4. In figure 1, direct and reverse directions observed with a total station instrument from A to pints B, C, and D are listed below. Determine the value of the four angles, and the horizon misclosure (refer to sections 8.9 & 8.10). [note that the figure should include four angles instead of three, for example- x, y, w & z] Direct: 0°00'00" 98°22'58" 189°19'33" 267°42'44" 360°00'02" Reverse: 0°00'00" 98°23'00" 189°19'33" 267°42'40" 360°00'02" y Figure I Angles 4 Misclosure

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.
