Image Caption: NM21-774-044 Pittsburgh, Pennsylvania Spring-Summer 1996
The built-up metropolitan area that is the city of Pittsburgh is difficult to identify in this image because of the small scale, low spatial resolution, and in fact that most of the residential subdivisions contain vegetative cover that at least partially obscures the urban sprawl that surrounds the downtown core. Downtown Pittsburgh, or the central business district, is located at the apex of the influence of the southwest flowing Allegheny River and the northerly flowing Monongahela River (right center). These two rivers merge to become the Ohio River. Parts of several highway thoroughfares can be traced across the hilly terrain. The light colored, linear roadways include Interstate Highway 279 (left center); Interstate Highway 379 (lower left); Us highway 30 (left center); and state Highway 51 (towards upper left center). Residential development and highway orientation patterns have been greatly controlled by the local topography. The darker features of the image show the distribution of the more densely wooded terrain.
