A Civil Engineer proceeded to do the stadia survey work to determine the topography of a certain area. The transit was set up at a point A, with the line of sight horizontal, took rod readings from the rods placed at B and C which is 200 m and 60 m from A respectively. Stadia constant is 0.30 m. Rod B Rod C Stadia Interval 2.001 m 0.600 m Draw a diagram of the entire problem. Compute the stadia interval factor (clue: if there are more that 1 value, get the average) The same instrument was used for determining the elevation of point D with a stadia intercept of 2.12 m and a vertical angle of +4°22’. If the elevation of the point where the instrument was set up is 100 m, compute the elevation of point D given the middle reading of the stadia is 1.892. Compute the horizontal distance from the point where the instrument was set up to point D.

A: To Calculate :- The angle measured at point C (BCD)

Q: Answer fast

A: Step 3:Since, 3600" = 1° .So, 1" = (1/3600)° .That means, 40" = (40/3600)° . Hence,-40" = -0.0111…

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.
