Model, Observations & Parameters
In this page, presentations are about Arecaceae's architecture, growth and development observations and modelling.
Each PRINCIPES model's parameters that are used to model 3D palm-tree architecture are introduced, illustrated, and operating procedure to make observations are detailed. Vegetative and reproductive parts of palm-tree are presented into 2 separated présentations.
For each parameter of PRINCIPES model, we detail :
- Model assumptions
- Parameters values
- Observations and measurements to collect
- Variables to compute.
Observations, measurements and Field Forms to collect data
Field forms are provided in english and french language in order to collect vegetative observations on palm-trees and put them directly in PRINCIPES parameter files providing default modelling.
See PRINCIPES parameterfiles Download in PRINCIPES for parameter files based on your own observations.
Forms for Vegetative organs.
PRINCIPES model
Carl von Linnaeus named palm-trees “PRINCIPES” (the princes of trees).
- Thats's why we named architecture's palm-trees model “PRINCIPES”;
- PRINCIPES is featured (we hope) for every arecaceaes architecture;
- This presentation explain the bases of PRINCIPES model;
- Typology, growth and development, features and observations are detailed to construct the model;
- Scales, topology, branching, succession, explain how we can build a 3D palm-tree representation;
- Assumptions of the model and main uses are finally shortly presented as introduction to next presentations.
