During multispectral measurement, the measuring camera mounted on the drone captures images of a given area across multiple wavelengths – for example, in the visible and infrared ranges. Since surface materials, plants, soil, or water reflect different wavelengths of light differently, the camera collects data in multiple bands simultaneously and stores them as separate image layers.
The data recorded in this way is later processed, and various indices are derived. These indices provide information about vegetation health, soil moisture, or other environmental factors.
Application areas:
- Environmental monitoring and management
- Urban planning and infrastructure development
- Agricultural surveys
- Archaeology and cultural heritage
- Land and property management
- Forest and wildlife management
Advantages:
- High-resolution examination of the surface without the need for direct physical contact with the area.
- Effective for surveying large areas
- Early detection of problems (e.g., nutrient deficiencies, plant diseases)
