Lines AB and BC are on a straight line. The stadia intercept from A to B which are on the same level is 0.813 m. The stadia interval factor of the instrument used is 99.90. The same instrument was used to measure the distance BC where C lies + 18° 25’ above B with stadia intercept of 0.723 m. a) Draw a diagram b) Find the total length from A to C. c) What is the difference in elevation between A and C?

Q: Q₂-Calculate the vertical movement of points A, B and C

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.
