Description

FRACTUREGeometry

Geometry

Geometri

Defines location and shape of the fracture

Property type: Geometry

FRACTUREPROGNOSIS

Prognosis

If true defines that this collection element is a prognosis and not an actually observed characteristic.

FRACTUREDIPDIRECTION

Dip direction

Stupningsriktning

The dip direction is the azimuth of the direction the dip as projected to the horizontal, which is 90° off the strike angle.

Property type: Numeric

Default Value: null

Validation rule: >= 0 and <=359

FRACTUREDIP

Dip

Stupning

Agnostic styling

Fracture with given Dip

•Dip is show as number at the center of the line if dip between 15 - 80 and with a line

•Dip is show as double-point symbol if dip is between 80 and 90

•Dip is shown as crossing-line symbol if dip between 0 and 15

•Dip direction is encoded by placing the symbol and text at one specific side of the line

Label rule: Dip

If persisting fracture then use slash character (every 3rd meter)
