To provide extra functionality for our LF users, we are currently investigating an image service option to access LF data layers.

If you do not find the question you're looking for, please try the LF Helpdesk Dashboard for more questions from users and their resolutions.

Q.  In what units are LANDFIRE Canopy Base Height (CBH) and Canopy Bulk Density (CBD) measured?

Canopy base height is measured in units of meters * 10. Thus, a value of 5 on the CBH grid layer is actually 0.5 meters. Canopy Bulk Density is measured in units of Kg m-3 * 100. Thus, a value of 6 on the CBD grid layer is actually 0.06 Kg m-3. The multipliers augment the raw units to facilitate implantation in FARSITE and FlamMap. Full descriptions of the CBH and CBD products can be found in the Data Products: National section of this website.


Users may experience intermittent service Thursday evenings due to routine maintenance.
The LF Map Viewer (DDS) will be down every 3rd Wednesday from 8 am - 10:00 am (CDT) for routine maintenance.
