A profile is a curved line which graphically portrays the intersection of a vertical plane with the surface of the earth. I depicts O a.stationings and the location of points backsighted as well as those foresighted b.ground elevation of selected critical points along a surveyed line and the horizontal distances between these points c. the correct position of the reference datum used d. all natural and man-made features along the surveyed route

Which of the following is false about the characteristics of contour lines? Select the correct response: Contours are perpendicular to the direction of maximum slope. The direction of rainfall run-off in a map area can be determined from this characteristic. Contour lines are irregularly spaced on uniformly sloping ground. Contour lines tend to parallel streams. Rivers usually have a flatter gradient than do intermittent streams. Each contour line must close upon itself either within or outside the borders of the map. A series of closed contour lines represents either a hill or depression. The elevations of the index contour lines will indicate which series represents a hill and which represents a depression.

13. A surveyor needs to determine the coordinate of an inaccessible location, point C. Setting up on point A, they sight point B (due east of point A) and set 0 on their total station. The measured distance between A and B is 400 m. The surveyor points the total station at point C (north of point B and east of point A) and reads an angle to the right of 340°20'15". Given that the UTM coordinate of point A is 680100.455 mE, 4912081.750 mN (UTM 17T, NAD83) what are the coordinates of points B and C?
