2.      Field Records.

a.      Forward and backward bearings: the summation should be 180^o.

b.      Distance measure and unit

c.       Date observed

d.      Observed by who?

e.      Recorded by who?

f.        Coordinates of control points

g.      Instrument tests

h.      Check on controls

3.      Computations

a.      Correction values and how they are distributed

b.      Coordinates computations

c.       Area computations

d.      Computed by who?

e.      Checked by who?

4.      Plan

a.      Title and location

b.      Scale

c.       Origin / Datum used

d.      North arrow

e.      Size (Area or Length)

f.        Contour interval

g.      Coordinates of control

h.      Coordinates system

i.        Beacons

j.        Boundary colour (Re)

k.       Bearing and distance colour and location on boundary line

l.        Units metre, degree, etc)

m.    Contour colour (in brown)

n.      Connection survey (key plan in blue)

o.      Features drawn

5.      Report

a.      Introduction

b.      Project size, owners and location

c.       Planning: government controls and instruments used
