18.13 If a map is to have a 10-ft contour interval, which contours are labeled between the elevations of 5089 and 5230 ft?

If the distance two places on the map is 12cm, with the map scale of 1:2,000,000,what is the ground area of the farm land?

Question No. 2:                                                      (b) Find the area of the closed traverse? (Values are in feet

If a map is indicated to be on "National Map Accuracy Standards" at a scale of 1" 500, 90% of the well- defined horizontal positions must be in their correct position within approximately: 08 feet O 1.4 feet 10 feet O 17 feet O 167 feet

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.

Determine the equivalent length of 15000m on a graphic scale of a map whose representative fraction is 1:25000.

With an aid of diagrams describe azimuthal and conical map projections, giving advantages and disadvantages of using them
