The surveyor established the stadia interval factor of a theodolite by setting up the instrument 50 m from the leveling rod and taking the upper and lower stadia hair reading as 2.166 and 1.665, respectively. Afterwards, the theodolite was used to determine the horizontal and vertical distance of a control point to the contstruction site. The theodolite was set-up in the control point, and the following data was gathered: STA OBS A m Elevation of control point: Height of instrument (fr ground): Determine the following: Upper Middle (m) (m) 2.446 Lower Vertical (m) Angle (°) 1.650 1.650 b) Elevation of construction site 8.500 m 1.100 m Remarks 10.256 construction site a) Horizontal distance of control point to construction site

State Plane Coordinate Systems

The state plane coordinate system (SPCS or SPS) is a collection of 124 coordinate systems or geographic zones prepared for particular regions of the U.S. Every state consists of one or more than one state plane zone, the boundaries of which generally follow the county lines. Inside the U.S., there are 110 zones in total, 10 more zones in Alaska, 5 in Hawaii, and 1 for Puerto Rico and US Virgin islands. The system is extensively used for geospatial and geographic data assembling by the state and local governments.
