Specification of ground level along pipeline axis (Input Table)

Data description/conditions:

Identifier: (toggleable)

Identification name of data reference point

Required

GROUND1:

Z-coordinate of ground level just before and at x-p ref. point

None / Required

(The value given for GROUND1 on the first data table line is valid for every value of X less than X-P(1))

UNCV1:

Uncertainty value for depth of pipeline axis below ground level

≥ 0.

[Default: 0.]

GROUND2:

Z-coordinate of ground level just after x-p reference point

None / Undefined

(The value given for GROUND2 on the last data table line (n) is valid for every value of X greater than X-P(n). If GROUND2 = Undefined it is assumed GROUND2 = GROUND1)

UNCV2:

Uncertainty value for depth of pipeline axis below ground level

≥ 0. / Undefined

[Default: 0.]

(The value given for UNCV2 on the last data table line(n) is valid for every value of X greater than X-P(n). If UNCV2 = Undefined it is assumed that UNCV2=UNCV1)
