Rapid, wide-area depth screening for early planning and reconnaissance
Currents, waves, water levels, and marine conditions to support design, construction planning, and safety.
We supports Satellite-Derived Bathymetry (SDB) as an early-stage planning tool to estimate shallow-water depths over broad coastal areas—useful when you need quick insight before field mobilization.
SDB is best for screening and concept development, and it is typically validated or supplemented with in-water surveys for engineering-grade requirements.
What SDB is best used for
- Early feasibility and concept planning
- Reconnaissance mapping of shallow coastal zones
- Identifying broad depth trends and potential constraints
- Planning field survey extents and priorities
- Large-area overview when time or access is limited
Important limitations
SDB accuracy depends heavily on:
- Water clarity / turbidity and bottom reflectance
- Wave conditions, sun glint, and seabed type
- Depth range (typically shallow waters; performance reduces with depth and poor clarity)
For construction, dredging, and contractual depth requirements, SDB should be treated as non-replacement for SBES/MBES bathymetry unless project specifications explicitly allow it.
Deliverables
- SDB depth rasters/grids (where feasible) and interpreted depth maps
- Contours and screening-level outputs for planning
- Comparison against any available control data (if provided)
- Summary report covering method, assumptions, confidence level, and limitations
- Optional field verification plan and survey prioritization (recommended for critical projects)
- Â
Quality and control
- Proper mounting/anchoring method based on site conditions
- Configuration aligned to monitoring objectives (bin size, sampling, interval)
- Data screening and validation, including spike removal and gaps reporting
- Clear reporting of limitations (biofouling, vessel interference, etc.
Recommended workflow
- Use SDB to screen and map broad depth patterns
- Confirm critical areas via SBES/MBES field survey
- Deliver an integrated dataset suitable for design and execution
Frequently asked questions
Can SDB replace a multibeam survey?
No for engineering-grade works in most cases. It’s a fast planning tool and needs validation for critical decisions.
Is SDB useful in the Gulf Region?
Yes in suitable conditions—especially for early planning, but performance varies by location and water clarity.
