Oil-palm digital twins from field measurements​#

Project: JPCE — Joint PT-SMART CIRAD Experiment · CIRAD and PT SMART, Indonesia.

Repeated measurements can turn a growing palm into a sequence of 3D scenes. In JPCE, this approach links the evolving architecture of individual oil palms with their light environment and whole-plant carbon and water exchange.

From the measured palm to individual leaflets​#

Architectural monitoring follows leaf emergence, dimensions, angles, and leaflet states through time. These observations drive dynamic reconstructions with explicit leaflets, giving the light model a geometry tied to the measured plant at each date.

ArchimedLight supplies the radiative environment for a workflow that couples light with biophysical models at leaflet scale. Whole-plant gas-exchange chambers on the target palms provide integrated carbon and water flux observations. The scientific objective is to test how well the structure and processes represented at leaflet scale explain those whole-plant observations.

The figure shows reconstructed architecture from this ongoing experimental workflow. Quantitative evaluation of the coupled light and physiological models is a separate step from producing the geometries.

This application comes from the joint CIRAD–PT SMART experiment in Indonesia. The illustrated reconstructions are outputs of the ongoing experimental workflow.
