  3. 2. Testing the robustness of the Plant Phenology Index to changes in temperature

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Iain Lednor; [2015]
    Keywords : NDVI; Plant Phenology Index; physical geography and ecosystem analysis; remote sensing; EVI2; Vegetation Index; temperature; phenology.; Earth and Environmental Sciences;

    Abstract : Traditional vegetation indices have long encountered a problem of saturating at high biomass levels. A newly formulated vegetation index, the Plant Phenology Index (PPI), which has a near linear relationship with canopy green leaf area index (LAI) is tested in this study against temperature at 12 sites across Sweden.

  4. 3. Combining hyperspectral UAV and mulitspectral FORMOSAT-2 imagery for precision agriculture applications

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Caroline Gevaert; [2014]
    Keywords : Physical Geography and Ecosystem analysis; GIS; precision agriculture; crop monitoring; data fusion; Earth and Environmental Sciences;

    Abstract : Precision agriculture requires detailed information regarding the crop status variability within a field. Remote sensing provides an efficient way to obtain such information through observing biophysical parameters, such as canopy nitrogen content, leaf coverage, and plant biomass. READ MORE

  5. 4. Plant Condition Measurement from Spectral Reflectance Data

    University essay from Bildbehandling

    Author : Peter Johansson; [2010]
    Keywords : Leaf reflectance spectrum; Plant condition; PCA; PLS; MLR; CCA; Multidimensional signal analysis;

    Abstract : The thesis presents an investigation of the potential of measuring plant condition from hyperspectral reflectance data. To do this, some linear methods for embedding the high dimensional hyperspectral data and to perform regression to a plant condition space have been compared. READ MORE
