This map, along with Gastaldi's Tierra Nueva, was the first copperplate map devoted to North America. The transition from wood block to copper plate allowed for finer detail, which was important for Ptolemy's Geografia as it contained the first regional maps of the American continent and was the most comprehensive atlas published between Waldeemuller's Geographiae of 1513 and Abraham Ortelius' Theatrum of 1570. Cartographically, the map covers the region from Florida to Baja California and south to the Yucatan. Inland detail is confined to basic topography with a large R. tontonteanc representing either the Colorado or Gila River, and the Mississippi River is identified as the R. de Spirito Santo. This is the only issue of this map, but Girolamo Ruscelli enlarged it for his atlas in 1561.
