Principles of
Surveying:
The fundamental principles upon
which the various methods of surveying are based are:
1.
Location of a point by measurement from two points of
reference
After deciding the position ofpoint, its reference
must be kept at least from two permanent objects or stations whose position
have already been well defined.
2.
Working from whole to part
This is to localize minor errors
and to prevent accumulation of errors. First a control points are established
with higher precision for large area and minor control points are then
established within the main area with less precise methods.
If
reverse process is repeated, then errors will expand to greater magnitudes.
