The main methods of relief display are as follows :
- Hachure Method : For relief representation it is a method of displaying topography by which small, large, thick, thin and segmented lines. The actual height of a place cannot be shown by this method. In this only the can shown the part 15 represented by dense lines and the law slope by distant lines.
- Hill Shading Method : This method is the method of slope display. Through this is intensity and retardation of the slope is displayed with the help of rays of vertical and oblique light. The standing gradient is demonstrated by light shadows. In this method there is no knowledge of the slope and height of the slope.
- Flood Mark Method: The mark showing the height measured above sea level on permanent objects like buildings, bridges, all stones by actual surveys is called Bench mark and the height is expressed by writing the letter BM on the Map.
- Spatial Height Method: The height measured at a particular place with the help of plane Symbol is called the Spatial height. In this method, the height of different place in the map is written by points.
- Trigonometric Station Method: This method is related to the points which were used as stations while doing the survey. In this, the height above sea level is written by making a triangle on the map.
- Strat Ranjan Method : It is a method of displaying topography in which surface elevation and depth are displayed by different students. In these, the sea of water body is shown in blue. The plains are shown in green and the mountains in light brown color, while the snowy region is shown in white color.
- Contour Line Method: The method of embossing with the help of contour lines considered to be the best. This is a standard method. In fact, contour lines are imaginary lines drawn on a map by joining points or places of equal elevation in sea level on the surface.
