1. 1. Differens i volym mellan skördardata och laserdata i slutavverkningsbestånd

   University essay from SLU/School for Forest Management

   Author : Sarah Olofsson; Felix Östlund; [2023]
   Keywords : flygburen laserskanning; fjärranalys; slutavverkningsbestånd; skördare;

   Abstract : Sedan den flygburna nationella laserskanningen påbörjades 2009 har Skogliga grunddata blivit ett viktigt verktyg för de verksamma i skogsbranschen både tidsmässigt, praktiskt och ekonomiskt. Lantmäteriet, Skogsstyrelsen och Sveriges lantbruksuniversitet påbörjade 2018 en andra nationell skanningsomgång. READ MORE

3. 2. Petrography of impactites from the Dellen impact structure, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Robert Mroczek; [2023]
   Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

   Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

4. 3. Characterization of Landscape Structures and Precipitation in relation to Flooding events in Pampa Deprimida : A Minor Field Study in Argentina

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Linnea Svärd; [2023]
   Keywords : Pampeana hydrology; flood risk mapping; runoff; infiltration; precipitation; SCSCN; remote sensingg; Hydrologi på Pampas; kartläggning av översvämningsrisker; avrinning; infiltration; nederbörd; SCS-CN; fjärranalys; Hidrología de la Pampa Deprimida; cartografía del riesgo de inundaciones; escorrentía; infiltración; precipitación; SCS-CN; sensores remotos;

   Abstract : The purpose of the thesis is to characterize flood events within the agricultural fields of flooding Pampa in Argentina. The characterization divides the flat landscape into flood prone areas and endeavour at linking driving factors to flood response based on past events. READ MORE

5. 4. Damage Assessment of the 2022 Tongatapu Tsunami : With Remote Sensing

   University essay from KTH/Geoinformatik

   Author : Milton Larsson; [2022]
   Keywords : remote sensing; land cover classification; Sentinel-1; Sentinel-2; change detection; change vector analysis;

   Abstract : The Island of Tongatapu, Tonga, was struck by a tsunami on January 15, 2022. Internet was cut off from the island, which made remote sensing a valuable tool for the assessment of damages. Through land cover classification, change vector analysis and log-ratio image differencing, damages caused by the tsunami were assessed remotely in this thesis. READ MORE

6. 5. Exploring Diversity of Spectral Data in Cloud Detection with Machine Learning Methods : Contribution of Near Infrared band in improving cloud detection in winter images

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

   Author : Nakita Sunil Oza; [2022]
   Keywords : Remote sensing; Multispectral imaging; Cloud detection; Data diversity; Deep learning; Fjärranalys; Multispektral bildbehandling; Molndetektion; Datadiversitet; Djupinlärning;

   Abstract : Cloud detection on satellite imagery is an essential pre-processing step for several remote sensing applications. In general, machine learning based methods for cloud detection perform well, especially the ones based on deep learning as they consider both spatial and spectral features of the input image.
