On Defect table:
- What are Fracture Set and Defect Number for?
Fracture Set and Defect Number were added for AGS format. This is an excerpt from AGS 4.1.1 AU 1.2:
• DISC_NUMB data variable is null (Rule 12) when logging discontinuity sets or zones.
• Each discontinuity set or zone must be given a unique set reference number in FRAC_SET. For example, joint sets may be numbered J1, J2, J3 etc, bedding discontinuities as B1, B2 etc. The use of FRAC_SET provides the link between the DISC and FRAC Groups.
