  1. 21. Deep Learning for Sea-Ice Classification on Synthetic Aperture Radar (SAR) Images in Earth Observation : Classification Using Semi-Supervised Generative Adversarial Networks on Partially Labeled Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Francesco Staccone; [2020]
    Keywords : Earth Observation; Classification; Deep Learning; Convolutional NeuralNetworks; Semi-Supervised Learning; GenerativeAdversarialNetworks; Jordobservation; Klassificering; Djupinlärning; IhopveckladeNeurala Nätverk; Halvövervakad Inlärning; Generativa Fientliga Nätverk;

    Abstract : Earth Observation is the gathering of information about planet Earth’s system via Remote Sensing technologies for monitoring land cover types and their changes. Through the years, image classification techniques have been widely studied and employed to extract useful information from Earth Observation data such as satellite imagery. READ MORE

  3. 22. Assessing the accuracy for area-based tree species classification using Sentinel-1 C-band SAR data

    University essay from SLU/Dept. of Forest Resource Management

    Author : Alberto Udali; [2019]
    Keywords : Sentinel-1; tree species; random forest; linear discrimi-nant analysis; classification;

    Abstract : Forest type (FTY) and tree species classification (SPP) over the Remn-ingstorp test site were performed using ground-based field observations and remote sensing data sources. The field inventory for the forest estate and for the surrounding natural reserve of Eahagen was carried out in 2016. READ MORE

  4. 23. Avalanche Visualisation Using Satellite Radar

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Aron Widforss; [2019]
    Keywords : snow science; avalanche detection; satellite SAR; avanor;

    Abstract : Avalanche forecasters need precise knowledge about avalanche activity in large remote areas. Manual methods for gathering this data have scalability issues. Synthetic aperture radar satellites may provide much needed complementary data. READ MORE

  5. 24. Above-ground biomass estimation in boreal productive forests using Sentinel-1 data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : David Roc Roc; [2019]
    Keywords : synthetic aperture radar SAR ; backscatter intensity; InSAR; interferometric coherence; LIDAR; above-ground biomass; forestry;

    Abstract : Estimation of biomass has high importance for economic, ecologic and climatic reasons due to the multiple ecosystem services offered by forested landscapes. Measurements that are taken in the field incur personal and economic costs. Nevertheless, biomass surveying based on remote sensing techniques offer efficiency thanks to covering large areas.

  6. 25. Modeling of Effective Leaf Area Index

    University essay from SLU/Dept. of Forest Resource Management

    Author : Lina Selin; [2018]
    Keywords : Sentinel-1; tree species; random forest; linear discriminant;

    Abstract : Mapping of e�ective leaf area index (LAIe) over the Swedish boreal forest test site Krycklan (64°N19°E) was performed using ground-based �eld estimates of LAIe and remote sensing data sources. The LAIe data were collected 2017 and 2018 using the LAI-2200 Plant Canopy Analyzer and its later version LAI-2200C Plant Canopy Analyzer. READ MORE
