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.

A theodolite is set up at one end of a level line 150.0 m long. The line is marked by stakes at every 30.0 m and a stadia rod is held at each stake. The stadia intercept at each station of the rod is observed as follows: 0.302, 0.600, 0.899, 1.207, and 1.506 meters, respectively. Compute the stadia interval factor (K) for each distance and also determine the average value of K.Take C = 0.300
The theodolite is placed in the middle of points A and B, where the subtense bar is positioned. The instrument reads 0°24’56.2” and 0°44’36.8” for A and B. Compute the distance between A and B.
