In-Class Exercise 5
Part 2. Compute covariance and correlation matricesQuestions:
Band 1 2 3 4 5 6 7 Mean Standard deviation Variance Minimum Maximum Range 1. Which band has lowest BV? Highest BV? Which band exhibits the greatest range in BV? Explain physical importance of these band differences?
2. Which band exhibits the smallest variance and standard deviation?
Example Covariance and Correlation Matrix from Landsat TM 6 band image of Delmarva Peninsula3. Which bands are highly correlated? What does this suggest about the bands that are highly correlated?
4. Which bands have low correlation? Explain why these bands are uncorrelated?
