Normally,<br /><br />If public satellite photos are over areas that are classified, the imaging area is not available for publication. The images are just not there. The government get's really sticky about that...<br /><br />I wouldn't think that they would place "markers" all over the map to show "Important classified stuff exists right under this marker at the corner of John's and Trade streets." The image of that area, at the selected resolution, would not exist. ie: Not available.<br /><br />I've looked at Google's imagery and classified sites that I am familiar with are under the "image not available" category. ie: Google doesn't use opaque markers to mask them. They just don't publish the images.<br /><br />Now, if someone, somewhere, had modified contracts that said, for instance, all powerhouses, telephone exchanges, satellite nodes, military recruiting facilities and National Guard muster points, were to be blocked from all publically available satellite imagery due to the concerns brought about by 9/11.... it <b>might</b> be feasible that they would put opaques over existing, already publically available images. I haven't checked any though. I'd recommend taking a look at facilities you are familiar with that would fall under these guidelines. If you find markers, then you may have your answer.<br /><br />Personally, I like the original explanation.
