Graphical user interface for wildfire simulation service

Wildfire simulation service is based on DEVS

wildfire simulation service at

provide a web-based GUI for its end users in the front end.

and researchers can:

create a simulation service instance;

reset the simulation service;

destroy a simulation

choose a project to do the simulation

set ignitions or fire lines

set suppressions or suppression lines

start the simulation;

pause the simulation;

stop the simulation;
