During the 18th century, mapmaking became more scientific and precise. Improved instruments like the telescope and chronometer helped cartographers increase accuracy, shifting maps from decorative art to factual documents. Copperplate engraving stayed as the main printing method, producing fine lines, while hand-coloring added visual impact. French cartographers, such as the Cassini family, led national surveys with geodetic measurements and triangulation, while Dutch mapmakers like Joan Blaeu enhanced printing and atlas quality, ushering in a golden age of atlases.
Maps began including more information and notes to help users, and ornate decorations mostly gave way to scientific clarity, except for cartouches and borders. National and colonial ambitions guided map production to aid navigation and territorial claims. By the late 18th century, large-scale surveys set modern cartography standards. Today, 18th-century maps mix scientific knowledge with artistry, are prized by collectors, and have influenced later cartographic methods. They offer insights into Enlightenment exploration and geography.
