Question: Which explorer accurately mapped the coasts of both the continent where the first modern greenhouses were built, and the area under which WINEP bundles the countries of Northwest Africa?

<P0-S0> Greenhouses convert solar light to heat, enabling year-round production and the growth (in enclosed environments) of specialty crops and other plants not naturally suited to the local climate. <P0-S1> The first modern greenhouses were built in Europe in the 16th century to keep exotic plants brought back from explorations abroad. <P0-S2> Primitive greenhouses were first used during Roman times to produce cucumbers year-round for the Roman emperor Tiberius. <P0-S3> Greenhouses remain an important part of horticulture today, and plastic transparent materials have also been used to similar effect in polytunnels and row covers. <SEP> <P1-S0> Approximately one third of the map survives; it shows the western coasts of Europe and North Africa and the coast of Brazil with reasonable accuracy. <P1-S1> The Piri Reis map is a world map compiled in 1513 from military intelligence by the Ottoman admiral and cartographer Piri Reis (pronounced (piɾi ɾeis)). <P1-S2> Various Atlantic islands, including the Azores and Canary Islands, are depicted, as is the mythical island of Antillia and possibly Japan. <SEP> <P2-S0> The WINEP bundles the countries of Northwest Africa together under "North Africa." <P2-S1> The Washington Institute for Near East Policy (WINEP) is a non-profit organization for research and advice on Middle Eastern policy. <P2-S2> It regards its target countries as the Middle East but adopts the convention of calling them the Near East to be in conformance with the practices of the State Department. <P2-S3> Its views are independent. <P2-S4> Details can be found in Policy Focus #65. <SEP> <P3-S0> portuguese discoveries (portuguese: descobrimentos portugueses) are the numerous territories and maritime routes discovered by the portuguese as a result of their intensive maritime exploration during the 15th and 16th centuries. <P3-S1> portuguese sailors were at the vanguard of european overseas exploration, discovering and mapping the coasts of africa, canada, asia and brazil, in what became known as the age of discovery. <P3-S2> methodical expeditions started in 1419 along west africa's coast under the sponsorship of prince henry the navigator, with bartolomeu dias reaching the cape of good hope and entering the indian ocean in 1488. ten years later, in 1498, vasco da gama led the first fleet around africa to india, arriving in calicut and starting a maritime route from portugal to india. <P3-S3> portuguese explorations then proceeded to southeast asia, where they reached japan in 1542, forty - four years after their first arrival in india. <P3-S4> in 1500, the portuguese nobleman pedro álvares cabral became the first european to discover brazil. <SEP> <P4-S0> the first country to attempt to circumnavigate africa was portugal, which had, since the early 15th century, begun to explore northern africa under henry the navigator. <P4-S1> emboldened by these early successes and eyeing a lucrative monopoly on a possible sea route to the indies the portuguese first crossed the cape of good hope in 1488 on an expedition led by bartolomeu dias. <P4-S2> just nine years later in 1497 on the orders of manuel i of portugal, four vessels under the command of navigator vasco da gama rounded the cape of good hope, continuing to the eastern coast of africa to malindi to sail across the indian ocean to calicut, on the malabar coast. <P4-S3> in south india -- the capital of the local zamorin rulers. <P4-S4> the wealth of the indies was now open for the europeans to explore; the portuguese empire was the earliest european seaborne empire to grow from the spice trade.
