The elevation of station Alpha is 680 m while that of Charlie is 620 m. In between stations Alpha and Charlie is station Bravo with elevation 645 m. The distance from Alpha to Bravo is 12 km and from Bravo to Charlie is 15 km. a.) Find the elevation of the line sight at station Bravo with the instrument placed at station Alpha such that station Charlie would be visible from station Alpha considering Earth’s curvature and refraction. b.) Assume that Sta. Bravo will obstruct the line of sight from Sta. Alpha while observing Sta. Charlie and a 4-m tower is constructed on top of station Bravo. Find the height of equal towers at stations Alpha and Charlie in order that the 3 stations as observed from station Alpha will still be intervisible. c.) Without constructing any tower at station Bravo, what height of tower must be constructed at station Charlie so that both stations Bravo and Charlie would be visible from station Alpha?

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.
