Maps and Cartography

Maps and cartography are essential tools in geography that enable us to visualize and understand the Earth’s surface and its features.

Cartography is the art and science of creating maps, which involves the use of sophisticated technology and techniques to accurately represent the Earth’s physical and cultural features.

Maps provide a visual representation of the world, allowing us to identify patterns, explore spatial relationships, and navigate through unfamiliar terrain.
