Research Interests:
  • Precision irrigation – Identifying variability in plants’ water needs  and optimizing irrigation water use in field crops and orchards using remote sensing
  • Early detection and prevention of soil diseases, reducing pesticide use and raising field crops yield
  • Precision spraying – applying spray to each tree in the orchard according to its canopy
  • Use of remote sensing tools to assess the number of wintering Gray Cranes and their impact on agriculture in the Hula Valley, Israel
  • Improving pests control strategies (emphasis on the carob moth) by agrotechnic and friendly methods in almond orchards using deep learning
  • Using deep computational learning to identify plant stress (water, diseases) from remotely sensed images at various resolutions.
  • Examining fresh water bodies' quality parameters via remote sensing

Remote sensing is defined as any information that can be collected on an object without physically touching it. Specifically, at the Agro-GeoInformatics lab, we use sensors that are sensitive to the sun's electromagnetic radiation spectrum, which is returned from objects (vegetation, water, soil, etc.) and from analyzing the objects’ spectral signature reflectance, we learn about plant health, soil and water status. The projects at the Agro-GeoInformatics lab focus on tracking changes in plant signals as a result of various stresses (irrigation, fertilization, pests or disease), in the visible, near and thermal infrared range of the electromagnetic radiation spectrum, using airborne sensors and satellites. We integrate image analysis and image processing, artificial intelligence, geo-spatial modelling, and GIS technology in order to solve interesting and difficult questions!
