Korangi (or Korangi Town) is part of the Karachi metropolitan area of coastal Pakistan. This astronaut photograph from the International Space Station highlights the contrast between the highly urbanized and industrialized Korangi area (image top and image right) to dense green mangrove forests and waterways of the Indus River Delta to the south (image bottom and image left). Away from the river delta, vegetation cover reduces rapidly to the northeast (image top right).
To the north and west, Korangi Town is bordered by the Malir River, one of two rivers (the other being the Lyari River, not shown) that pass through the Karachi metropolitan area. The river course of the Malir is marked by green riparian vegetation, which stands out vividly from orbit against the surrounding gray to tan urban areas.
One of the largest industrial areas in Pakistan is located in Korangi (known as the Korangi Industrial Area, or KIA) - this region is visible at image center, and is marked by large buildings and lots, many having large white-roofed structures. A conspicuously dark region to the right of image center marks the location of steel works; while bare soil and built materials are present, significant vegetation cover also contributes to the dark tone. In addition to steel, the KIA also includes textile, pharmaceutical, automobile, chemical, and flour industry facilities.
