DigitalGlobe's CitySphere™ features 60 cm orthorectified color imagery for 200 pre-selected cities worldwide. These GIS-ready cities are available as off-the-shelf products, ready for shipment within two business days following order confirmation. Each city is a color-balanced mosaic of recent imagery and will be refreshed every year, so that all imagery contained in the updated product is no older than 24 months.
