Linear spatial object composed of a set of adjoining locations characterized by having the same elevation property value. It describes, together with other contour lines present in the area, the local morphology of the Earth's surface.
-- Description --
NOTE 1 The attribute propertyType is equal to 'height' in the case of contour lines and it is equal to 'depth' in the case of depth contours.

Description |
| contourLineType |
ContourLineTypeValue |
|
The type of contour line with regard to the normal contour vertical interval (if any).
-- Description --
NOTE This attribute is often applicable to contour lines describing the relief of a land-based area. For depth contours describing the floor of a water body is not always applicable.
|
| downRight |
Boolean |
|
Property indicating that the contour line spatial object is digitized in a way that the height of the elevation surface is lower at the right side of the line.
-- Description --
NOTE 1 In the case of contour lines, when the downRight attribute is 'true' this indicates that the height of the surface is lower at the right side of the line.
NOTE 2 In the case of depth contours, when the downRight attribute is 'true' this indicates that the depth of the surface is higher at the right side of the line.
