Washington, D.C. ? The Pentagon has banned Google Earth teams from making detailed street-level video maps of U.S. military bases.

A message sent to all Defense Department bases and installations around the country late last week told officials to not allow the popular mapping Web site from taking panoramic views inside the facilities.

Michael Kucharek, spokesman for U.S. Northern Command, told The Associated Press on Thursday that the decision was made after crews were allowed access to at least one base. He said military officials were concerned that allowing the 360-degree, street-level video could provide sensitive information to potential adversaries and endanger base personnel.

His comments came just a few days after published reports suggested that protesters used Google Earth to help plot their access to the roof of the Parliament building in London.
