An anonymous reader writes "Vice Adm. Robert Murrett, director of the National Geospatial-Intelligence Agency, says that the increasing availability of commercial satellite photos may require the government to restrict distribution. 'I could certainly foresee circumstances in which we would not want imagery to be openly disseminated of a sensitive site of any type, whether it is here or overseas,' he said. This would include imagery on Web sites such as Google Earth, because the companies that supply the photos get help from the NGIA with launches." I had never heard of this particular intelligence agency. During the early months of the invasion of Afghanistan they bought up all satellite imagery over that country, worldwide, in a tactic later dubbed "checkbook shutter control."
