3D Degrees from north Depth Distance along ray Radial horizontal offset with depth Offset expressed as a distance along a ray that originates from a central point with a third coordinate that indicates the depth below the earth or water surface. The angle of the ray is expressed as the first offset coordinate in degrees. The distance along the ray is expressed as the second offset coordinate. The depth below the earth or water surface is expressed as the third coordinate. Minimum depth (top) Depth interval below the earth or water surface. The mininum depth value is expressed first and then maximum depth value. Values are expresssed as negative numbers and become more negative in the downward direction. Depth interval 2D Maximum depth (bottom) 3D Degrees from horizontal Height, directional Degrees from north Distance along ray Height above the earth or water surface along a non-vertical line. The first coordinate is the angle of the ray from north expressed in degrees. The second coordinate is the angle of the ray from horizontal expressed in positive degrees. The distance along the ray is expressed as a positive number that increases with distance along the ray. ODM2 Spatial Offset Type Controlled Vocabulary A vocabulary for describing the type of SpatialOffset that exists between two SamplingFeatures. ODM2 Working Group Degrees from north Interval along a horizontal or longitudinal ray. The first coordinate is the angle from north expressed in degrees of the longitudinal array. The second coordinate is the minimum distance along the ray at which the longitudinal interval begins. The third coordinate is the maximium distance along the ray at which the longitudinal interval ends. Maximum distance along ray (end) Longitudinal interval Minimum distance along ray (begin) 3D Depth, directional Degrees from horizontal 3D Degrees from north Distance along ray Depth below the earth or water surface along a non-vertical line. The first coordinate is the angle of the ray from north expressed in degrees. The second coordinate is the angle of the ray from horizontal expressed in negative degrees. The distance along the ray is expressed as a positive number that increases with distance along the ray. Height interval above the earth or water surface. The minimum height value is expressed first and then the maximum height value. Values increase in the upward direction. Height interval Minimum height (bottom) Maximum height (top) 2D Depth Depth 1D Depth below the earth or water surface. Values are expressed as negative numbers and become more negative in the downward direction. Radial horizontal offset Offset expressed as a distance along a ray that originates from a central point. The angle of the ray is expressed as the first offset coordinate in degrees. The distance along the ray is expressed as the second offset coordinate. Degrees from north 2D Distance along ray 3D Offset expressed as a distance along a ray that originates from a central point with a third coordinate that indicates the height above the earth or water surface. The angle of the ray is expressed as the first offset coordinate in degrees. The distance along the ray is expressed as the second offset coordinate. The height above the earth or water surface is expressed as the third coordinate. Distance along ray Height Radial horizontal offset with height Degrees from north Height Height Height above the earth or water surface. Values are positive and increase in the upward direction. 1D 3D Distance in X direction Cartesian offset Offset expressed using cartesian coordinates where X is distance along axis aligned with true north, Y is distace aligned with true east, and Z is distance aligned straight up. Depths are expressed a negative numbers. The origin of the coordinate system is typically defined in the site description. Distance in Z direction Distance in Y direction
