Question

The correlation coefficient between two bands of remote sensing data that would yield good classification is

• A. close to one
• B. close to zero
• C. close to ten
• D. between one to ten

Hint:

A correlation coefficient close to one indicates a strong positive relationship between the bands, which is ideal for classification.

Answer 1

The Correct Option is B

The correlation coefficient measures the strength and direction of the linear relationship between two bands of remote sensing data. A value close to one indicates a strong positive linear relationship between the bands, which typically results in better classification. In remote sensing, a higher correlation between the bands generally means they are similar in terms of the spectral characteristics they measure, which can help in classification tasks. Step 1: Analyzing the options. - Option (A) is correct because a correlation coefficient close to one indicates a high positive correlation, which is beneficial for classification. - Option (B) is incorrect because a correlation coefficient close to zero means no correlation, which is not useful for classification. - Option (C) is incorrect because the correlation coefficient cannot be close to ten; it is bounded between -1 and 1. - Option (D) is incorrect because the correlation coefficient is between -1 and 1, not between 1 and 10. Thus, the correct answer is (A).
