Explore the conditions. Choose the right coastal & shallow-water mapping window.

Assess your coastal AOI with Copernicus Marine water-clarity indicators and indicative optical mapping depth. Use satellite or your own aerial imagery for a professional SDB or seabed classification project.

Candidate mapping datesScreen up to 16 evenly spaced dates across your window, then rank the best available marine conditions. No imagery acquisition is required.

Secchi depth multiplier ⓘ

1.00×

Used only to calculate an indicative visibility-depth proxy. Actual SDB/classification depth requires image-specific assessment.

A short free contact form unlocks analysis immediately. No password or email confirmation.

Optional Sentinel-2 discovery

Look up acquisitions where available. This is separate from the water-quality suitability analysis and is not needed if you use imagery of other providers.

Sentinel-2 search has not been run.

Or check the water conditions on one date

Works independently of any satellite acquisition; displays available Copernicus Marine values for that day.

Draw an AOI to begin.

Data & limitations

Suitability dates are sampled evenly across your window, not every date. Copernicus Marine values are coarse and may not capture small-scale coastal conditions. Sentinel-2 scene cloud is optional metadata, not the AOI cloud fraction. The ESA true-colour basemap is a 2021 mosaic, not imagery from your requested dates. Screening is not a substitute for image-specific validation.

Best candidate dates

Evaluate sampled dates from your chosen time window using available water-quality indicators; Sentinel-2 discovery is optional.

How to interpret these results

Ranking uses available Copernicus Marine Secchi depth, Kd490 and chlorophyll-a values at a subset of dates within your time window. Sentinel-2 acquisitions are optional and are never required for the ranking. A high rank does not confirm that any optical image is cloud-free, free of sunglint, or suitable for SDB. The optical depth is Secchi × your selected multiplier, not a measured maximum mappable depth. The full BlueVision workflow includes pixel-level cloud/shadow/water screening, atmospheric and water-column assessment, reference-based validation and uncertainty analysis.

Request professional satellite-derived bathymetry, pixel-based seabed classification or both. Your project AOI and available screening results are attached automatically, so our team can prepare a tailored quotation.
