2. Cost and Future Plans... Pricing per square kilometer:
Product Type: Panchromatic Only or Basic Stereo- Pan Only
Image Library (Archive) : $14 (Pan) or $28 (Stereo)
Select Tasking (New) : $20 (Pan) or $40 (Stereo)
Minimum order area for archive imagery (if available) = 25 sq. km.
Minimum order cost for new “Select Tasking” collection = $1,800 USD
There is a 210 sq. km minimum order area for all “Stereo” orders.
Future Plans:
DigitalGlobe is the only company operating a constellation of sub-meter commercial imaging satellites and in 2008 WorldView-2 provided eight bands of multi-spectral data for life-like true color imagery. Which complements the very high resolution panchromatic images from WorldView-1.
