The Evolution of Cartography

Early cartography served both practical and symbolic purposes, with some of the oldest known maps originating from Babylon. Ancient Greek scholars, such as Ptolemy, made significant contributions by introducing concepts like latitude and longitude in his work "Geographia," attempting to create a more scientific and accurate representation of the known world. These early maps, however, were often based on incomplete information and exploration, blending fact with mythology.

During the European Middle Ages, mapmaking often took a step back from scientific accuracy, with maps like the "T-O" map reflecting a more theological worldview centered on Jerusalem. The Renaissance revitalized a scientific approach to cartography, driven by an age of exploration. A pivotal innovation was the Mercator projection, developed by Gerardus Mercator in 1569. This map was invaluable for navigation because it represented lines of constant course as straight segments, but it came at the cost of significant size distortions, especially near the poles.

Modern cartography has been transformed by technology. The advent of aerial photography in the early 20th century, followed by satellite imagery and the Global Positioning System (GPS), has allowed for unprecedented accuracy. Today, Geographic Information Systems (GIS) integrate various layers of data onto digital maps, making them powerful tools for analysis in fields ranging from urban planning to environmental science. The focus has shifted from simple geographic representation to complex data visualization.
