Machine-Learning Applications for the Retrieval of Forest Biomass from Airborne P-Band SAR Data
(2020)This study aimed at evaluating the potential of machine learning (ML) for estimating forest biomass from polarimetric Synthetic Aperture Radar (SAR) data. Retrieval algorithms based on two different machine-learning methods, ... -
Performance Evaluation of Phase and Weather-Based Models in Atmospheric Correction With Sentinel-1Data: Corvara Landslide in the Alps
(2020)Phase delay caused by atmospheric effects due to spatial and temporal variations of pressure, temperature, and water vapor content is one of the major error sources in estimation of ground deformation by interferometric ... -
Use of Sentinel-1 radar observations to evaluate snowmelt dynamics in alpine regions
(2020)Knowing the timing and the evolution of the snow melting process is very important, since it allows the prediction of (i) the snowmelt onset, (ii) the snow gliding and wet-snow avalanches, (iii) the release of snow ... -
Changes in climate patterns and their association to natural hazard distribution in South Tyrol (Eastern Italian Alps)
(2020)In Alpine regions changes in seasonal climatic parameters, such as temperature, rainfall, and snow amount have already been observed. Specifically, in the South Tyrol area, meteorological observations indicate that ... -
An inventory-driven rock glacier status model (intact vs. relict) for South Tyrol, Eastern Italian Alps
(2020)Ice presence in rock glaciers is a topic that is likely to gain importance in the future due to the expected decrease in water supply from glaciers and the increase of mass movements originating in periglacial areas. This ... -
Sentinel-1 InSAR Coherence for Land Cover Mapping: A Comparison of Multiple Feature-Based Classifiers
(2020)This article investigates and demonstrates the suitability of the Sentinel-1 interferometric coherence for land cover and vegetation mapping. In addition, this study analyzes the performance of this feature along with ... -
The (f)utility to account for pre-failure topography in data-driven landslide susceptibility modelling
(2020)The aim of most data-driven landslide susceptibility assessments is to generate a map that depicts zones that are prone to future landsliding. The underlying algorithms are usually trained on the basis of a dichotomous ... -
Daily MODIS Snow Cover Maps for the European Alps from 2002 onwards at 250 m Horizontal Resolution Along with a Nearly Cloud-Free Version
(2019)Snow cover dynamics impact a whole range of systems in mountain regions, from society to economy to ecology; and they also affect downstream regions. Monitoring and analyzing snow cover dynamics has been facilitated with ... -
Evaluating Snow in EURO-CORDEX Regional Climate Models with Observations for the European Alps: Biases and Their Relationship to Orography, Temperature, and Precipitation Mismatches
(2019)Climate models are important tools to assess current and future climate. While they have been extensively used for studying temperature and precipitation, only recently regional climate models (RCMs) arrived at horizontal ... -
An Unsupervised Method to Detect Rock Glacier Activity by Using Sentinel-1 SAR Interferometric Coherence: A Regional-Scale Study in the Eastern European Alps
(2019)Rock glaciers are widespread periglacial landforms in mountain regions like the European Alps. Depending on their ice content, they are characterized by slow downslope displacement due to permafrost creep. These landforms ... -
Improving SWE estimation by fusion of snow models with topographic and remotely sensed data
(2019)This paper presents a new concept to derive the snow water equivalent (SWE) based on the joint use of snow model (AMUNDSEN) simulation, ground data, and auxiliary products derived from remote sensing. The main objective ... -
A novel data fusion technique for snow cover retrieval
(2019)This paper presents a novel data fusion technique for improving the snow cover monitoring for a mesoscale Alpine region, in particular in those areas where two information sources disagree. The presented methodological ... -
Ecosystem Services in a Protected Mountain Range of Portugal: Satellite-Based Products for State and Trend Analysis
(2018)Mountains are facing strong environmental pressures, which may jeopardize the supply of various ecosystem services. For sustainable land management, ecosystem services and their supporting functions should thus be evaluated ... -
Soil Roughness Retrieval from TerraSar-X Data Using Neural Network and Fractal Method
(2019)The purpose of this study is to estimate the surface roughness (rms) using TerraSar-X data in HH polarization. Simulation of data is carried out at a wide range of moisture and roughness using the Integral Equation Model ... -
Review of Machine Learning Approaches for Biomass and Soil Moisture Retrievals from Remote Sensing Data
(2015)The enormous increase of remote sensing data from airborne and space-borne platforms, as well as ground measurements has directed the attention of scientists towards new and efficient retrieval methodologies. Of particular ... -
TITAN AS REVEALED BY THE CASSINI RADAR
(2019)Titan was a mostly unknown world prior to the Cassini spacecraft’s arrival in July 2004. We review the major scientific advances made by Cassini’s Titan Radar Mapper (RADAR) during 13 years of Cassini’s exploration of ... -
Estimating tree species diversity from space in an alpine conifer forest: The Rao's Q diversity index meets the spectral variation hypothesis
(2019)Forests cover about 30% of the Earth surface, they are among the most biodiverse terrestrial ecosystems and represent the bulk of many ecological processes and services. The assessment of biodiversity is an important and ... -
On the Automated Mapping of Snow Cover on Glaciers and Calculation of Snow Line Altitudes from Multi-Temporal Landsat Data
(2019)Mapping snow cover (SC) on glaciers at the end of the ablation period provides a possibility to rapidly obtain a proxy for their equilibrium line altitude (ELA) which in turn is a metric for the mass balance. Satellite ... -
A Fractal Algorithm for Surface Roughness Parameters retrieval using Multi -Band/polarization AIRSAR Data
(2019)Surface roughness is an important characteristic in analyzing SAR images and three-dimensional (3D) surfaces that influence the backscattering of electromagnetic waves. This paper proposes an algorithm based on a fractal ... -
Il progetto GreenRisk4Alps: Misure "verdi" per la gestione dei rischi naturali sulle Alpi
(2019)GreenRisk4ALPs: towards the implementation of ecosystem-based solutions for risk management in the Alps. Forests and mountain ecosystems play a crucial role in the mitigation of risks deriving from natural hazards in the ...
