Father of Dutch cartography, a major figure in modern cartography?

• A. Ptolemy
• B. Sebastian Münster
• C. Hipparchus
• D. Gerardus Mercator

Answer: (D)

Focus on a breakthrough in map projection and practical navigation that transformed how maps were used at sea. Gerardus Mercator, a 16th‑century Dutch cartographer, developed the Mercator projection, which preserves angles and makes compass bearings correspond to straight lines on the map. This conformal property lets sailors plot constant courses with accurate direction, a huge leap for navigation. He also advanced map production techniques and published influential atlases, helping to standardize modern cartography in Europe. While Ptolemy, Sebastian Münster, and Hipparchus all made important contributions to geography and mapmaking in earlier eras, none established the contemporary projection-focused approach and navigational utility that Mercator introduced, which is why he’s regarded as the father of Dutch cartography and a major figure in modern cartography.
