Last night I was going through one of my external hard drives and rediscovered a cache of “old” satellite imagery. I rarely publish any entries that use satellite imagery due to copyright issues because, generally speaking, the company that owns the satellite also owns all the pixels and this prevents me from legally creating derivative works. Today, however, I decided to test the boundaries with this legacy satellite imagery of the Pentagon and feel that this creation is protected under the fair use doctrine of US copyright law. You can always contact GeoEye if you are interested in purchasing satellite imagery from the IKONOS satellite.
The Animated GIF below features 9 frames consisting of 7 satellite images from the IKONOS Satellite (2001-2002) and two public domain aerial photographs from the USGS (2002 & 2005). It begins with satellite imagery taken four days before 9/11/01 and ends with a USGS aerial photograph taken in September 2005. The frames in between show the aftermath and the subsequent rebuilding of the Pentagon. I did my best to line up the building in my image editing program, but it’s not 100% perfect due to the angle in which some of the imagery was taken.
I have chosen to place the The Pentagon Timelapse Animated GIF “below the fold” so that visitors to the front page of this website are not downloading the somewhat large file. Please be patient while it downloads……
