Summary

• 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

• 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
