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.

what is the answer to b. i & ii? The slope distance between twostations A and B measured with EDM when corrected for meteorological conditions and instrument constants,is 113.893 m. Theheights of the instrument and reflector are 1.739 m and 1.839 m, respectively, above the ground. To measure the vertical angle a theodolite was set up at A, 1.665 m above the ground and a target at B having height above the ground as 1.632 m. The measured angle above the horizontal was + 4°22′18″. Determine a. The horizontal length ofthe line AB. b. To what precision the slope angle be measured: if the relative precision of the reduced horizontal distance is to be 1/100000. if the reduced horizontal distance is to have a standard error of ± 1.8 mm.
The two—peg test is used to determine if the line of sight of the telescope is parallel to the axis of the bubble tube. A tilting level is set up halfway between points A and B and rod readings on both points are 1.969 m and 2.161 m, respectively. The level is then set up 3.50 m away from A along the extension of line AB and 53.50 from B. Then rod readings on A and B were recorded as 1.554 m and 1.728 m, respectively. Determine if the line of sight is inclined downward or upward and the amount by which the horizontal cross hair should be moved to adjust the line of sight.
The following tacheometric observations were made from station A to stations 1 and 2. The height of the instrument above the ground was 1.52 m. Take stadia interval factor and constant as 100 and 0, respectively. If the staff was inclined by 1° to the vertical, solve for the following:a. Error in horizontal distance if the staff is inclined towards theinstrument for the line A-1. b. Error in the vertical distance if the staff is inclined away from theinstrument for the line A-2. c. If the elevation of point 1 is 115.673 m, determine the correctelevation of point 2.
In determining the elevation of point A and the distance between two points, A and B, a theodolite is set up at A and the following data are obtained: z= 92°45', stadia interval = 1.311m, hi = 1.28m, and the line of sight at 2.62m on rod. The instruments constants are K=100.5 ad C = 0.305m. The elevation of B is 38.25m. Compute the distance AB and the elevation of point A. *Note: Zenith Angle is the angle from the vertical line (from the point above the observer). Distance AB: in meters Elevation of point A: in meters
