Two index contours appearing on a contour map have elevations of 100m and 200m, if there are five intermediate contours between these index contours determine the contour interval. Select the correct response: 10m 25m None of these

Explain how agency benefits of a transportation project is estimated? Use a toll highway project to outline your proposed method.

The following perpendicular offsets were taken at 10 m intervals from a survey line to an irregular boundary line. The area in square metre enclosed between the survey line, irregular line, first and last offsets by Simpson's rule is : Perpendicular offsets, 5 m, 2 m, 4.5 m, 6 m, 1 m, 2 m, 4 m, 2.5 m, 4 m

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.
