where [[sigma].sub.p] is the far-field stress tensor under the principal stress coordinate system, [[sigma].sub.g] is the far-field stress distribution tensor under the geographic coordinate system, [[alpha].sub.pg] is the azimuth of the maximum horizontal principal stress, and [[beta].sub.pg] is the angle between the direction of [[sigma].sub.v] and [Z.sub.g]-axis.

Database was linked to the layer Supply Sectors which was already georeferenced in SIRGAS 2000 reference Datum and in the geographic coordinate system.

Geomatics survey was essential before transmission pipeline construction work, done twice by private consultant in Pakistan's local geographic coordinate system. SSGC took decision in 2006 for the construction of pipeline but unfortunately it could not be executed due to law and order situation in Pakistan especially in Balochistan province and later all bench marks of pipeline alignment route were vanished by the locals.
