Crop Monitoring

Use satellite imagery and remote sensing to estimate irrigation water consumption.

Efficiently manage water resources through geospatial data technologies

Irrigation is responsible for around two-thirds of worldwide freshwater use. The increasing pressure on water resources emphasises the need for the efficient and sustainable management of water supplies through planning processes and surveillance of agricultural water use.

At ADASA, our water experts have mastered the use of satellite imagery and remote sensing techniques to estimate the water consumption for growing crops.

Every project is different, and the most appropriate platforms and sensors are selected for each study, to provide suitable spatial and spectral resolutions. We collect a series of satellite scenes that optimises crop discrimination, then conduct fieldwork to reconfirm the quality assessment of our observations. From this extensive investigation, we then estimate the agricultural area’s water consumption while the irrigation season is taking place.

We achieve this through office-based checks on:

Radiometric corrections.
Signatures extraction and legend definition.
Vegetation index.
Crop coefficients.
Spectral classifications.
Combining complementary information in multi-criteria decision trees.
Assessments of evapotranspiration.
Water consumption of each crop.

Land use thematic cartographies are updated with this information (and related metadata), alongside related water resource statistics, with everything then integrated into spatial databases.

Our analysis methodology is adapted to the most pertinent crops in each study, including herbaceous and woody crops. The result is outstanding reliability achieved by diligence and competence.
