====== 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 [[soft:principes:start|PRINCIPES]] for parameter files based on your own observations.

===== PRINCIPES model =====

  * 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.
