Calculation preci 9. A survey was done on local coordinate systems. Coordinates are given as follow: Control Point Northing (FT) Easting (FT) A 1000.000 5000.000 B 1350.000 6250.000 C 1120.000 8300.000 D 770.000 5650.000 As advised by your project manager, you have to transform the surveyed coordinates to a project coordinate system to coincide with existing engineering and architectural plans, where point A is held for translation and line AB is held for rotation. Control Point У Northing A (FT) 20000.000 60000.000 Easting (FT) B 20000.000 61298.076 a. What is the rotation angle in DMS? b. What is the translation in N and E direction? c. What are the project coordinates of control points C and D? d. A survey technician rotated the traverse -40° by mistake instead of rotational angle in section a. If the translation is the same, what would be the project coordinate of CP B in this case?
