Illinois Institute of Technology hosts “An Earthly Canvas,” an exhibit of the art of satellite imagery highlighting the work of Stuart Black and UTD's own Larry Ammann

Using Earth as their canvas, they offer two differing interpretations in this emerging artform.

From this unique perspective, over 400 miles above the Earth, they challenge the notion of place and familiarity. Some of the locations will surprise you, even more will amaze you. Both artist's work is derived from digital data from satellites 438 miles (705 km) above the earth.

The digital data measures surface radiation across seven bands of the electromagnetic spectrum – three visible and four in the infrared region.

Colors are assigned to this data using complex algorithms that are designed to highlight the variety of topographic features observed. Larry's approach and interpretation is to real the unique compositions, shapes, and colors of the Earth that are hidden in the data while still retaining recognizable topographic features.

This exhibit covers a diverse selection of the earth; urban areas, deserts, rainforests, mountains, rivers, and oceans. Many of these will be familiar to you, so much so, that each image will only include either a longitude or latitude. The gallery will include a world map where you can try to locate each image, along with a key containing a description and title to help you interpret features that may serve as clues.  Can you identify all the locations?  How well do you know our Earth?  How different is their perspective high above from ours?
