Spot spraying weeds with a drone map

Steps

1. Fly the field with an RGB or multispectral drone and load the images into PIX4Dfields. Processing runs on your laptop, without internet.
2. Set a grid over the orthomosaic or the index layer. Each grid cell becomes a decision: spray or do not spray.
3. Teach the Magic tool two labels: one for weed patches and one for clean crop. It classifies every cell of the field from those examples.
4. Review the map and correct any cell by hand.
5. Export the prescription as ISOXML, Shapefile, GeoJSON or KML, or send it to John Deere Operations Center. Pix4D lists compatibility with DJI, XAG, TopGun, EAVision and ABZ spray drones.

Where else the same method works

• Green on brown spot spraying before planting.
• Marking damaged areas for replanting.
• Quantifying wind lodging or hail damage for insurance claims.
