Hypack Software was utilized for both real-time data acquisition and post-acquisition processing. During the acquisition phase, pulse interval, power, and gain parameters were meticulously adjusted in response to varying depth conditions and site characteristics. These dynamic adjustments ensured optimal data quality capture, adhering to project standards. ESRI’s 3D Analyst toolset was used to derive point files to build Triangulated Irregular Network (TIN) and consequently contours. Data processing included the following steps: ASCII to Feature Class, Feature class Z to ASCII, .txt file, XY table to Point, Point (.shp) to TIN, and TIN to Surface Contour.
Point data was gathered in 3 sets for all 6 subdivisions, High Frequency (HF), Low Frequency (LF), and Difference between HF and LF (Diff/HF-LF/Diff_elev/Diff_T [difference for transverse profile/Diff_L Difference for Longitudinal Profile]) files for both longitudinal and transverse data profile lines.
