Parameterization and validation of a 3-dimensional simulation model of European beech (Fagus sylvatica L.), using the software tools XPlo and GroIMP


Description:


The software GroIMP is used as a tool for the development, evaluation and visualization of functional-structural plant models specified in the rule-based language XL (Kniemeyer 2008, Kurth 2007). A model of 3-d growth and development of young trees of European beech has been implemented with the GroIMP platform already by Kniemeyer (2008; pp. 317ff.).


GroIMP shall be embedded as one possible "growth engine" into the software platform XPlo, which was designed at the research unit AMAP (Montpellier, France; see Griffon & de Coligny 2012, 2013). A smooth embedding of GroIMP will enable the usage of advanced analysis tools, which are already available in XPlo, to evaluate the simulated beech trees, to compare them with real tree data and to optimize the parameterization of the model.


Both software systems, GroIMP and XPlo, are implemented in Java. This project thus requires some acquaintance with the Java programming language.


Preliminary work for linking the two platforms was already done by Y. Ong (unpublished), providing a basis for this project.
