1. Oceanic Imaging Consultants, Inc. Software • Services • Systems Professional seafloor mapping software, createdby surveyors, for surveyors 1144 10th Avenue, Suite 200 Honolulu, HI 96816-2442 (808) 539-3706 • info@oicinc.com

2. GeoDAS:Geophysical Data Acquisition System

3. What is GeoDAS? • Geophysical Data Acquisition System Not the sonar… …but rather the survey system.

4. GeoDAS Development • Begun in 1994 • Purpose-built software for quantitative seafloor mapping • Designed for new breed of digital sonars: EdgeTech DF-1000, Ultra, etc. • POSIX-compliant, UNIX OS, C/C++ • Adapted by USN in 1995 • Ported to Windows in 1998

5. GeoDAS:Geophysical Data Acquisition System Data goes in, pictures come out • Data Input OIC Software Output Navigation Media Sidescan Printers Sub-Bottom Bathymetry Final Maps Magnetometry

6. GeoDAS Design Philosophy • Never lose data – 24/7/365 logging • Always log RAW data • Process data in real-time • Time-stamp to 1 ms • Geo-code (mosaic) in real-time • Built-in measurement, targeting, database, reporting, mission utilities

7. What can GeoDAS do for you? • Interface to sensor(s) • Log Raw Data & NAV • Enhance Imagery • Suppress Artifacts • Calculate altitude • Mark Targets • Show Coverage • Display Charts • Archive Data • Print Data

8. What ELSE can GeoDAS do for you? • Real-time integration of • Sensor navigation & attitude • with • Real-time processed sonar data • Means: • Real-time mosaicking

9. Supports Data Acquisition & Real-Time Processing from a Wide Range of Sensors: • Sidescan • All Benthos/Datasonics • All Edgetech • All Klein • Tritech • C-Max • Imagenex • Edo • SeaScan (Korea) • All MSTL • Any analog 2/4 channel

10. Supports Data Acquisition & Real-Time Processing from a Wide Range of Sensors: • Sidescan • Multi-beam • All RESON SeaBat • All SIMRAD EM series • Odom Echoscan • Seabeam/Elac • Atlas Hydrosweep

11. Supports Data Acquisition & Real-Time Processing from a Wide Range of Sensors: • Sidescan • Multi-beam • Interferometric • All SeaMARC Series • All Ultra Deepscan • RDI BSSS • TAMU-TAMU • Submetrix • AMS 50/60/120 • Benthos C3D (soon)

12. Supports Data Acquisition & Real-Time Processing from a Wide Range of Sensors: • Sidescan • Multi-beam • Interferometric • Optical • Raytheon Laser Linescan

13. Supports Data Acquisition & Real-Time Processing from a Wide Range of Sensors: • Sidescan • Multi-beam • Interferometric • Optical • Raytheon Laser Linescan • Electronic Still Cameras

14. Supports Data Acquisition & Real-Time Processing from a Wide Range of Sensors: • Sidescan • Multi-beam • Interferometric • Optical • Raytheon Laser Linescan • Electronic Still Cameras • “Streak LIDAR” • laser imaging plus • bathymetry!

15. After SAS Before SAS Additional Processing Options:SAS • GeoDAS for Synthetic Aperture Sonar, with DTI & Ultra (UK)

17. New GeoDAS Features: • Electronics Charts: DNC, S-57, BSB, ARCS

18. New GeoDAS Features: • Survey / way-point Layout (2-D)

19. New GeoDAS Features:SmartSonar • Issues: • Sensor complexity overwhelms operators • Too much to adjust: range, gain,pulse-width, etc • Operators may not be present (AUV) • how do we tune for unknown terrain? • Better raw data would give better input to ATAR • And give better raw data for survey • SAS makes ATAR mandatory • If we can detect in raw element data, may not even need SAS • Status: • CEROS (Centers of Excellence for Research in Ocean Sciences) (DARPA $$) funded development of automatic sonar tuning, and target recognition • Scheduled for release Fall of 2005

20. New GeoDAS Features: ROVer’s Eye Seabed visualization for Mission Planning / Execution ROVer’s Eye GUI, showing Klein5500 data over Reson 8101 bathymetry

21. An example of Survey Planning and Execution with GeoDAS and ROVer’s Eye

22. Mission Planning & Execution: Step 1: Select your region of interest • Point and Click on a location on one of several user selectable base maps

23. Mission Planning & ExecutionStep 2: Zoom in • Zoom in to map limits to refine selection

24. Mission Planning & ExecutionStep 3: Refine selection from chart • Charts, if available, are auto-loaded to help define area • (DNC, S-57, BSB, etc.)

25. Mission Planning & ExecutionStep 4: Name/Define Project • Supply a project name, description, sampling/logging requirements, and refine position/ROI

26. Step 5: Background bathymetry loaded in ROVer’s Eye: • Digital Bathymetric DataBase, Variable res. (DBDBV) included with GeoDAS, along with World Vector Shoreline data
