What is GeoDAS?
Geophysical Data Acquisition System
Not the sonar…
But rather the survey system
March 2005GeoDAS GUI Overview
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

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
March 2005GeoDAS GUI Overview
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

New GeoDAS Features:Electronics Charts: DNC, S-57, BSB, ARCS
March 2005GeoDAS GUI Overview
New GeoDAS Features:Survey / way-point Layout (2-D)
March 2005GeoDAS GUI Overview
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 note 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

Mission Planning & Execution: Step 1: Select your region of interest
Point and Click on a location on one of several user selectable base maps
March 2005GeoDAS GUI Overview
Mission Planning & ExecutionStep 2: Zoom in
Zoom in to map limits to refine selection
March 2005GeoDAS GUI Overview
Mission Planning & ExecutionStep 3: Refine selection from chart
Charts, if available, are auto-loaded to help define area(DNC, S-57, BSB, etc.)
March 2005GeoDAS GUI Overview
Mission Planning & ExecutionStep 4: Name/Define Project
Supply a project name, description, sampling/logging requirements, and refine position/ROI
