Standard Satellite Imagery

Resources

For the experienced user, we provide our most flexible product, Standard Imagery. Each Standard Image is radiometrically calibrated, corrected for sensor and platform-induced distortions and mapped to a cartographic projection. Standard Images are well suited for visual analysis image classification and as a backdrop for GIS and mapping applications that require a modest level of accuracy. More sophisticated users can start with our Standard Imagery, apply their own Digital Elevation data and ground control points and create very accurate orthorectified imagery.

Deliverables

Standard Imagery can be acquired directly from the DigitalGlobe archive or you can submit a new collection request. Standard Imagery is ordered by area, with a minimum purchase of 25 km² (~10 mi²) for archive orders. For tasking, the minimum area for ordering is 25 km² (~10 mi²), but minimum pricing rules apply, depending on the tasking level selected. If your order crosses more than one strip, one standard imagery product per scene is delivered.

Products are delivered on your choice of standard digital media with Image Support Data files including image metadata.

* Distribution and use of imagery at better than .50 m GSD pan and 2.0 m GSD multispectral is subject to prior approval by the U.S. Government.
