Maps:
- In general, maps are used to descale and represent the real world on a much smaller scale.
- Maps help analyze, record and creating scalable paths (or) graphical waypoints for existing geographical locations.
- Maps are useful in presenting key facts within a geographical context and thus enabling easier and quicker access to a complex concept descriptively.
- A map is a diagrammatic representation of an area of land or sea showing physical features, cities, roads, etc.
- Cartography is a science or art of making maps. The people who study (or) make maps are called cartographers.
Scaling:
Scaling refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a \(1\):\(100000\) scale map, \(1\) \(cm\) on the map equals \(1\)\(km\) on the ground.
- A neighborhood building: \(1 cm = 20\) \(cm\)
- A city map on a full page: \(1 cm = 2\) \(km\)
- India’s map on a full page: \(1 cm = 200\) \(km\)
- The world Map: \(1 cm = 3000\) \(km\)
