Q. Why does LANDFIRE use VDDT?

Although other quantitative state-and-transition models exist, VDDT (Beukema and others 2003) was selected as the model of choice for nationally consistent fire and fuel projects because it is:

public domain, free and accessible to all (www.essa.com/vddt)
user-friendly
non-spatial, not affected by lack of spatial data or data storage requirements
