Detection of Ground Materials Using Normalized Difference Indices with a Threshold: Risk and Ways to Improve

Detection of Ground Materials Using Normalized Difference Indices with a Threshold: Risk and Ways to Improve

In this short communication, we describe the shortcomings and pitfalls of a commonly used method to detect ground materials that relies on setting thresholds for normalized difference indices. We analyze this method critically and present some experimental results on the USGS and ECOSTRESS spectral...
