Agri-tech has undergone tremendous improvements with the introduction of remote sensing technologies, making many agricultural properties that were difficult to achieve before now accessible.

Multi-Spectral imaging has been widely used on satellites (e.g. Landsat) for earth observation science at a global scale. In the agricultural domain, UAVs as a platform have played a major role utilising various payload sensors including multi-spectral imaging.

The advantage of multi-spectral imaging is that it extends human sight sensitivity beyond the visible spectrum. Some wavelengths that are widely recognised for applications, such as the normalised difference vegetative index (NDVI), can be deployed into multi-spectral imaging. Nonetheless, it has been proved to be very useful in many other fields, greatly empowering the advancement of agriculture. The adoption of UAVs has made it possible to achieve large-scale mapping and thus better agricultural management.

Agri-EPI Centre has invested in the Multi-spectral VTOL UAV which has a potential use as ground truth technology for other technologies and/or systems.

This UAV and sensing payload system can also be used for a variety of fruit orchard use-cases which include:
• Estimation of leaf area index
• Estimation of canopy volume
• Estimation of water stress
• Fruit biomass estimation
• Temperature variation across the orchard
• Temperature variation of specific plants over time
• Fruit count estimation

It can also be used in other agricultural areas which include:
• Pest infestation detection
• Quantity moisture levels
• Analyse wildlife damage
• Vegetation index creation like NDVI
• Crop counting
• Create 3D photogrammetry maps
