Objective landslide detection and surface morphology mapping using high-resolution airborne laser altimetry
A map of extant slope failures is the most basic element of any landslide assessment. Without an accurate inventory of slope instability, it is not possible to analyze the controls on the spatial and temporal patterns of mass movement or the environmental, human, or geomorphic consequences of slides. Landslide inventory maps are tedious to compile, difficult to make in vegetated terrain using c...
متن کاملLandslide Mapping in Vegetated Areas Using Change Detection Based on Optical and Polarimetric SAR Data
Mapping of landslides, quickly providing information about the extent of the affected area and type and grade of damage, is crucial to enable fast crisis response, i.e., to support rescue and humanitarian operations. Most synthetic aperture radar (SAR) data-based landslide detection approaches reported in the literature use change detection techniques, requiring very high resolution (VHR) SAR i...
متن کاملA Geomorphological Model for Landslide Detection Using Airborne Lidar Data
This study analyzes multi-temporal LiDAR data of high accuracy and high resolution by installing a geomorphometric model for extracting landslides. First, two sets of LiDAR data were acquired for before and after a heavy rainfall event. The landslides which took place from 2005 to 2009 were classified automatically by satellite images, and subsequently the landslides were interpreted and edited...
متن کاملEolian deformation detection and modeling using airborne laser altimetry
Monitoring of landscapes or sea bottoms by means of laser altimetry or multibeam results in huge amount of data covering the same area in different epochs. Often stable benchmarks are not available in the area covered. We propose a geodetic/geostatistical method to analyze possible deformations in such area out of time series of data. The method is used for a deformation analysis of six consecu...
متن کاملAirborne mapping using LIDAR
Mapping is a central and common task in robotics research. Building an accurate map without human assistance provides several applications such as space missions, search and rescue, surveillance and can be used in dangerous areas. One application for robotic mapping is to measure changes in terrain volume. In Sweden there are over a hundred landfills that are regulated by laws that says that th...
