Q12: A detailed survey was carried out using a number of radiations from a total station set up on Station A to a target placed on an area on interest. Station A has the following coordinates as shown in the Table 8 on a local plane datum. Table 8: Point Easting (m) Northing (m) Height (m) A 255.751 176.286 42.623 The instrument is set up at a height of 1.565 m (h) and the target pole is set at a height (h.) of 1.690 m. A radiation was made to a feature labelled B: Bearing (B) = 240°25'20" Slope Distance (SD) = 11.682 m Zenith Angle (ZA) = 93°22'30" Calculate the coordinates of B including its height.

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.
