Spectral signature
Vultus technology is centered around spectral and image analysis from remotely sensed data. Everything from plants to vehicles have unique spectral signatures that can be measured and quantified. Our unique insights into plant spectrometry allows us to quantify both plant health and nitrogen to give proprietary insight to farmers. The spectral signature is dependent on crop and climatic zones, the following curves show the generic trends.

Vultus Nitrogen Index
Based on years of research, 20 years of historic spectral data and extensive field replications, we built the Vultus Nitrogen Index, that is optimized for nitrogen distribution. It is a common misconception that normal plant health information can be used for nitrogen distribution. Although a correlation exists, it is incredibly weak and you face huge risk of misapplication, as illustrated.

API Integration
Our analysis is exclusively available through our API. The system is built for high performance, high volumes of data and easy integration. Formats and data structures follow open source standards, specifically JSON. For more information about integration, contact us.

Our processing pipeline
Although largely proprietary and highly complex, our processing pipeline follows an intuitive logic. First, we receive requests through our API, this initiates data fetching and processing. The fetched data goes through a pre-process including our self developed cloud masking and removal algorithms. Then, geometric, radiometric and atmospheric calibration takes place, which ensures high quality and ability to compare data over time. Following comprehensive calibration, we apply models to the data, either the a nitrogen calculation based on our Vultus Nitrogen Index, or plant health analysis following NDVI among other available plant health indices. The final data is reformatted and sent back through the API. The farmer can then view, analyze and implement the analysis.
