IKONOS
IKONOS is the first very high-resolution (1-meter)
civilian sensor providing images comparable to aerial photos. The
first Ikonos satellite was lost at launching, but the second one
is still operational. The very high resolution allows to visualize
buildings, roads or even trees and is therefore very useful for
applications such as urban cartography, land use, agriculture or
natural disaster management.
