The Evolution of Map-Making

The practice of cartography, or map-making, dates back to ancient civilizations. The earliest known maps, such as the Babylonian Map of the World from the 6th century BCE, were inscribed on clay tablets. These early representations were not always geographically precise but served crucial functions, including defining property boundaries, planning military campaigns, and depicting mythological landscapes. Ancient Greek scholars like Anaximander and Ptolemy made significant contributions, introducing concepts of latitude and longitude and attempting to create more systematic, scaled representations of the known world.

The European Age of Exploration in the 15th and 16th centuries spurred a revolution in map-making. As sailors ventured into unknown waters, the demand for accurate navigational charts grew exponentially. This era saw the development of the Mercator projection in 1569, a cylindrical map projection that became the standard for nautical charts because it represents lines of constant course as straight segments. While integral for navigation, this projection significantly distorts the size of landmasses near the poles, making Greenland appear much larger than Africa.

In the modern era, cartography has been transformed by technology. The advent of aerial photography, satellite imagery, and Global Positioning Systems (GPS) has provided data of unprecedented accuracy. Geographic Information Systems (GIS) now allow cartographers to create dynamic, layered digital maps that can be updated in real-time. These tools have expanded the application of maps far beyond navigation, into fields such as urban planning, environmental science, and disaster management.
