            "description": "These scenes shows Landsat Thematic Mapper data of the cities of Oakland and Berkeley, as well as the San Francisco Bay Area. The first image, which is predominately brown in color, is a 'natural color' image which uses the Thematic Mapper bands 3, 2, and 1 displayed as red, green, and blue respectively. This yields a color scheme approximately the same as those seen by the human eye. The other two scenes use data from the infrared portions of the electromagnetic spectrum to maximize the range of wavelengths shown. These images use the shortwave infrared (TM band 5), infrared (TM band 4), and visible green (TM band 2) channels. Digital elevation data was used in the two city scenes to create three dimensional terrain, which is vertically exaggerated by a factor of three to show the relief of the land. The city in the foreground and slightly to the left is Oakland, with Alameda on the island seperated from Oakland by the narrow strip of water. The island south (left) of Alameda is filled land on which the Oakland International Airport has been built. The Bay Bridge carries Interstate 80 across the Bay and into downtown San Francisco to the right of the image center. Berkeley sits between the hills and bay to the north (right) of the Bay Bridge. San Francisco, Angel Island, Tiburon, Marin County, and the Golden Gate are all visible on the far side of the bay. The strong brown/gray tone of the natural color image is a result of the data being taken during the early autumn when ground cover is very dry and the land tends to appear somewhat barren. In the TM 542 scenes, barren exposed land appears red to pink, vegetation appears green, and water is dark blue. || ",

            "description": "These images are compressed versions of high definition television (HDTV) images showing how Landsat data, which spans a very broad swatch of the electromagnetic spectrum, can be turned into images. The TIFF versions of these images are full resolution HDTV frames (1920 x 1080). All images have the HDTV standard aspect ratio (16:9).The Thematic Mapper (TM) on Landsat 4 and 5 observes reflected sunlight from the Earth all the way from blue in the visible part of the electromagnetic spectrum to shortwave infrared well beyond the ability of the human eye to percieve. The TM instrument also can observe infrared radiation actively emitted by the Earth from thermal infrared radiation. Landsat 7 carries an improved version of the TM instrument, called ETM+. In addition to 7 channels of spectral data collected by the older TM instruments, ETM+ can observe in a special panchromatic band spanning the entire visible spectrum at twice the resolution of the TM bands (15 meter resolution instead of 30 meters). The ETM+ also has a major improvement in the resolution of the thermal band (60 meter resolution instead of 160 meters).A standard way to create images from raw Landsat TM and ETM+ data is to display a single band as a primary color, then combine different bands to create a full color image. Images shown here demonstrate combining three bands to make a color image using TM bands 5, 4, and 2, which covers a very broad range of the TM's spectral coverage. It is also shown in combination with a digital elevation model. Terrain data is shown with vertical features exaggerated by a factor of three to emphasize details. || ",

            "description": "These scenes show Portland, Oregon and the countryside around it as seen by the Landsat Thematic Mapper (TM) instrument. Portland sits on the Willamette River south of its confluence with the Columbia River. The city sits very close to several mountains in the Cascade Range, including Mt. Hood, Mt. Adams, and Mt. St. Helens. The terrain of the area is also shown exaggerated by a factor of two to emphasis terrain features such as the mountains and the Columbia Gorge just north of Mt. Hood and south of Mt. Adams.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 gray or black. The natural color images combine TM bands 3, 2, and 1 and map them to red, green, and blue, respectively. || ",
