Aratos Earth Observation Data Platform supports a new map layer for Environmental and Crop Research.



In the renewed system of Aratos Earth Observation Data Platform the renewal of the Leaf Area Index (LAI) layer is added. The LAI is defined as half the total area of green elements of the canopy per unit horizontal ground area.

The Leaf Area Index is thus an important indicator of radiation and precipitation interception, energy conversion, and water balance. Ultimately, it is a reliable parameter for plant growth. This is the reason why most studies in agronomy and horticulture measure the results of interventions such as fertilizers and irrigation in terms of LAI, as well as yield. Also, the levels of LAI will vary with the canopy architecture, which depends on the cultivars, geography, and field cultural practices. Then there are differences which arise from the types of crops and fruits.
