The sub-bottom profiling data can be trimmed to a border file which is very useful if one is only interested in viewing and interpreting a section of the dataset. Once the data files have been loaded, the sub-bottom profiling data is displayed in the Sub-Bottom Processing window and the navigation data in the View Tracks window the Settings window is used for the application of data processing parameters (Figure 3).
In HYPACK MAX (SBMAX) one can edit the navigation in a RAW file for “spikes” and apply the corrected EDT navigation to the sub-bottom profiling data. HYPACK SUB-BOTTOM can read navigation from the SEG-Y (or JSF) file, RAW file or EDT file (Figure 2). The program stores the project data file lists and user defined processing parameters in XML and Configuration files which makes it easier when re-opening the project again. HYPACK SUB-BOTTOM has the ability to load large sub-bottom profiling datasets in SEG-Y or JSF formats. In addition to this, a sophisticated triggering system enables simultaneous acquisition of two different SBP systems with no acoustic interference between the systems (Figure 1).
HYPACK ONLINE NAV SCREEN DRIVERS
The program has drivers to acquire data from any analog sub-bottom profiler (using a National Instruments digital acquisition card) or digital sub-bottom profiling data from the industry’s leading manufacturers.
HYPACK SUB-BOTTOM supports data acquisition in most coordinate systems using HYPACK’s comprehensive Geodesy library.
