“Rezatec has successfully worked with Defra’s Plant Health team to generate a better understanding of how Earth Observation technology can be used to address the challenges posed by tree pests and diseases. Their ability to map a range of tree species ( incl. Ash, Oak and Sweet Chestnut) at remarkably high-levels of accuracy has supported our response to outbreaks and could potentially revolutionise Defra’s response to quarantine pests and diseases in the wider environment.”
