In stadia leveling, the difference in elevation V is computed from the stadia intercept and vertical angle. If the value of stadia constant is 100(assumed errorless) and the errors in the stadia intercept and vertical angle are 0.003 and 45 seconds of arc respectively, evaluate the error in V for stadia intercept=1.200 and vertical angle=15 degrees. 1 V =, kssin20 + csino 2

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.
