Instead of just the straight-down views that distant satellites
gather, a small company called Pictometry International has developed
an oblique-imaging, geo-spatial system to snap vast swaths of America’s
varied landscape at a 40-degree angle from a few thousand feet in the
air.
At the click of a mouse, its unique measuring software can dissect
the longitude, latitude, elevation and precise dimensions of every
discernible landmark, from fire hydrants in Chicago to lilac trees in
Rochester to the levees of New Orleans before and after Hurricane
Katrina.
