    Author : Yu Zhao; Yifang Ban; Andrea Nascetti; Josephine Sullivan; Cartalis Constantinos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wildfire; Remote Sensing; Active Fire Detection; GOES-R ABI; Suomi-NPP VIIRS; Image Segmentation; Deep Learning; Gated Recurrent Units GRU ; Transformer.; Vilda Bränder; Fjärranalys; Aktiv Branddetektering; GOES- R ABI; Suomi-NPP VIIRS; Bildsegmentering; Djupinlärning; Gated Recurrent Units GRU ; Transformer; Geoinformatik; Geoinformatics;

    Abstract : In recent years, climate change and human activities have caused increas- ing numbers of wildfires. Earth observation data with various spatial and temporal resolutions have shown great potential in detecting and monitoring wildfires. READ MORE

  4. 22. Water Quality and Optical Properties of Swedish Lakes and Coastal Waters in Relation to Remote Sensing

    Author : Niklas Strömbeck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; water quality; inherent optical properties; remote sensing; bio-optical models; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

    Abstract : Semi-analytical models for remote sensing of water quality parameters need to be parameterized with specific inherent optical properties. In this thesis, data on specific inherent optical properties of Swedish lakes and coastal waters is presented. Also, the problems of measuring in situ spectral backscattering are addressed.

  5. 23. Classification of Sweden’s forest and alpine vegetation using optical satellite and inventory data

    Author : Heather Reese; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Creation of accurate vegetation maps from optical satellite data requires use of reference data to aid in interpretation or to verify map results. Reference data may be taken, for example, from field visits, aerial photo-interpretation, or ground-based inventories. READ MORE

  6. 24. Integrated Optical Solutions for Ubiquitous Sensing

    Author : Stephen Macken; Daniel Filippini; Udo Weimer; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Ubiquitous chemical sensing aims at exploiting consumer electronic devices as temporary chemical sensing platforms. These devices are a highly disseminated infrastructure, not presently being exploited for chemical sensing purposes. READ MORE

  7. 25. Laser spectroscopic analysis of atmospheric gases in scattering media

    Author : Mikael Sjöholm; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fjärranalys; Remote sensing; Laser spectroscop; Scattering of light; Diode lasers; acoustics; optics; Electromagnetism; optik; akustik; Elektromagnetism; Optical absorption; Nondestructive testing: optical; Interdisciplinary applications of physics; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; LIDAR remote sensing; Laserteknik;

    Abstract : Laser spectroscopic techniques for gas analysis under various influences of light scattering are explored in a wide spectral range from the ultraviolet to the infrared. The techniques rely on spectrally narrow-band light sources that are used in differential optical absorption measurements. READ MORE
