South Korea Launches Spy Satellite

I wonder if it is at least as good as Google Earth?:

South Korea sent a satellite into space on Friday primarily for geographical surveys but also for possibly spying on North Korea, which raised regional security concerns by launching missiles earlier this month.

The 900-kg (2000 lb) Arirang-2 satellite, launched in Russia, can take high-resolution pictures of the earth’s surface, a government agency said. Experts said it would be the country’s most advanced surveillance satellite.

“The high-definition MSC (multi-spectral camera) will be able to give real-time visual data on North Korea’s missile launch preparations or military activities, which would be otherwise unavailable,” South Korea’s Overseas Information Service said.

At present, South Korea mostly relies on U.S. spy satellites and planes for aerial reconnaissance of North Korea.
