Remote sensing pipeline

The remote sensing pipeline invented by VULTUS can process multiple types of high-resolution satellite data to obtain insights into numerous spectrally observable parameters. The pipeline is currently going through lab validation, where initial prototypes of synthetic aperture radar and optical observation for moisture and biomass measurements are being compared with in-situ measurements from open trial datasets.

Through the project, VULTUS aims to validate the outputs in the case studies, and demonstrate their usefulness in the framework both in a limited case study as well as on an operational basis. The pipeline will operate in the short-wave infrared spectrum to measure soil moisture and vegetation water stress, and uses a combination of visible near-infrared light and radar observations to measure vegetation densities and phenological stages (where possible). These measurements will also be used to calibrate the WVSI-WRC model. This will help WATERAGRI to decide upon and characterise the variation of the model parameters, which will be integrated in the database of the framework.

The soil moisture and vegetation water stress data will be integrated into the cloud and can be used to inform the real-time models for short-term predictions. The use of dense sub-weekly time series of multispectral imagery satellites (3-10m spatial resolution) from both the Copernicus Programme and private actors makes the monitoring of crop biophysical parameters feasible.
