CitySphere
DigitalGlobe’s CitySphereTM product features 60 cm or better orthorectified color imagery for 300 pre-selected cities worldwide. These GIS ready cities are available as off the shelf products and ready for immediate delivery. Each city is comprised of recent imagery, with initial imagery no older than 2006. Going forward, each city will be completely refreshed, so that no pixels are delivered twice. The resolution and accuracy of CitySphere make it ideal for use as a basemap in your GIS, personal navigation mapping and mobile device applications, as well as many other location based services.
