Software dedicated to the interpretation of seismic refraction surveys using the reciprocal method and the generalized reciprocal method (G.R.M.). Main features: •No limitation on the number of shots •Import of data from SEG2, SEGY, ST, dta, drm and text files •Geographical location of the investigation site •Application of textures or colors to the section obtained •Application of digital low pass filter with the possibility to choose the cutoff frequency and display the frequency analysis of traces •Automatic estimation of first arrivals using the Energy Ratio Method algorithm •Amplification of traces • Custom definition of the time travel curves •Automatic detection of slope change points •Export of results to *.DOC, *.DXF, *.BMP, *.JPG formats and to other GeoStru software applications
