GeoEye :The GeoEye-1 satellite sensor was successfully launched on September 6, 2008. GeoEye-1 is capable of acquiring image data at 0.46 meter panchromatic (B&W) and 1.84 meter multispectral resolution. GeoEye/GIS :GIS (GeoEye Imaging System) is a pushbroom imaging system whose basic elements are the optics subsystem (telescope assembly), the focal plane assembly (CCD detector), and the digital electronics subsystem.id:GeoEye/GIS.a |
