From Wired,
This bird's-eye view of Kutztown University in Pennsylvania was the first image ever seen by the GeoEye-1, the world's highest-resolution commercial satellite sponsored by Google, when it opened its camera door earlier this week.
The 4,300-pound satellite collected the image at noon EDT on Oct. 7 while moving from the north pole to the south pole in a 423-mile-high orbit at 17,000 miles per hour, or 4.5 miles per second. The spacecraft can take photos at a resolution of up to 41 cm -- close enough to zoom in on the home plate of a baseball diamond, according to Mark Brender, GeoEye's vice president of communications and marketing.
Since around the late 70s, the military has used high-resolution spy satellites capable of reading newspaper headlines in Red Square. But only in recent years the technology became available to the public and businesses while concurrently making dramatic strides in coverage and resolution. For example, when Google Earth launched in 2004, its imagery was low-res and spotty. But by March 2006, a third of the world population could get a bird's-eye view of their own homes in high resolution.
There's one catch for Google: While the GeoEye-1 will provide imagery to the NGA at the maximum resolution of 43 cm, Google will only receive images at a 50-cm resolution because of a government restriction, Brender explained. However, Google's partnership with GeoEye is exclusive, meaning the search-engine giant will be the only online mapping site using the satellite's photos.
A second satellite, GeoEye-2, slated to launch in 2011 or 2012, will have a resolution of 25 cm, company representatives promised. However, Google's satellite imagery will not likely get more detailed because of the 50-cm regulation.
The two interesting things I took from this:
1. What the hell does Google not have it's hands in and what do they do that doesn't work?
2. So the government has had and been using these high resolution satellites for almost 40 years, what kind of crazy technology do they have now in 2008?
....this provides me with somewhat of a segue to a post to come, check back soon.
