- Topographical maps, also known as general purpose maps, are drawn at relatively large scales.
- These maps show important natural and cultural features such as relief, vegetation, water bodies, cultivated land, settlements, and transportation networks, etc.
- These maps are prepared and published by the National Mapping Organisation of each country. For example, the Survey of India prepares the topographical maps in India for the entire country.
- The topographical maps are drawn in the form of series of maps at different scales. Hence, in the given series, all maps employ the same reference point, scale, projection, conventional signs, symbols and colours.
- The topographical maps in India are prepared in two series, i.e. India and Adjacent Countries Series and The International Map Series of the World.
