TESTING OF LAND COVER CLASSIFICATION FROM MULTISPECTRAL AIRBORNE LASER SCANNING DATA
multi-wavelength ALS texture analysis classification data fusion laser intensity land cover mapping
2016/11/23
Multispectral Airborne Laser Scanning provides a new opportunity for airborne data collection. It provides high-density topographic surveying and is also a useful tool for land cover mapping. Use of a...
MULTISPECTRAL AIRBORNE LASER SCANNING FOR AUTOMATED MAP UPDATING
Laser scanning Lidar Multispectral Point cloud Mapping Automation Updating Change detection
2016/7/27
During the last 20 years, airborne laser scanning (ALS), often combined with multispectral information from aerial images, has shown its high feasibility for automated mapping processes. Recently, the...
ASSESSING EFFECTS OF LASER POINT DENSITY ON BIOPHYSICAL STAND PROPERTIES DERIVED FROM AIRBORNE LASER SCANNER DATA IN MATURE FOREST
Airborne laser scanner Canopy density Canopy height Pulse density
2015/11/10
Canopy height distributions were created from small-footprint airborne laser scanner data for mature coniferous forest in two forest areas in Norway. In total, 82 and 70 georeferenced field sample plo...
SEMI-BLIND SOURCE SEPARATION FOR ESTIMATION OF CLAY CONTENT OVER SEMI-VEGETATED AREAS,FROM VNIR/SWIR HYPERSPECTRAL AIRBORNE DATA
Hyperspectral remote sensing Semi-Blind source separation Non-Negative Matrix Factorization partial least squares regression clay content semi-vegetated pixels
2015/9/21
The applicability of Visible, Near-Infrared and Short Wave Infrared (VNIR/SWIR) hyperspectral imagery for soil property mapping decreases when surfaces are partially covered by vegetation. The objecti...
AIRBORNE HYPERSPECTRAL REMOTE SENSING FOR IDENTIFICATION GRASSLAND VEGETATION
Vegetation Mapping Hyperspectral Image Classification Maximum Likelihood Classifier Random Forest Support Vector Machine Open Landscape
2015/9/21
In our study we classified grassland vegetation types of an alkali landscape (Eastern Hungary), using different image classification methods for hyperspectral data. Our aim was to test the applicabili...
Target detection algorithm for airborne thermal hyperspectral data
Thermal Hyperspectral LWIR (Long Wave Infrared) Constrained Energy Minimization (CEM) Minimum Noise Fraction (MNF)
2014/12/15
Airborne hyperspectral imaging is constantly being used for classification purpose. But airborne thermal hyperspectral image usually is a challenge for conventional classification approaches. The Telo...
