This geographic dataset contains the 400-metre isobath line, representing points of equal depth along Portugal's maritime area. Depth values are referenced to the Hydrographic Zero (ZH), using the EPSG:10349 vertical coordinate reference system (ZH Portugal Depth). The dataset is published via the Portuguese open data portal and is relevant for hydrographic, maritime, and coastal planning purposes, supporting navigation charts, bathymetric analysis, and marine spatial planning activities requiring standardized depth contour information for Portugal's national waters.Este Conjunto de Dados Geográficos (CDG) contém a linha isobatimétrica dos 400 m.
