Basic Imagery
For users having advanced image processing capabilities
Basic Imagery products are designed for users having advanced image processing capabilities.
DigitalGlobe supplies camera model information with each Basic Imagery product to permit users to perform sophisticated photogrammetric processing such as orthorectification and three dimensional feature extraction. Basic Imagery is the least processed image product with corrections for radiometric distortions and adjustments for internal sensor geometry, optical, and sensor distortions have been performed on each scene ordered.
Features
| Features | Benefits |
|---|---|
| Spacecraft telemetry and camera model supplied with satellite imagery | Perform your own photogrammetric processing on raw data to produce orthorectified imagery and first generation basemaps |
High resolution
|
Identify features, create maps, and detect changes from recent global imagery at the highest resolution possible from commercial imaging satellites |
Large image swath collection size
|
Map large areas faster with fewer files to manage and process |
High radiometric response
|
Improve feature classification and identification in dark or bright areas such as building shadows or snow and perform more flexible image enhancement |
Open systems
|
Get your high-resolution satellite orthoimagery project up and running quickly and easily using your existing commercial software |
*Attained using supplied Image Support Data files, viewing geometry, and terrain distortions.

A - Pixel resolution varies across the image due to off-nadir viewing angle. Pixels closest to nadir have a better resolution than those farthest from nadir. Resolution varying from nadir up to 25° are reported here. DigitalGlobe can collect targets up to 45°, upon request.
B - Scene dimensions vary due to off-nadir viewing angle. Scene sizes up to 25° are shown, but DigitalGlobe can collect targets up to 45°, upon request.
C - Attained using supplied Image Support Data files and exclusive of sensor, viewing geometry and terrain distortions.
* - Attained using supplied Image Support Data files and exclusive of sensor, viewing geometry and terrain distortions.
Delivery
Basic Imagery can be acquired directly from the DigitalGlobe archive, or by submitting a new collection request. Basic Imagery available by scene, from a minimum purchase of a single scene up to a maximum of 10,000 km2 per order. Products are delivered on your choice of standard digital media, including all the Image Support Data files needed for photogrammetric processing, including attitude and ephemeris data, geometric calibration, camera model, image metadata, radiometric data, and rational functions.
