Who we help
Government

Sea-level rise, storm surge, and erosion cost local governments hundreds of millions annually, forcing reliance on public funding to repair and protect property, ports, and critical infrastructure. In rapidly urbanising, high-risk coastal regions, Ocean Ledger equips authorities with accurate, transparent shoreline data and forecasts, delivering far greater reliability and flexibility than national datasets.

898M

Is the number of people living in low-lying coastal areas globally, and it's likely to increase.

5M

Is the number of Europeans under annual threat of a 100-year extreme sea level at risk from coastal flooding under high-end warming.

$10T

Is the amount of goods and services that US coastal counties produce. They also employ 54.6 million people.
What we do to help

We leverage a suite of medium and high-resolution satellite-derived data products that capture seabed depth, shoreline movement, and coastal defences.

By analysing past and future coastal trends, we equip local authorities with the knowledge to safeguard communities and infrastructure to strengthen long-term resilience.

Nuanced view of coastal physical risk
We help carriers navigate highly exposed coastal zones, clarify outdated or incomplete data, and reduce uncertainty in managing risk. By combining different loss perspectives and detailed shoreline data, we create a clearer, more accurate view of risk.
Targeted assessment efforts
By leveraging satellite imagery to monitor large areas, we can significantly reduce the workload for ground teams, allowing them to focus their efforts. This approach enhances efficiency, accelerates operations, and provides valuable indicators or benchmarks for decision-making.

Frequently Asked Questions

Accuracy

  • Open-source tools and datasets are incredibly valuable resources and can be a good starting point, depending on budget and project scale. However, they often contain data and time gaps, and their accuracy breaks down when applied at local scales.
  • Ocean Ledger fills these gaps with spatially accurate, frequently updated data — particularly useful for projects tied to financial instruments (e.g. biodiversity credits), which demand up-to-date and verifiable baselines.

Usability

  • Open-source data can typically be downloaded, but it often lacks flexibility for deeper manipulation.
  • Ocean Ledger delivers precise, forecastable data tailored to user needs — and enables integration of field data for comprehensive, context-specific analysis.

Monitoring

  • National open datasets are usually updated every 5–10 years, with limited projections and low transparency.
  • Ocean Ledger updates every 6 days, provides high-resolution forecasts (every 50–100m), and includes uncertainty maps to support rapid decision-making for changing coastal conditions.

Transparency

  • Open data may reference accuracy metrics but rarely discloses full model uncertainties.
  • Ocean Ledger provides spatial and temporal uncertainty metrics, F1 scores, and performance data for every model and output.

We distinguish between Primary Satellite-Derived Data Products and Advanced Insights. The latter are enhanced outputs that build upon or integrate the core insights from the Primary Products to deliver deeper, more actionable insights.

Currently, our available data products include:

  • Primary Satellite-Derived Data Products
  • Advanced Insights (enhanced outputs that build on core products for deeper analysis)

This is the main interface between Ocean Ledger and its clients. Built in-house, the dashboard offers:

  • Seamless access (API, raw data downloads) to spatial data products for erosion, bathymetry, natural capital
  • Heatmap analysis (with customisable thresholds) to identify erosion, storm surge and ecosystem degradation
  • Standardised & Custom Solutions for Scenario Analysis, Climate Modelling & Restoration Uplift
  • Trigger thresholds for early warning and risk mitigation
  • Accurate baselines and continuous monitoring
  • Transparency on data sources, accuracy, and uncertainty metrics

Yes! Please fill out our online form, and we’ll get back to you with options to demonstrate our solution for your project.

Most flood-risk and cat risk providers leverage the same digital elevation models (DEM’s). Ocean Ledger provides a next-generation DEM that fuses bathymetry, shoreline and natural defenses, which are key variables in identifying where there is more or less storm surge risk along a coastline.
