Visible as a small white area near the shores of the island of Borneo is Pontianak, the capital of the Indonesian province of West Kalimantan. It is located almost precisely on the equator, hence it is widely known as Kota Khatulistiwa (Equator City). As can be observed in this orthorectified wide-swath ASAR image, the land near the city is mostly flat, while some hills are visible to the north and northeast.
Pontianak is a medium-size industrial city that occupies an area of 107.82 km² in the delta of the Kapuas River. The Kapuas River is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At 1,143 kilometers (710 mi) in length, it is the longest river of Indonesia and one of the world’s longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta.
