Normalized Burn Ratio Calculator

Normalized Burn Ratio Calculator calculator can be used to assess the health of vegetation by comparing NIR and SWIR reflectance.

Input Parameters

Calculation Results

Calculation Formula

NBR = (NIR - SWIR) / (NIR + SWIR)

Where:
NIR = Near-Infrared reflectance
SWIR = Shortwave Infrared reflectance

Normalized Burn Ratio Calculator Calculator Usage Guide

Learn how to use the Normalized Burn Ratio Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the NIR (Near-Infrared) reflectance value in the percentage format (e.g., 30 for 30%).
  2. Enter the SWIR (Shortwave Infrared) reflectance value in the percentage format (e.g., 20 for 20%).
  3. Click the "Calculate" button to compute the Normalized Burn Ratio (NBR).
  4. The result will be displayed in the NBR field.

Understanding the Results

The NBR value ranges from negative to positive values. A higher NBR value generally indicates healthier vegetation, while a lower NBR value may indicate stress, damage, or burn areas.

Principle of NBR Calculation

The NBR index is calculated using the formula:

NBR = (NIR - SWIR) / (NIR + SWIR)

Where:

  • NIR = Near-Infrared reflectance
  • SWIR = Shortwave Infrared reflectance
