Guadalcanal Island, located in the southwestern Pacific Ocean, is the largest island in the Solomon Islands. It lies 32 km north of Tulaghi Island, 54 km northeast of Malaita Island, 63 km southeast of San Cristobal Island, and 181 km south of Rennell Island. Administratively, Guadalcanal Island falls under the jurisdiction of the Solomon Islands. Its geographic coordinates range from 9°15'1"S to 9°56'47"S and 159°34'59"E to 160°50'0"E. The total area of Guadalcanal Island calculated via the Albers projection is 5358.97 km², and its coastline length calculated via the Lambert projection is 525.71 km. The city of Honiara is situated on the northern coast of the island; it serves as the capital and a major port of the Solomon Islands. An international airport, Gudalcanal Airport, is located to the east of Honiara. Guadalcanal Island has a tropical rainforest climate, with year-round high temperatures and dense forests. This dataset was compiled based on the Global Multi-Scale Coastal (Island) Shoreline Dataset (2015) derived from Google Earth remote sensing imagery, combined with relevant maps of the Solomon Islands. The dataset is stored in two formats: .kmz and .shp, consisting of 22 files with a total uncompressed size of 490 KB, and a compressed size of 135 KB when packaged into 3 files.
