HYSWEEP® is an optional module that provides for the calibration, data collection and data processing of multibeam sonar data inside the HYPACK® package. HYSWEEP® has been integrated to almost all multibeam systems, including those from Odom, Reson, Konigsberg/Simrad, Elac/Seabeam, and GeoAcoustics. With over 500 HYSWEEP® users on six continents, HYSWEEP® has proven to be powerful, cost effect and easy to learn.

Although software packages provided by multibeam manufacturers might be great at data collection, they are usually weak when it comes to generating final products. What’s great about HYSWEEP® is that it is fully integrated into HYPACK®, allowing you access to all of the great final product routines, including volume computations using your multibeam data.

System Calibration

One of the most important aspects of multibeam surveying is to establish the exact mounting angles of your multibeam sonar. HYSWEEP® allows you to quickly determine the exact roll, pitch and yaw angle offsets of your system, along with the precise time delay between your positioning system and the multibeam system. The ‘PATCH TEST’ is a standard feature of the MBMAX Multibeam Editing Program.

By running a series of short survey lines, the multibeam surveyor can quickly load the data through MBMAX to determine the mounting angle offsets, or to verify existing offsets. Calibrating your system, which used to take days, can now be done in a few hours.


The HYSWEEP® SURVEY program provides graphical feedback to the system operator while accurately time tagging and logging all of your multibeam data.

Waterfall displays of the multibeam scans and the pseudo-sidescan (if available) allow for real time targeting of objects. The coverage map provides a real time coverage display where the operator can ensure that they have either 100% or 200% coverage of the survey area. Coverage information can be painted in either HYPACK® SURVEY or HYSWEEP® SURVEY.

A new addition to HYSWEEP® SURVEYS Quality Assurance displays is the real time TPE (Total Propagated Error) windows for depth, position and maximum target detection size. The coverage map can be set up to only draw coverage where the TPE has met IHO or USACE quality standards. The new TPE EDITOR can be used as a planning tool to see if your survey system meets IHO Special Order, IHO Order 1, USACE Soft or USACE Hard Bottom requirements.


The multibeam editor of HYSWEEP® is called MBMAX. MBMAX time correlates all of the associated data records and computes refraction corrections to determine the actual touch-down point of each beam. In Stage 1, the user can review the navigation tracklines, heave-pitch-roll, tide-and-draft and sound velocity profile information. Navigation tracks can be edited, “True Heave” can be applied (from POS/MV and F-180 systems), corrections can be applied to eliminate heave drift, tides can be re-computed using RTK TIDES.

Stage 2 is our swath-by-swath editing. The user can examine the precise bottom detail using our OpenGL displays. Automated geometric filters can be applied to eliminate outliers.

Stage 3 is our area-based editing. Points are grouped into ‘cells’ and statistical filters can be applied based on the distribution of z-values in each cell. Vegetation filters can be applied to eliminate weeds.

At any time, the user can save to our HS2 format. HS2 contains all of the work (up to this point) and is accepted by many of HYPACK®’s post processing and final product routines. The nice thing about HS2 is that the user can load it back into MBMAX and resume their editing session or undo previous edits. Users can also save to XYZ (with several options) and to GSF for loading backscatter and snippet data into GEOCODER™.

Post-Processing in Cube

CUBE™ is a standard part of HYPACK®. No additional amount will be invoiced for CUBE™ when Hysweep is purchased.
CUBE was developed by Dr. Brian Calder of UNH-CCOM and has been licensed to HYPACK as a standard feature of our HYSWEEP® module. CUBE provides for near-automated editing of multibeam data, allowing for rapid turn-around of your data.

CUBE generates a gridded pattern of XYZ depth estimates that accurately represents your actual survey data. The user can also save real-world XYZ data points that mirror the CUBE surface.

One of the great features of CUBE is the ability to generate an uncertainty surface. This provides the surveyor with a great Q/A presentation tool.

Post Processing in CLOUD

CLOUD™ is a standard part of HYPACK®. No additional amount will be invoiced for CLOUD™ when Hysweep is purchased.
HYPACK®’s CLOUD program is our Point Cloud Editor. It allows for the import of ASCII XYZ or HYSWEEP®’s HS2 data files. Users can then manipulate the files inside an OpenGL environment where they can review the data and edit outliers. CLOUD can create some stunning images of your data.

Post Processing in GeoCoder

GEOCODER™ is a standard part of HYPACK®. No additional amount will be invoiced for GEOCODER™ when Hysweep is purchased. One of the great features of GEOCODER™ is its ability create mosaics from either average backscatter or snippet data. HYSWEEP® SURVEY stores the average backscatter data (if available) and snippet data from certain systems. The user can edit the data files in MBMAX and then export the combined geometry and ABS/Snippet data to GSF format files.

The primary benefit of mosaics made from ABS/Snippets is that the positioning of objects is exact, whereas with side scan data there are small errors present due to assumptions made about the bottom.

GEOCODER™ developed by Dr. Luciano Fonseca of UNH-CCOM and licensed as a standard feature in HYPACK®, can import the GSF files and then generate mosaics. Those mosaics can be saved as TIFs and displayed throughout HYPACK®.

Another exciting feature of GEOCODER™ is its ability to apply Angular Range Analysis to make estimates of the bottom type.
