Automatic Registration of Terrestrial Point Cloud Using Panoramic Reflectance Images
Point Cloud Registration Terrestrial
2015/12/16
Much attention is paid to registration of terrestrial point clouds nowadays. Research is carried out towards improved efficiency and
automation of the registration process. This paper reports a new a...
REFLECTANCE ANISOTROPY MEASUREMENTS USING A PUSHBROOM SPECTROMETER MOUNTED ON UAV AND A LABORATORY GONIOMETER–PRELIMINARY RESULTS
UAV Hyperspectral Pushbroom BRF BRDF Goniometer
2015/9/10
During 2014–2015 we have developed a new method to measure reflectance factor anisotropy using a pushbroom spectrometer mounted on a multicopter UAV. In this paper/presentation we describe the acquisi...
THE CHARACTERISATION OF HEATHER FOLIAGE AND CANOPIES BY HYPERSPECTRAL REFLECTANCE
international importance biodiversity conservation
2015/9/9
Heather dominated uplands form a significant proportion of Scotland’s land area and are of
significant economic and aesthetic value, of international importance for biodiversity conservation, a
hydr...
FOREST REFLECTANCE MODELING IN THE ARCTIC REGION: RESULTS FROM A CASE STUDY IN FINLAND
slow accumulation organic matter
2015/9/9
The Arctic region, defined often as the region north from the polar circle (66o
32’ N), is characterized by
strong variations in sun light conditions - low intensity insolation with a protracted ph...
REFLECTANCE RETRIEVAL IN SHADE USING ADJOINT RADIOSITY
Reflectance Retrieval Adjoint Radiosity
2015/9/8
Current reflectance retrieval algorithms assume the target is illuminated only by sun and
skylight, and neglect the effect of adjacent 3-D surfaces such as trees and buildings and
the impact of non-...
A GENERIC AEROSOL-SURFACE REFLECTANCE RETRIEVAL ALGORITHM FOR MODIS
Advanced preprocessing remotely sensed data
2015/9/8
If given a consecutive set of images of the same region of the Earth obtained from space,
an untrained human will easily solve many of the remote sensing problems, such as
selecting clear-skies area...
ELUCIDATING PHYSIOLOGY OF PLANT MEDIATED EXCHANGE PROCESSES USING AIRBORNE HYPERSPECTRAL REFLECTANCE MEASUREMENTS IN SYNOPSIS WITH EDDY COVARIANCE DATA
Remote Sensing CERES vegetation
2015/9/8
The Carbo Europe Regional Experiment Strategy (CERES), conducted between May and June 2005, aims to determine a spatially
resolved regional balance of carbon dioxide fluxes using different methodolog...
COMPARING THREE CANOPY REFLECTANCE MODELS WITH HYPERSPECTRAL MULTI-ANGULAR SATELLITE DATA
Canopy reflectance models forward modelling radiative transfer
2015/9/8
Studies that compare modelled reflectances with satellite-measured reflectances for different wavelengths and view angles are still
rare. We compared model outputs from three different canopy reflect...
SHOULD WE EXPECT ANOMALOUS DISPERSION IN THE POLARIZED REFLECTANCE OF LEAVES?
Leaf reflectance Polarization Anomalous dispersion
2015/9/8
The light scattered by plant canopies depends in part on the light scattering/absorbing properties of the leaves and is key to
understanding the remote sensing process in the optical domain. Here we ...
MODELLING REFLECTANCE OF URBAN CHESTNUT TREES: A SENSITIVITY ANALYSIS OF MODEL INVERSION FOR SINGLE TREES
radiative transfer model single trees urban environment
2015/9/8
Trees in urban environments have important ecological functions, but often suffer from suboptimal environmental conditions.
Chestnut (Aesculus hippocastanum) is one of the main tree species in German...
REFLECTANCE SPECTROSCOPY IN THE 400-2400 NM TO ASSESS SETTLED DUST IN DIFFERENT URBAN ENVIRONMENTS
Indoor dust loadings Reflectance Spectroscopy Geographical Information System
2015/9/8
The aim of this study was to apply a spectral reflectance approach to account for small amounts of sediment dust in occupied
homes. We examined the method’s ability to predict the gravimetric weight ...
