**Description**
Satellite imaging is the satellite’s capability to take photographs of the Earth and other Planetary bodies at high resolutions. Satellite imaging provides accurate data and precise time for an up to date image of the particular object.

**Applications**
Satellite images have many applications in agriculture, geology, forestry, biodiversity conservation, regional planning, education, intelligence and warfare. Homeland security or other military groups may use satellite imagery to ensure that nuclear missiles treaties have not been violated and to ensure that their data is current and up to speed. Corporations such as GeoEye and TerraServer offer high resolution satellite imagery to the public; however these sites require memberships and fees.

GeoEye
GeoEye's GeoEye-1 satellite was launched on September 6, 2008. The GeoEye-1 satellite has the highest resolution of any commercial imaging system. It can collect images with a ground resolution of 0.41 meters in the panchromatic or black and white mode. While the satellite will be able to collect imagery at 0.41 meters, GeoEye's has an operating license from the U.S. Government which, requires re-sampling the imagery to 0.5 meters for all customers not explicitly granted a waiver by the U.S. Government.

DigitalGlobe
Before the launch of GeoEye-1, DigitalGlobe's WorldView-1 satellite provided the world's highest resolution commercial satellite imagery. The 50 cm resolution of WorldView-1's allows the satellite to distinguish between objects on the ground that are at least 50 cm apart.  <span style="font-size: 110%; font-family: Arial,Helvetica,sans-serif;">   **Related Links**
