Summary
• Better means up-to-date and most in-depth historical imagery for projects and analysis
• Better ability in processing improvements from consistency within the imagery, additional analysis of the pixels with the extra bands and better confidence with results
• Better means further analysis from the pixels, and better confidence in the results
• Better means confidence that they can rely on DigitalGlobe as the one source for all projects
• Faster means using the most current, view to show exact ground-truth and the ability to react, make decisions and/or change direction faster minimizing any business or environmental impacts
• Faster means detecting change in a matter of days – not months or quarterly.
• Faster means collecting broad extensive regions, countries and metropolitan areas for: basemaps on portals, navigation/mobile devices and coverage of global enterprises assets
• Faster means always having a competitive edge over other satellite imagery or free imagery sources
