The images on the Channel Navigator website are from the US Geological Survey's three-part interpretive series, Earth as Art. The artists of these collections in the EROS (Earth Resources Observation and Science) Image Gallery are three sensors aboard NASA satellites orbiting the Earth: Landsat 7, ASTER and MODIS.

These images graphically illustrate the notion of "channel" as a global connector and medium of communication. Information technology has aptly chosen the channel as its sales and service medium, connecting products and services to clients through local and far-reaching networks of value-added resellers (VARs); and connecting clients back to training and support through the VAR channels.

Below are descriptions of the channel systems depicted throughout Channel Navigator [click on thumbnail for large image]:

DELTA AT THE NORTH SEA, THE NETHERLANDS - Along the coast of the Netherlands, sediment-laden rivers have created a delta of islands and waterways between coastal dunes. After spring tides devastated this region in 1953, the Dutch built dikes, canals, dams, bridges, and locks to hold back the North Sea.

Coursing through parched, landlocked Mali in Western Africa, the Niger River flows north through an ancient sand sea before turning sharply east to skirt the edge of the dune-striped Sahara. At the confluence of the Bani and Niger rivers is an island delta complete with narrows, twisting waterways, lagoons, and tiny islands.

Like a many-faceted jewel fashioned in an indigo setting, the Shetland Islands lie 210 km north of the Scottish mainland in the North Atlantic Ocean. Despite their 60 degree north latitude, the Shetlands enjoy a relatively temperate climate thanks to the warming influence of the Gulf Stream.

Vivid colors and bizarre shapes come together in an image that could be an imaginative illustration for a fantasy story. This labyrinth of exotic features is present along the edge of Russia's Chaunskaya Bay (vivid blue half circle) in northeastern Siberia. Two major rivers, the Chaun and Palyavaam, flow into the bay, which in turn opens into the Arctic Ocean. Ribbon lakes and bogs are present throughout the area, created by depressions left by receding glaciers.

After beginning in northern British Columbia and flowing through Yukon in Canada, the Yukon River crosses Alaska, USA, before emptying into the Bering Sea. Countless lakes, sloughs, and ponds are scattered throughout this scene of the Yukon Delta. The river's sinuous, branching waterways seem like blood vessels branching out to enclose an organ. It is one of the largest river deltas in the world, and currently (2010) protected as part of the Yukon Delta National Wildlife Refuge.
