  1. 1. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

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

    Author : Ahmad Talaat Hifzy; [2023]
    Keywords : Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

    Abstract : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. READ MORE

  3. 2. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Nils Helge Havertz; [2023]
    Keywords : Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

    Abstract : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.

  4. 3. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

    University essay from Umeå universitet/Institutionen för fysik

    Author : Klara Lindroth; [2023]
    Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

    Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

  5. 4. GIS Processing on the Web

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Erik Knutsson; Manne Rydhe; [2022]
    Keywords : GIS; NodeJS; WebAssembly; Wasm; GDAL; JavaScript; SPA; GC; browsers; benchmark; memory; Ogr2Ogr;

    Abstract : Today more and more advanced and demanding applications are finding their way to the web. These are applications like video editing, games, and mathematical calculations. Up until a few years ago, JavaScript was the only language present on the web. That was until Mozilla, Google, Microsoft, and Apple decided to develop WebAssembly. READ MORE

  6. 5. ALS (Airborne Lidar) accuracy: Can potential low data quality of Lidar ground points be modelled/detected based on recorded point cloud characteristics? Case study of 2016 Lidar capture over Auckland, New Zealand

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Gabriela Olekszyk; [2022]
    Keywords : Geography; GIS; Lidar; ALS; Point cloud; Accuracy; Quality; Technology and Engineering;

    Abstract : Gabriela Olekszyk ALS (Airborne Lidar) accuracy: Can potential low data quality of Lidar ground points be modelled/detected based on recorded point cloud characteristics? Case study of 2016 Lidar capture over Auckland, New Zealand. Lidar (Light Detection and Ranging) data is becoming more widely available and accessible. READ MORE
