schema/objects/lineations-data-pointset/1.3.0/lineations-data-pointset.schema.json

See also: pointset (base schema), planar-data-pointset (planar orientation measurements).

Overview

The lineations-data-pointset schema is a variant of the generic pointset schema. See that schema for general information.

It enhances the base pointset by allowing lineation data to be associated with each point.

Lineation data

The lineation data is specified using two angles.

trend angle. The azimuth of the lineation direction.
plunge angle. The angle below the horizontal that the lineation plunges at.

The angles are similar to the first two used for specifying rotations. The dip_azimuth and dip pair correspond to the trend and plunge of the down-dip direction (itself a lineation) on the rotated xy plane.

Locations

To define a pointset, the object requires a locations property.

This property has three sub-properties, one with the lineation data and two from the generic pointset schema.

lineations - a two column float array with the trend and plunge angles.
coordinates - an array property with the coordinates (xyz) of each point. The x, y, z columns follow the axis order declared in the object's coordinate_reference_system — see Coordinate reference systems and axis order.
An optional attribute list.
