The launch of the GeoEye-1 satellite by GeoEye (formerly Orbital Imaging Corporation or ORBIMAGE), a commercial satellite imagery company based in Dulles, Virginia, marks the coming of higher resolution maps in the internet.
Until now there has only been maps of commercial imagery 60 cm, but with GeoEye-1, google will get details of objects of size 50 cm (though the satellite can get 41 cm images). Thus we will be getting clearer maps of the places around us.
