in general the countries surrounding the Mediterranean. The word portolan is from the Italian. They were intended for navigation from port to port, rather than the wide ocean. Columbus probably had a ('appropriated') fragment of a Portuguese one - originally from Turkey - that he used in his Spanish-sponsored voyage to the new world.
Assuming the map is of the known world, medieval maps were usually centered on Jerusalem. Sometimes they were centered on Rome. Portolan charts were sometimes based on a projectioncentering on Alexandria, and this was true even if Alexandria was not on the map.
An unconfirmed airport is an airport that may or may not still be open for public use, but is still shown on charts for navigation purposes or for emergency use.

During the Age of Exploration, Iberian sailors made significant advancements in navigation and ship design. The development of the caravel, a small, highly maneuverable ship, allowed for exploration along Africa's coast and across the Atlantic. Innovations like the astrolabe and quadrant improved celestial navigation, enabling sailors to determine their latitude at sea more accurately. Additionally, the use of detailed maps and charts, such as the portolan charts, facilitated more precise navigation and exploration.
