on a map scale 1:25000, the map distance measured between two points X and Y is 32:75 cm. Determine the scale of a sketch of the same area in which the drawn distance between the same two points measures 10.916 cm.

What different methods can be used to show a map's scale? Select all that apply. bar scale contour lines representative fraction grid lines an equivalence relation giving the length of a fixed landmark such as a bridge or section of road

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.

a. what kind of topographic landform is represented in the illustration? b. What are the Bold contours called? c. what is the contour interval?
