This is a crop of a much larger photo of downtown Tampa at the DigitalGlobe site, a relative new high resolution satellite image site. Here is how they describe the photo:

“This natural color pan-sharpened image was created by using QuickBird 2.44-meter multispectral image data (red, green, and blue bands) to colorize the QuickBird panchromatic image data. This image chip shows an overview of downtown Tampa, Florida.”
