NBR activity
Welcome to my teaching demonstration!
Here are some quick NBR facts:
NBR = (NIR-SWIR) / (NIR+SWIR)
NBR ranges from -1 to 1
High NBR = healthy vegetation (closer to 1)
Low NBR = burned or disturbed vegetation (closer to 0 or slightly below)
dNBR facts:
We can quantify disturbance by measuring the change in NBR values (dNBR)
dNBR = prefire NBR - postfire NBR
dNBR > 0: disturbance signal
dNBR < 0: increased healthy vegetation
dNBR = 0: no change
See lecture slides if you need to refer back to the course material
Questions to consider when exploring this dataset:
Where do you think the fire was?
Can you identify areas with high, moderate, and low burn severity?
What type of fire (surface, crown, ground) may have occurred in each area?
Is there anything else you noticed on the landscape?
