What we do

Derive satellite-based information for crop-specific monitoring

The process

GeoWatch Labs convolutes multiple layers of information, comprising of satellite imageries, remote sensing climatic variables, crop-specific characteristics and local farming practices to take into account all parameters influencing yields.

Collection of data

Satellite imageries and remotely-sensed climatic data are collected for the studied area, ensuring the scalability of the monitoring system as well as spatial and temporal homogeneity regarding input data.

Crop type classification

A first step is to identify agricultural fields in order to filter satellite signals only to cultivated lands. Crop classification comes next in order to adapt growth modelling to the plants' characteristics.

Crop growth modelling

Crop growth modelling requires various layers of information to be taken into account to reproduce the local environment of the plant. Climatic data and satellite imageries are combined based on agronomic considerations to monitor the plant growth on a daily basis.

Yield forecast and final estimation

Monitoring the growth of the plants enables GeoWatch Labs to forecast the expected yield learning from the local historical agricultural seasons. Final estimations of yields are rendered once the harvest has been detected.
