Now you can be your own remote sensing platform on the cheap – in 3D! Microsoft’s Photosynth application (installs in your browser) allows anyone to combine pictures taken from any angle from the ground or kite, balloon or radio-controlled airplane- what have you- and make a geometrically-corrected aerial view or 3D virtual world. Just upload your photos! The technology is based on work by Noah Snavely (now at Cornell)- unleashing a magnificent new force on the remote sensing scene- the plain old digital camera!
