How to generate and analyze the NDVI of a Vineyard with the Drone for Precision Farming.

Do you want to monitor the health condition of your vineyard? Are you a professional who wants to provide the service for NDVI monitoring of a Vineyard or a Crop? Analist Group has the Complete Solution which is accessible to everyone for Precision Farming: Phantom MAPIR. The Complete Solution for Precision Farming Phantom MAPIR: real case application of survey and NDVI analysis of a Vineyard.

Procedure for data acquisition and NDVI map generation

  • Site analysis and flight planning;
  • Flight execution with automatic procedure and image acquisitioni;
  • Image processing with Pix4Dmapper to generate the orthomosaics and the NDVI;
  • NDVI analysis and interpretation;
  • Targeted intervention planning (pesticides, fertilizers,etc.).

Technical details:

The flight was carried out with a Phantom MAPIR by Analist Group equipped with MAPIR Visible Light RGB and  MAPIR Blu NDVI + NIR cameras.

  • Equipment used: Phantom MAPIR Solution with Visible Light RGB camera and MAPIR Blu NDVI + NIR camera
  • Flight height: 110m
  • Shooting sequence: 1 frame every 3 seconds
  • Flight time: 20 minutes
  • Speed: 10m/s
  • Surveyed area: about 8 hectares
  • Data obtained: Orthmosaic, NDVI Map

 

Results obtnained: Orthomosaic and NDVI

The Visible Light RGB Mapir camera mounted under the Phantom MAPIR allowed us to obtain an RGB set of photos which were then processed with Pix4Dmapper Photogrammetric Software thus generating the Orthomosaic of the vineyard as shown in Pic. 1.

The orthomosaic generated with Pix4Dmapper can be used for:

  • Grapevine counting;
  • Distances, areas and volume calculations;
  • Contour Lines;
  • Cross profiles and Sections, Areas and printing Layout with Analist 2016 CLOUD.

NDVI image from MAPIR Blu NDVI + NIR camera

To obtain the NDVI map and analyze the health condition of a grapevine we have used a MAPIR Blu NDVI + NIR and a MAPIR Visible Light RGB. The images processed provided a detailed map of the cultivation status.The NDVI map is essential in order to immediately understand which areas are healthy and where intervention is required.

How to accurately and correctly read the NDVI Map

The NDVI Map we obtained allows you to immediately assess the cultivation health condition. With reference to the NDVI index scale on the bottom left in Pic. 2 the pixels with a value which varies between -0.18 and -0.2 NDVI represent a non-vegetation state; the pixels listed with a value between +0.6 and +0.23 NDVI represent the vegetation and its health condition: the areas in a better condition are represented in RED; the less healthy are GREEN – YELLOW. The NDVI vegetation scale is: DARK BLUE-> BLUE -> GREEN -> YELLOW -> ORANGE -> RED. It is consequently immediately clear which areas need targeted intervention.

Conclusion

The real application case here shown, illustrates that with a 20 minute flight it is possible to obtain the NDVI Map of an approximately 8 hectar vineyard making it immediately possible to plan targeted interventions on the cultivation with considerable time and cost saving.
