Question
1) (a)Draw a sketch of the following figure and determine, by the cross-coordinate method, the area of the figure which is defined by the following coordinates: Station Eastings Northings A 613.26 418.11 В 806.71 523.16 C 942.17 366.84 901.89 203.18 E 652.08 259.26 (b) You are asked to produce contours for a topographic map of an area where you wish to design and build an offi building. Describe two methods and the process you can use to obtain the spot heights to produce the contours using field survey methods. Indicate what factors would determine which of the methods is chosen for a given situation. Also indicate how you would improve the accuracy of the contour lines by adjusting the specifications for your observations.
