Multispectral Mapping

What is Multispectral Mapping?

Multispectral mapping quite simply is the use of multispectral sensors to map and area, including sensors that detect non-visible light. It has many use cases, but we use our sensors for precision agriculture.

The sensor detects the following bands in the electromagnetic spectrum; Blue (475 nm center, 32 nm bandwidth), green (560 nm center, 27 nm bandwidth), red (668 nm center, 16 nm bandwidth), red edge (717 nm center, 12 nm bandwidth), near-IR (842 nm center, 57 nm bandwidth)




Some of the benefits of Multispectral data

  • Identify pests, disease and weeds. 
  • Optimise pesticide usage and crop sprays through detection and monitoring
  • Reduce costs by spraying the areas that require spraying
  • Detecting nutrient deficiencies
  • Help with land management and crop rotation. Develop policies based on real-time data.
  • Count plants and determine population or spacing issues.
  • Estimate crop yield.
  • Measure irrigation. Control crop irrigation by identifying areas where water stress is suspected. 
  • Improved drainage based on the multispectral data.
  • View damage to crops from farm machinery and make necessary repairs or replace problematic machinery.


How is multispectral mapping different?

The sensor we use, is the industry leading Micasense Altum, which is mounted on one of our DJI M300’s. The drone is big enough to carry the weight of the sensor and provides long flight times as multispectral mapping requires high overlap and due to the smaller size of the sensors compared to a high-resolution RGB for example, needs to be flown lower. This increases the survey time and requires we have sufficient batteries to complete. We use the leading control station software, UGCS to ensure we have consistent ground sampling distance due to its terrain following features. As the terrain rises and falls, the drone follows to provide the best quality data. 

We have completed hundreds of multispectral missions, both capturing data and processing the outputs to provide you with the results you need. We price our jobs based on the location and size of the area so get in touch today to benefit from the best quality data for precision agriculture.
