The artwork Arrivederci Roma by Chiara Solimini and Fabio Pacifici, based on a satellite image, has been selected for the traveling gallery show that opened at the Denver (Colorado, U.S.A.) Museum of Nature & Science in January 2007.
Only the top thirty of several hundred entries were selected for the show.
In addition, the work appears in the Art in Science | Science in Art online gallery.

The high resolution satellite images have been processed with neural network algorithms to extract change detection maps of urban areas. This image is a step in the classification method and represents a subarea of the city of Rome acquired by the QuickBird satellite. Each pixel of the image is a vector whose components are the logarithm of the ratios of the multispectral bands belonging to the two multitemporal images from 2002 and 2003. The image is also the input of a neural network that is trained with the above pixel values. With this method the changes occurring in an urban area, such as new buildings and roads constructed between the two acquisition dates, and also changed vegetated areas, have been detected.

The artwork is being exhibited at the New York Hall of Science till June 2009.
