In four centuries, seventeen voyages stretched Europe's charted world from one sea to the whole globe
Asked:“Create a chronological world map that shows how European geographic knowledge expanded during the Age of Exploration, from approximately 1400 to 1800… Animate major voyages in chronological order as colored routes moving across the map, gradually removing the fog and revealing newly charted coastlines and territories… Add a playable and draggable timeline… distinguish European cartographic ‘discovery’ from first human settlement by clearly acknowledging territories that were already inhabited.”
17 major expeditions, 127 dated generalized route waypoints, and an 18-step reveal timeline (a c. 1400 baseline plus 17 voyage-driven reveals) reconstruct how European-charted geography grew from the Mediterranean world of 1400 to a near-global coastline picture by 1795. Press play, or drag the year.
Read this first. The dark layer is a reconstruction of European cartographic knowledge, not of the world itself. Every coastline revealed here was already inhabited, named, mapped, traded across, and expertly navigated by Indigenous peoples. Route coordinates are generalized modern-coordinate waypoints assembled for visualization — not reconstructed daily ship positions — and uncertain landfalls are labeled. Fog holes are interpretive buffers, not claims that whole regions became instantly known.

Portugal opened the sequence: Dias rounded the Cape in 1487–88 and da Gama reached Calicut by 1498, joining Atlantic and Indian Ocean charting within a decade — along coasts long navigated by Khoikhoi and Indian Ocean societies. kids.britannica.com
The 1519–22 Magellan–Elcano voyage, 10 waypoints here, carried European charts across the Pacific for the first time and completed the first circumnavigation. manilatimes.net
Cook's second voyage (1772–75) expanded knowledge by subtraction: crossing the Antarctic Circle shrank the plausible extent of a temperate Terra Australis rather than adding a continent. clydebuilt.com
The series closes with Vancouver's 1791–95 survey from California to Alaska, which ruled out a continuous inland passage at those latitudes. catalogue.nla.gov.au

Interpretive synthesis for visualization: 17 expeditions, 127 dated generalized waypoints (108 + 19 for Cook's later voyages), and an 18-item reveal timeline compiled from the linked historical reference pages. “Known” means documented in European cartographic traditions only. Coordinates are modern and generalized, not reconstructed ship tracks; fog reveals are interpretive corridor buffers around traveled waters and named coasts; Ptolemaic and traveler-derived interior knowledge is treated as lower confidence. Base geometry: Natural Earth 110m via modern country outlines, shown only where revealed. Some intermediate ports were simplified for space.
