TRIGONOMETRIC LEVELING. A vertical angle of -12°25’ is measured to the top of a water tank from an instrument set up on a hill 585.00 meters away from it. The telescope of the instrument is 1.45 m above the ground whose elevation is 462.73 m. Making due allowance for the earth’s curvature and atmospheric refraction, determine the elevation of the base of the water tank is the tank is 32.0 m high. with complete solution adn figure of

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.
