Up a Creek

July 2005

Map illustration to accompany an article about an expedition down the Saganavirktok River in Alaska, mounted by a science writer and several climate experts, to observe the effects of global climate change.

I created these pieces by taking imagery for the region from several Landsat 7 wavelength bands, merging them to create a synthetic true-color image, and then draping the resulting composites over a three-dimensional USGS DEM terrain model.

The illustration had to be sized so as to span eight pages of the magazine at high resolution. The resulting composite file was immense - approx 2GB. But it did allow for detailed usage in the layout, as shown on the opening spread here. (Art direction by Jason Lancaster)
