Golfe du Lion · Pilot Zone

Coastal monitoring
without the
scientific toolkit.

Vaguel analyzes satellite imagery to track shoreline evolution, turbidity, and coastal risk — then generates a full report. Municipalities, engineers, and coastal managers: no Python required.

What you get, on every analysis

Five modules working together to give coastal professionals a complete picture — not a collection of disconnected data points.

Shoreline Evolution

Historical shoreline positions extracted from satellite imagery. View change over years, identify erosion and accretion hotspots, and see transect measurements with annual rates.

Sentinel-2 · Landsat · Mock

Turbidity Mapping

Surface turbidity patterns and sediment plume detection. Track water quality events, sediment transport corridors, and pollution signals across the coastal zone.

NTU index · Mock layer

Indicative Bathymetry

Estimated shallow-water depth from optical imagery. Disclaimer included — for environmental assessment, not navigation.

Non-navigational · Indicative only

Risk Score

Composite coastal risk score built from erosion rate, exposure, and water quality indicators. Confidence score tells you how much to trust the data.

Multi-factor · Confidence-weighted

Automated Report

Executive summary, maps, transect tables, turbidity analysis, and confidence caveats — ready to print or share. Every data point labeled with source and reliability.

Print-optimized · PDF-ready

Architecture for Growth

Modular design means each module — shoreline, turbidity, bathymetry — is independently swappable. Ready for Sentinel-2, Landsat, Copernicus Marine, and Google Earth Engine integration.

Sentinel-2 ready · GEE-ready

Five pilot sites. One coastline.

Analysis starts in the Golfe du Lion — a well-documented stretch of Mediterranean coast with active erosion, varying substrates, and strong institutional interest.

Port-la-Nouvelle
Urban harbor coast, engineered shoreline, mixed sediment. Baseline for urban coastal monitoring.
43.02°N · 3.04°E
Gruissan
Lagoon barrier beach system. Wetland interface, sediment transport dynamics, natural + managed coastline.
43.11°N · 3.09°E
Sète
Historic fishing port on a basaltic headland. Rocky coast + sandy pocket beaches. Mixed substrate complexity.
43.40°N · 3.80°E
Saintes-Maries-de-la-Mer
Camargue regional capital. Wide tidal flats, low sandy coast, salt marsh interface. High sensitivity to storm events.
43.45°N · 4.42°E
Leucate
Open sandy coast backed by limestone cliffs. Strong Mistral exposure. High-energy beach-dune system with documented erosion.
42.91°N · 3.03°E

How the analysis works

Vaguel combines satellite-derived shoreline (SDS) detection with confidence scoring to give you results you can actually trust.

  1. 01
    Select a zone

    Draw a polygon on the map or choose a pilot site. Set your analysis period — annual, seasonal, or event-based.

  2. 02
    Run the modules

    Choose which analyses to run: shoreline evolution, turbidity, bathymetry, risk scoring — all, or just the ones you need.

  3. 03
    Review results with confidence scores

    Every data point comes with a confidence indicator. Higher quality imagery and more images mean higher confidence.

  4. 04
    Export the report

    Full executive report with maps, transects, caveats, and confidence badges — formatted for print and PDF export.

Confidence scoring

Your results are only as good as the data quality. Every analysis score reflects:

  • Cloud coverage Lower = better
  • Image count More = better
  • Tide consistency Matched = better
  • Water clarity Clearer = better
  • Shoreline type Sandy = best
Port-la-Nouvelle: sandy coast, typically high confidence for SDS extraction.

Built on scientific honesty

Vaguel never hides the uncertainty. Every layer displays its confidence score. Every report includes methodological caveats. Bathymetry is labeled indicative, not navigational. Shoreline comparisons note sensitivity to tide, waves, and cloud cover.

We don't pretend mock data is real — labels are clear, methods are documented, and every number comes with its reliability context.

The Golfe du Lion won't wait.

Erosion rates of 1–2 m per year are documented at multiple sites. Mistral and Tramontane winds reshape beaches seasonally. Sea-level rise is accelerating Mediterranean storm impact. The data exists — in satellite archives, in institutional databases, in scientific literature. Vaguel makes it accessible, visual, and actionable.

The MVP is built on mock data. The architecture is built for the real thing.
