The article aims to study the effect of layer thickness and reflection coefficient variation on the image of synthetic seismogram, which is generated by using Ricker Wavelet with wide range of frequencies (20-130Hz) and Vibrator Sweeps with many frequencies ranges (5-170Hz) as a known technique in reflection seismic method on land. The Researcher tried to determine the relationship between signals recording times and reflection coefficients variation from first side, and recording times with layer thickness variation from second side. The result which is observed that; the recorded times increased proportionally with increasing of the layer thickness (as we know), but it is delayed with exponential relation when the velocity and density are varied within the same layer. New manner is applied to represent the result by using the conversion of time seismic section to raster images by using GIS, this way gave us ability to control the colored scale which reflects the amplitude of recorded signals, and follows the reflectors or get important information about signals amplitude even though the layer thickness is decreased less than wavelet length ten times if we used Ricker signal or Vibration Sweeps.
