- Name
DepthCurve- Kind
- FeatureType
- Definition
- A navigational safety line indicating that no sounding of a lesser depth exists seaward of the line, but greater depths may occur on the shallow side of the line.
- Description
- Depth curves should not be confused with Feature: 'Depth Contour'. Depth curves are generalised, are biased towards safety of navigation, and do not fully follow the rules for contour formation, that is, contours must close on themselves, must be continuous, and must precisely represent the shape of the bottom.
