Breaking Tradition: How SSDM and ArcGIS are Modernizing Subsea Survey
Taylor Brown (GIS Analyst, AUV Group)Katherine Butcher (Survey Ops Manager, SSDM Taskforce Member)
Seabed Survey Data Model (SSDM)
Presentation Goals
• What is SSDM?
• How does it differ from historic data deliverables?
• Survey contractor benefits for SSDM & GIS implementation?
• Operator benefits from SSDM & GIS implementation?
• Room for improvement?
• Next steps?

What is SSDM?
Seabed Survey Data Model
• Subsea Survey Geophysical and Hydrographic Data Management & Deliverables Template
• 2011 Release by IOGP • Geomatics Group Geo-
Information Subcommittee
• SSDM Task Force
• IOGP & Operator “Flavors”
DOF Subsea – ESRI PUG – 10 April 2015 4
SSDM Purpose & Inception• Offshore Field Development & Data Management Tool
• Seabed & Shallow Sub-Surface Features (10’s of metres, i.e. not for Exploration)
• Standardize data for a full project life cycle
DOF Subsea – ESRI PUG – 10 April 2015 5
Data Model Structure
• File or Personal Geodatabase• 4 Feature Datasets
• 30 Feature Classes
• Hydrographic, Geophysical & Environmental Survey Templates
•Subsea Infrastructure Siting:• Feature Locations & Attributes
• Geohazards
• Environmental Conditions
