Step 1: RMS Amplitude fundamentals.
The opposite panel gives an overview of the attribute characteristics.

Step 2: Before attribute computation - Reflected amplitudes.
Discussion only focuses on signal processing matters. Neither Interpretation nor geological concepts are developed. However, to deal with concrete matters, example of acquisition footprint detection has been taken.
The reflected amplitude 620-ms time slice is extracted from post-stack time migrated 3D seismic data (Netherlands, F3 Block). Seismic volume covers 350 sq.km. No obvious evidence of amplitude footprint occurrence could be detected.

Step 3: With the RMS Amplitude attribute.
The E-W direction of seismic acquisition could be guessed by parallel stripes occurrence on the 620-ms time slice, only visible with the RMS amplitude. That phenomenon corresponds to the acquisition footprint.
