Drones are most commonly used in the environmental and agronomic sectors to calculate NDVI maps. As a matter of fact, such tools reduce the cost of producing a single map in comparison to satellite products and allow its repetition during entire study periods.
To date we can calculate the following map types:
- GreenNDVI and RedNDVI maps for biomass concentration and photosynthetic activity assessment;
- MSAVI maps, i.e. an evolution of NDVI maps, for crops whose development does not generally cover the whole field;
- Segmentation maps to identify the percentage of land cover or the spreading percentage for a specific crop type;
- Phytotoxic effect assessment;
- Vigour assessment.
