Based on the Google Earth Images in 2015, the coastline data of the Sumatera island has been developed. The data shows that Sumatera island is located from 55o63＇4.83〃 to 53o92＇4.67〃N and 95o11＇37.64〃E to 106o5＇47.22〃E; the area of island is 428479.63 km2 and the total length of the coast lines is 15320.39 km. It is obviously that the Sumatera Island is the sixth largest island in the world. The maximum length is 1720km from north (5o39’32〃N) to south (5o54’32〃S) and its maximum width is 408 km from west (100o24’3.68〃E) to east (103o44’10.15〃E).

Bukit Barisan at 3800 meters above sea level and covering nearly 1700 km. The equator is across the island and the climate of the Sumatera is the tropical rainforest. The temperature is no significant difference among regions, but there are significant differences in rainfall. Annual precipitation of the west coast is 3000 mm, the mountain area up to 4500-6000 mm, east of the mountains is 2000-3000 mm and the north and south ends of the island is 1500-1700 mm.
