Remote sensing has been used mostly to produce analyses on different aspects and phenomena concerning territory. The approach is not different from the one employed when analysing maps in the sense that analysis depends on the nature of data, maps and satellite images being two different sources of spatial data. Obviously, analysis based on cartographic data is different from the one based on s...

On the old highway maps of America, the main routes were red and the back roads blue. Now even the colors are changing. But in those brevities just before dawn and a little after dusk—times neither day nor night—the old roads return to the sky some of its color.

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...
