For depth up to 50m, the vertical precision of soundings varies from 30cm to 1m and the horizontal precision varies from 1 to 20m. In deep ocean, the vertical precision is mainly around 1 or 2% of the bottom depth. It is sometimes more, it depends on the technology used. The data are referenced to ZH which is assimilated to LAT. Data are corrected for sound velocity variations. Data are acquired during the campaign S196301600 (http://dx.doi.org/10.17183/S196301600). // Instruments: Sondeur monofaisceau (pas d'élément sur ce sondeur) // Number of soundings: 4385 Les levés bathymétriques sont des semis de sondes issus de levés provenant de la base des données diffusables par le Shom. Pour les fonds jusqu à 50m, la précision verticale des sondes varie de 30cm à 1m et la précision planimétrique de 1 à 20m. Au-delà, dans les grands fonds, la précision verticale est majoritairement de l ordre de 1 à 2% de la profondeur du fond. Parfois, elle est plus élevée selon la technologie utilisée. Les données sont référencées au ZH qui est assimilé à la Plus Basse Mer Astronomique (PBMA). Les données sont corrigées des variations de la célérité du son dans l eau.

Uncertainty_Vertical 2019-12-05 publication 0.02z+1 true Bathymetric datasets, collected before 1970, are historical surveys acquired with leadlines (and single-beam echosounders after 1930-1940). Quality controls and qualification, conducted by the Shom, on these datasets are not exhaustive. Datasets may present significant uncertainties and errors may remain. Ask the data centre for details. Levés bathymétriques collectés avant 1970, données historiques principalement acquises au plomb de sondes (et au sondeur monofaisceau après 1930-1940). Le contrôle et la qualification conduits par le Shom sur ces données ne sont pas exhaustifs. Les données peuvent présenter des incertitudes importantes et des erreurs peuvent subsister.
