Mapping of a ground in front of CSUF Engineering building was done with a four sided closed traverse. Assuming that the angle measurement is accurate, interior angles of only three traverse stations were measured. Northing, Fasting, and Elevation of stations C and D were measured with GPS device. Rest of the surveying was done with the total station. The results obtained with field surveying are shown in the following tables. With the provided information, please calculate the Northing, Easting, and Elevation of stations A and B.

Calculate the precision of distance measurement with the total station.

Table 1. Northing, Easting and Elevation obtained from GPS Survey

Instrument Station	Prism Station	Horizontal Angle	Horizontal Distance (ft)	Vertical Distance (ft)
B	A	0°0'
B	C	73°45'	740.930	+3.8

D	C	0°0'
D	A	140°18'	281.00	-5.885

A	D	0°0^'
A	B	100°22'	401.850	+5.845

Table 2. Data Recorded in the Field Book From the Survey with Total Station

Traverse Station	Northing (Ft)	Easting (ft)	Elevation (ft)
C	5500.00	8300.00	246.885
D	5932.00	8550.00	248.985
