  3. 12. Estimation of canopy structure and individual trees from laser scanning data

    Författare :Eva Lindberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : During the last fifteen years, laser scanning has emerged as a data source for forest inventory. Airborne laser scanning (ALS) provides 3D data, which may be used in an automated analysis chain to estimate vegetation properties for large areas. LÄS MER

  4. 13. Carbon Dioxide and Water Vapour Exchange within a Norway Spruce Canopy

    Författare :Lasse Tarvainen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen allocation; optimality; stomatal conductance; photosynthesis; resource use efficiency; stem respiration; conifer;

    Sammanfattning : Terrestrial ecosystems can act both as sinks and sources in the global carbon cycle. Forests are an important part of this system and a good understanding of their carbon balance is essential for assessments of the future climate and for evaluating mitigation strategies. LÄS MER

  5. 14. Revealing the role of shredders and detritus in open-canopy, intermittent streams

    Författare :Karolina Leberfinger; Jan Herrmann; Manuel A.S. Graça; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Freshwater ecology; Limnisk ekologi; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Many streams run through naturally-unforested, agricultural, and residential landscapes and thus do not have closed riparian canopies. Little is known of food web dynamics and ecosystem function in such open-canopy streams. LÄS MER

  7. 15. Segmentation of forest patches and estimation of canopy cover using 3D information from stereo photogrammetry

    Författare :Ann-Helen Granholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 3D information extracted by image matching of aerial images, so called image-based point clouds, have been found to provide accurate vegetation height measurements. This has led to an increased interest from the vegetation mapping community, since aerial images are an affordable alternative to airborne laser scanner (ALS) data. LÄS MER
