Using remote sensing technologies to supervise the growth and nutrition status of crops is the primary research content of precision agricultural management. Leaf nitrogen content is central to understanding plant and whole agricultural ecosystem function, but so are other leaf properties, especially water content, pigments such as chlorophylls. Numerous(More)
A novel approach, termed Summed Positive Peaks (SPP), is proposed for determining phytoplankton abundances (Chlorophyll-a or Chl-a) and surface phytoplankton bloom extent in the optically complex Baltic Sea. The SPP approach is established on the basis of a baseline subtraction method using Rayleigh corrected top-of-atmosphere data from the Medium(More)
Laser remote sensing has been widely applied during the last decade, it has great advantages in objects observation remote sensing. The different applications of lidar provide unique data on 3 dimensional topography survey, canopy geometry and etc. However, most of the lidar applications are concentrated on the detection of vertical spatial information, but(More)
