Remote Sensing for Precision Agriculture and Weed Science

Departament of Crop Protection
Major research lines of “Remote Sensing for Precision Agriculture and Weed Science” Group are centered on the optimization of agrochemical applications by using site-specific strategies.

Main current research activities are focused on the following objectives:

  • To detect and map weeds and other agronomic variables in herbaceous and woody crops by using remote sensing techniques and imagery from high resolution satellite and unmanned aerial vehicles (UAV).
  • To design, develop and evaluate OBIA (Objects-Based-Image-Analysis) procedures for geospatial analysis, image feature extraction, segmentation, tree geometry and vegetation classification in crops using digital cameras and multispectral sensors.
  • To improve the workflows for image processing by developing Geostatistics algorithms and specific software “add-on”- “plug-in” for precision agriculture approaches as well as for an accurate georeferenciation / co-registration and classification of cropping systems.
