STS073-741-066 Greater Philadelphia Area, Pennsylvania October 1995 The physical setting of the metropolitan area of greater Philadelphia and its environs (center of the image) is visible in this northeast-looking color infrared view. Camden, New Jersey, a much smaller industrial city located on the east bank of the Delaware River, is opposite the central business district of Philadelphia. The Schuylkill River, a tributary of the Delaware River, is the thin, dark line that skirts the southern edge of downtown Philadelphia and heads northwest towards Reading, Pennsylvania. The runway (linear, white-looking feature immediately south of Philadelphia on the west side of the Delaware River) of the Philadelphia International Airport is visible. The deeper red colors both in Pennsylvania and New Jersey show the extent of the forested lands.
