Algeria is the largest country on the Mediterranean Sea, the second largest on the African continent after Sudan, and the eleventh-largest country in the world. The Sahara covers more than four-fifths of its territory, where the inhabitants are concentrated in oases surrounded by desert. This map offers an inset city map of Alger, including a separate inset of the metro system. It includes the area from above Seville in Southern Spain, including access points by ferry to France and Spain. The map also includes parts of Morocco, Mali, Mauritania, Niger, Libya and Tunisia. Much of Algeria is now recovering and developing into an emerging economy. The high prices of oil and gas are being used by the new government to improve the country's infrastructure and especially improve industry and agricultural land.
