A slope distance of 204.834 m was determined by EDM, the instrument and prism having been set up 1.645 m and 1.873 m respectively above their stations. The altitude angle between the stations was later measured as 2°17'40", the instrument station being the higher on the two. Calculate the horizontal length of the line.

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.
