Back to the Fuel Manager home page.
Several creation modes for generating a 3D vegetation scene of the Fuel Manager are currently available throughout this user interface. Back to Quick Start Guide.
Select the option and click on GENERATE THE SCENE. The seed value is used to parametrize the stochasticity of the Fuel Manager. When 0 (default value) or a another positive number is chosen, it will be used as a seed to initialize pseudo random number for the run. If the same number is used on different architecture, but on the same version of the software, a same sequence of action will produce exactly the same data. These is a useful property for run and study replicability. When a negative number is chosen, random number sequences will always be different so that runs will always produce slightly different results. This mode is useful for sensitivity analysis of the fuel manager, but also of the fire model (if one is used).
This option is the most flexible. Several file examples can be found in capsis4/data/fireparadox/fromFieldParameters. The format definition is described below
Here below, polygon 1 is a square polygon of 50×50 m2.
|PolygonId||list of polygon summits|
Example given in file capsis4/data/fireparadox/fromFieldParameters/Mixed_stand_with_fire_effects.txt
Note: the “pattern sketcher” render for tree should be selected (with the option “by fire damage”) to visualized damage with the 3D Editor.

|Plant group number||species||polygonId||lDBH||uDBH||age||N||liveLMC||liveTMC||deadTMC|
Within a polygon as a function of stand parameters.
|Plant Group number||species||polygonId||hDom50||age||N||gHaET Factor||Gibbs||liveLMC||liveTMC||deadTMC|

A detailed inventory file can be loaded: it describes each vegetation object in details throughout its species, crown dimensions and location. It doesn’t require an access to the EUROFORESTFUELS database because it doesn’t contain vegetation object “ID” of the database.
This sub option is planned when user doesn’t need to run an export of the vegetation scene to be able to run the fire behaviour model. It enables to display on the vegetation scene a wider range of vegetation objects than those stored in the EUROFORESTFUELS database.
As example, an inventory file “Lamanon_Mixed.scene” is available in the given CAPSIS archive and precisely in the “capsis4_fireparadox\data\fireparadox” directory. The file describes 48 trees.
This sub option is not available yet. It will be necessary when user will finally need to create an export of the vegetation scene to be able to run the fire behaviour model. As the inventory file doesn’t contain vegetation object “ID” of the EUROFORESTFUELS database, the loading procedure will match each vegetation object with the most similar object present in the database.
An empty scene can be generated by giving the dimensions of the terrain.
CAPSIS can save scene in a special format that can be re open later for further modifications.
====FROM SVS MODEL====
Not operational, see Standfire.
====FROM A DATABASE INVENTORY====
This option enables to generate a vegetation scene by loading an inventory file which contains only vegetation objects known in the EUROFORESTFUELS database. The inventory file describes each vegetation object throughout its “ID” in the EUROFORESTFUELS database, and location. This option requires a connection with the remote database since species, height and crown dimensions are read for each fuel in the database before generating the scene. The inventory file contains also a line describing the dimensions of the terrain. Using this option to generate a vegetation scene will make possible the creation of export files necessary to run the fire propagation model.
As example, an inventory file “dataBaseFile_fc.scene” is available in the given CAPSIS archive and precisely in the “capsis4_fireparadox\data\fireparadox” directory. The file describes 48 trees.
