Satellite Image, Photo of George River, Quebec

George River, Quebec, Canada August 1997. The northward flowing George River is located southeast of Ungava Bay in extreme northeast Quebec. The George River winds through a glaciated wilderness that consists of low hills and a multitude of lakes (dark features of various sizes and shapes). Continental icesheets scoured the terrain thereby producing depressions that have subsequently filled with water which appear as numerous dark lakes. Shallow soils, bare rock surfaces, and year round cold temperature produce sparse vegetation throughout the region. Although rapids break the course of the George River, many adventurous canoeists have traversed the river all the way north to the estuary that empties into Ungava Bay.

Konari, Iran

The Mand River and the small town of Konari nestle in the Zagros Mountains in western Iran. This image was acquired by Landsat 7s Enhanced Thematic Mapper plus (ETM+) sensor on February 2, 2000. This is a false-color composite image made using shortwave infrared, infrared, and green wavelengths. The image has also been sharpened using the sensors panchromatic band.

Fires in Eastern Australia

These true-color Moderate Resolution Imaging Spectroradiometer (MODIS) images from late fall 2002 and early winter 2003 show fires (red dots) burning throughout eastern Australia. The whole continent has endured an especially brutal fire season as a result of a record-breaking drought.

Satellite Image, Photo of Lake Junin, Andes Mountains, Peru

Lake Junin, Andes Mountains, Peru June 1993. The dark feature in the center of the color infrared image is Lake Junin. Located at approximately 13393 feet (4082 meters) above sea level, Lake Junin is about 90 miles (145 kilometers) northeast of Lima in the Andes Mountains. Numerous erosional stream channels and deep canyons are visible at the top (northeast) of the image. The rivers drain eastward and eventually flow into the Amazon Basin of eastern Peru. Notice that there is a redder border that encircles three-quarters of the lake (except the southwest coast). This is an indication that healthy green vegetation (green, chlorophyll-bearing vegetation is portrayed as reddish hues in color infrared images) can be mapped around most of the periphery of the lake. The lake measures roughly 25 miles (40 kilometers) in length and approximately 9 miles (15 kilometers) in width. Some of the mountainous terrain immediately southwest of the lake shows an intensively folded, northwest- aligned landscape..

Tibetan Plateau, China

The Tibetan Plateau is the highest plateau in the world. The region is rimmed to the south by the Himalaya Mountains, and is dotted with fresh and salty lakes. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on May 26, 2002.
