Fires in Canada's Prairie Provinces
In the Alberta (left), Saskatchewan (center), and Manitoba (right) provinces of Canada, several prairie fires were burning on May 20, 2002. This image, including fire detections (red outlines), was made by the Moderate Resolution Imaging Spectroradiometer (MODIS). In Alberta, at upper left of the image, it appears that fires are also burning in the boreal forest, the evergreen-dominated forest to the south of the Arctic tundra. Dotted across the landscape are numerous frozen lakes, carved by glaciers millennia ago. The largest lake in the image, at far right, is Lake Winnipeg. Please note that the high-resolution scene provided here is 500 meters per pixel. For a copy of this scene at the sensors fullest resolution, visit the MODIS Rapidfire site.

Satellite Image, Photo of Yguazu River Reservoir, Paraguay
Yguazu River Reservoir, Paraguay Winter/Spring 1997 The light colors of the overall picture indicates that most of the landscape in this region of southeast Paraguay has been cleared of trees in favor of intensive agricultural activities. Most of the croplands are used to grow cotton and soybeans, while pasture grasses are used to raise cattle. This region of Paraguay, known as the Paranena, is a mixture of rolling hills, plateaus, and broad valleys. The dark, irregular shaped feature in the middle of the image is a reservoir created by building a dam on the Rio Yguazu (dam is on eastern end of the reservoir). Several small, forested areas are visible north and south of the Reservoir (uniform dark green patches). These forests occur mainly along the river valleys and wetlands of the Rio Monday (south) and Rio Acaray (north of the reservoir)..
