Study Notes
Map Definition and Characteristics
- A map is a graphical representation of a part of the earth's surface in the correct positions relative to a coordinate reference system at an established scale.
- Maps are always smaller in size than the environment they represent.
- The reduction in size is expressed in terms of map scale, which represents the relationship between distance on the map and corresponding ground distance.
Map Scale
- Map scale can be expressed in statement scale or ratio form.
- It represents the relationship between distance on the map and corresponding ground distance.
Topographic Map
- A Topographic Map is a detailed and accurate illustration of natural and man-made features on the ground.
- Features represented on a topographic map include:
- Water bodies (rivers, lakes, etc.)
- Forest areas
- Urban and settlement areas
- Roads
- Railways
- Power transmission lines
- Contours
- Elevations
- Other human-made features
- A topographic map is a two-dimensional representation of the earth's three-dimensional landscapes.
Topographic Map Construction Elements
- Colors are used to represent different features on a topographic map.
- Classes of features, lines, symbols, letters, and numbers are used to represent different information on a topographic map.
- Map scale is a major element of topographic map construction.
