Location Measurement In US&R

CP (x,y,z)

MP = Monitoring Point

Current thinking for US&R is to set the X axis parallel to the side of the building

facing the instrument and the Y axis perpendicular to the building. To do this, a

location on the structure is used to set the azimuth angle to 0

refers to the point used to set the azimuth as the back sight, BS). The location

must be chosen such that the 0

building facing the instrument.

If creating a new coordinate grid, give the new station widely different

coordinates such as:

different coordinates are beneficial in the event that E, N, Z is mixed up with N,

E, Z. This difference helps the StS quickly translate a change in coordinates to

a magnitude and direction of movement.

Once established on a station, set several Control Points (CP):

1. They can be used as alternate instrument stations.

2. This allows options if some sites are blocked by equipment or if you need

to set up the instrument at a new remote location.

3. This allows choices if reestablishing the grid from a new location not

previously located by survey.
