Satellite Image, Photo of the Tempisque River Basin, Costa Rica

Tempisque River Basin, Costa Rica January 1997. The broadest part of the Nicoya Peninsula where it attaches to the mainland is featured in this color infrared picture (green vegetation is presented in red colors) of the northwest coast of Costa Rica. This region has been developed by a series of up-faulted blocks creating a mountainous peninsula, with many indented shorelines, and a steep, rocky coastline. The lowland area immediately northeast of the peninsula is the Tempisque River Basin. The main channel of the river can be traced across the image (mainly as a thin, dark line) as the river first flows south and then makes a turn southeast, finally emptying into the Gulf of Nicoya (off the right edge of the picture). The Tempisque River and its tributaries have produced an extensive lowland alluvial plain. Large field patterns are visible on the higher elevations of this fertile plain, especially on the northeast side of the river, where tropical lowland agriculture flourishes-including ranching and plantation activities. The darker areas near the delta and mouth of the Tempisque River shows an extensive area of low-lying swamps and lagoons, many of which are saline in nature.

Satellite Image, Photo of Nicoya Gulf, Peninsula, Costa Rica

Nicoya Gulf, Peninsula, Costa Rica January 1997. The southern end of the mountainous Nicoya Peninsula extends southeasterly separating the waters of the Pacific Ocean from the Gulf of Nicoya. The color infrared image helps to document the numerous vegetated hills and valleys (red colors represent green plants) both on the peninsula as well as on the mainland. The deeper reds tend to show either dense stands of rainforest or in the coastal zone, they represent mangrove forests. The small estuary of the Rio Grande de Tarcoles is barely discernible near the upper right edge (southeast corner) of the image. Chira Island is the large island in the Gulf of Nicoya.

Satellite Image, Photo of Costa Rica´s Caribbean Coastal Plain

Original Caption Released with Image: This perspective view shows the Caribbean coastal plain of Costa Rica, with the Cordillera Central rising in the background and the Pacific Ocean in the distance. The prominent river in the center of the image is the Rio Sucio, which merges with the Rio Sarapiqui at the bottom of the image and eventually joins with Rio San Juan on the Nicaragua border..

Satellite Image, Photo of Northern Nicoya Peninsula, Costa Rica

Nicoya Peninsula, Costa Rica January 1997. Missing only the southern end of the Nicoya Peninsula, this color infrared image includes most of the low mountainous terrain that makes up this rugged peninsula. Since this picture is a color infrared image, the darker reds indicate an abundance of vegetative cover (in some areas even a rainforest environment exists) over the landscape. The deep reds near the mouth of the Tempisque River, shows an extensive region of low-lying swamplands and tidal marshes. Some of the darker areas around the Gulf of Nicoya include large stands of mangrove forests. The highly reflective areas and the large angular-looking field patterns are human induced development activities-either mining or agricultural endeavors. The coastline that faces the Pacific Ocean is irregular with numerous small bays and steeply sloping cliffs. Chira Island is the large island in the Gulf of Nicoya.
