King William Island is located in North America, within the Arctic Circle, and belongs to the Canadian Arctic Archipelago. It lies between Victoria Island and the Boothia Peninsula, 85 km away from Victoria Island; 155 km north of Prince of Wales Island; to the south, it faces the North American continent (Adelaide Peninsula) across the St. Roch Strait and Simpson Strait, with the closest point being merely 3.3 km. King William Island was discovered by Commander James Ross in 1830, and was named after the then-reigning British monarch William IV. Administratively, King William Island falls under the jurisdiction of Nunavut, Canada. Its geographic coordinates are: 69°54′22″N - 68°27′12″N, 99°32′48″W - 95°09′25″W. The total area of King William Island is 13259.59 km², with a total coastline length of 1555.35 km. The island has a flat terrain, with countless small lakes scattered across its surface. Gjoa Haven, located on the southeast side of the island, is the primary settlement on King William Island. There is an airport northeast of Gjoa Haven. This dataset was compiled based on the Google Earth remote sensing imagery-derived global multi-scale sea-land (island) coastline dataset (2015), combined with relevant Canadian maps. The dataset comprises 24 data files stored in .kmz and .shp formats, with an uncompressed total size of 2.98 MB (compressed into 3 data files with a size of 2.06 MB).
