetic aperture radar and lidar. Airborne laser scanning in particular offers a cost-effective, versatile, operationally flexible and robust sampling tool for forest management. There is a growing industry trend towards techniques of ‘precisio...
متن کاملTerrain Roughness Parameters from Full-waveform Airborne Lidar Data
As an active remote sensing technique airborne laser scanning (ALS) is able to capture the topography with high precision even for densely forested areas. Due to the high pulse repetition frequency of up to 400 kHz a high sampling rate on the ground can be achieved, which allows the description of the terrain surface in decimeter scale. In this contribution two approaches to characterize terrai...
متن کاملLand Classification of Wavelet-compressed Full-waveform Lidar Data
Given sufficient data storage capacity, today’s full-waveform LiDAR systems are able to record and store the entire laser pulse echo signal. This provides the possibility of further analyzing the physical characteristics of the reflecting objects. However the size of the captured data is enormous and currently not practical. Thus arises the need for compressing the waveform data. We have develo...
