The upper and lower stadia hair readings on a stadia rod held at station B were observed as 3.50 and 1.00 m, respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 99.5. The height of the instrument above station A is 1.45 m and the rod reading is taken at 2.25 m. If the vertical angle observed is − 23 ∘ 34 ′ , what is the elevation of station B if the elevation of station A is 155.54 m above mean sea level?

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.
