1. Contour lines: Contour lines are lines that connect points of equal elevation on a map. These lines show the shape of the land and the steepness of the terrain. The closer together the contour lines are, the steeper the terrain. The farther apart they are, the flatter the terrain.
2. Shading: Shading is a method of representing relief on a map by using different shades of color to show the elevation of the land. Darker shades are used to represent higher elevations, while lighter shades are used to represent lower elevations.
3. Hachures: Hachures are short, parallel lines that are drawn on a map to show the direction and steepness of slopes. The lines are drawn perpendicular to the contour lines, with the lines pointing uphill. The closer together the hachures are, the steeper the slope.
4. Spot heights: Spot heights are points on a map that are marked with the elevation of that point. These points are usually marked with a dot and a number indicating the elevation in meters or feet.
5. Hill shading: Hill shading is a method of representing relief on a map by using shading to show the direction of the slope. Lighter shades are used to represent slopes that face the light source, while darker shades are used to represent slopes that face away from the light source. This method helps to give a three-dimensional representation of the terrain.

1. Contour Lines
- Smoothly curved lines connecting points of equal elevation.
- Each contour line represents a specific height interval (e.g., 10 meters).
- Spacing between contours indicates slope gradient: closer contours indicate steeper slopes.

2. Hachures
- Short, parallel lines perpendicular to the slope.
- Length and thickness of hachures indicate steepness and height.
- Hatchures point downhill.

3. Hill Shading
- Shading that simulates the effects of light on the terrain.
- Darker areas represent steeper slopes facing away from the light source.
- Lighter areas represent gentler slopes or areas facing towards the light source.

4. Spot Heights
- Small numbers indicating the elevation at specific points.
- Usually placed on important features like hilltops or valleys.
- Provide additional detail to contour lines.

5. Triangulation
- A series of connected triangles that have a common vertex at the highest point.
- Each triangle is a small portion of the terrain.
- The height of the vertex is usually indicated by a spot height.
