Technology
Inside Irrisat®
Satellites, weather
and agronomic models.
The need for water changes with the development of the crop and with the weather. IRISAT® integrates this information to read irrigation in space and time.
✔ Sentinel-2 images, weather data and FAO 56 method.
An integrated approach
Four components, one result.
01
Earth observation
Satellite images describe crop development and differences between plots.
02
Weather data
Rain, temperature and other variables describe the evaporative demand, even in the following days.
03
Agronomic modeling
Methods based on the FAO approach 56 estimate evapotranspiration and irrigation needs.
04
Web platforms
Maps, time series and irrigation tips reach users via web platforms.

The satellite
Sentinel-2, eyes on your fields.
Among the images that Irrisat® uses are those of satellites Sentinel-2 of the European program Copernicus: they photograph the territory even in wavelengths invisible to the human eye, those that tell the state of the vegetation.
- 13 spectral bands, from the visible to the infrared
- Detail up to 10 meters
- Images 290 km wide
- A new step every 5 days
One technology, two scales
From the single camp to the entire area.
The basis remains the same: the integration between observations, models and territorial information.
For farms
The irrigation advice.
Information to better manage irrigation, plot by plot.
- crop needs
- Forecast
for consortia
reading the area.
Irrigated areas, estimated needs and volumes over the entire territory served.
- irrigated area maps
- Estimation of irrigation volumes
The method
FAO approach 56.
The calculation of irrigation needs follows the method described in the FAO publication “Crop Evapotranspiration” (irrigation and drainage paper 56). The estimate of irrigation needs complies with what is reported in Ministerial Decree 31.07.2015.
Your questions
read the data carefully
No. The images describe the culture at the available acquisition dates; Weather data feeds the calculation of day-to-day needs.
It is modeling information, to be read with respect to the period, the scale and the available data, and to be compared with the measures and conditions of the field.
Location of plots, crops, irrigation and measures, where available, complete the satellite reading.
