Agnostic visualization

Weakness zones can be either line geometries or polygon geometries. Line geometries are usually used for small weakness zones, polygon geometries for larger weakness zones.

Line Geometry

Labeling:

Dip value is show as number at the center of the line if dip between 15° - 80°, the unit is not shown. e.g. 35

Center Symbol Rule:

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

Color

•Color: fixed (red)

•Linestyle fixed (solid with crosses every 1.5m)

•Linewidth (fixed)

Polygon Geometry

•Labeling: At first point of polygon

•Tick symbol: At first point of polygon

•Linestyle of outline: solid

•Filling: # pattern (fixed texture) or hatch patten.

Color: fixed (red)

Linestyle: fixed (solid)

Filling: Cross hatch

Linewidth: (fixed)
