| Research Abstract |
We developed a GIS-based mating modeling technique. Individual canopies were identified through airborne image segmentation, and CML was established with the segmanted 4073 canplies. The dynamics of the acorn production of each tree is modeled as an oscillator in the CML. Coupling in this CML corresponds to pollen coupling between trees. To determine the features of the developed spatiotemporal dynamics, we employed a spatial autocorrelation function and conducted a parameter study by changing fundamental system parameters such as coupling strength. The output of the model was expressed in a GIS base to enable easy visualization of the spatiotemporal dynamics and spatial synchrony. Additionally, this approach was able to show the difference between conventional CML model and our GIS based CML model. We also improved RBM by employing with whether cue.
