These scenes show the city of Philadelphia as seen by the Landsat Thematic Mapper (TM) instrument. The river running through the city is the Delaware which defines the boundary between New Jersey and Pennsylvania. In the larger city area image, north is approximately up. The river runs south. Just near the top of the image, upstream of the city and where the Delaware River turns west is the New Jersey city of Trenton. The shortwave infrared (TM band 5), infrared (TM band 4), and visible green (TM band 2) channels are displayed in the images as red, green, and blue respectively. In this combination, barren and-or recently cultivated land appears red to pink, vegetation appears green, water is dark blue, and artificial structures of concrete and asphalt appear dark grey or black.
