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

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?
