1. Contour lines: Topographical maps use contour lines to represent the elevation of the land. These lines connect points of equal elevation, allowing users to visualize the shape and steepness of the terrain.
2. Scale: Topographical maps include a scale that indicates the ratio of distance on the map to actual distance on the ground. This helps users accurately measure distances and plan routes.
3. Legend: A legend on a topographical map explains the symbols and colors used to represent different features such as roads, rivers, forests, and buildings.
4. Grid lines: Topographical maps often include grid lines that help users locate specific points on the map and navigate more easily.
5. Geographic coordinates: Topographical maps typically include latitude and longitude coordinates to help users pinpoint their location on the map.
6. Relief shading: Some topographical maps use relief shading to add a three-dimensional effect to the map, making it easier to visualize the terrain.
7. Contour interval: The contour interval on a topographical map indicates the vertical distance between contour lines. A smaller contour interval means a steeper terrain, while a larger interval indicates a more gradual slope.
8. Benchmark locations: Topographical maps may include benchmark locations, which are known elevation points that can be used as reference points for navigation and measurement.
9. Landmarks and features: Topographical maps often include important landmarks and features such as mountains, lakes, and trails to help users orient themselves and plan their route.
10. Topographic symbols: Topographical maps use specific symbols to represent different features such as roads, buildings, vegetation, and water bodies. These symbols help users interpret the map more easily.

Key Features of Topographical Maps:
1. Contour Lines:
- Represent lines of equal elevation above a reference datum (usually sea level).
- Indicate the shape and slope of the landform.
- Closely spaced contour lines represent steep slopes, while widely spaced lines indicate gentle slopes.
2. Hachures:
- Shaded lines or dashes used to represent cliffs, steep slopes, and other abrupt changes in elevation.
- Indicate the direction of slope and the angle at which it descends.
3. Spot Heights:
- Small, precise points marked with their elevation above sea level.
- Often used to supplement contour lines in areas with complex terrain.
4. Benchmarks:
- Fixed, permanent reference points with known elevations.
- Used as a basis for leveling and height determinations.
5. Trig Points:
- Surveyed reference points with precisely determined positions and elevations.
- Used for navigation, surveying, and mapping.
6. Grid Lines:
- A network of horizontal and vertical lines used to locate points on the map.
- Allow for precise measurements of distances and directions.
7. Legend:
- Explains the symbols, colors, and abbreviations used on the map.
- Guides the user in interpreting the features and information represented.
8. Scale:
- Indicates the relationship between the map distance and the real-world distance.
- Allows for accurate measurements and calculations.
9. North Arrow:
- Shows the direction of true north.
- Essential for accurate navigation and determining the orientation of the map.
10. Relief Shading:
- A technique that uses shading to simulate the natural appearance of landforms.
- Helps in visualizing the topographic features and the interplay of slope and aspect.
