  1. 1. 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

  2. 2. 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

  3. 3. 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

  4. 4. 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.

  5. 5. Unmanned Aerial Vehicles and remote sensing in search and rescue missions in Sweden

    University essay from KTH/Fastigheter och byggande

    Author : ioannis ioannidis; [2018]
    Keywords : UAV Drones;

    Abstract : This paper gives a thοrοugh lοοk in the use οf Unmanned Aerial Vehicles (UAV) in search and rescue missiοns. The οbjective is tο identify, thrοugh a literature review, all types οf UAV, the available remοte sensοrs that can be mοunted in a UAV and what type οf data each sensοr prοvides, the methοdοlοgy οn flight planning and what is the regulatοry framewοrk, guidelines and limitatiοns, οf UAV flight in sοme οf the biggest cοuntries wοrldwide and in specific fοr the Eurοpean Uniοn and Sweden.
