panchromatic, multi-spectral and colour
products enable superior image classification
and analysis based on discrete spectral
bands and 11-bit information depth. Typically,
customers utilize 4-band imagery for image
classification and analysis, while Panchromatic
and Pan-sharpened imagery is used for visual
analysis and for GIS and Mapping applications
that support the standard GeoTIFF format.

Imagery products are offered at three levels:
- Basic

- Standard
and Standard Ortho-ready Imagery

Panchromatic imagery is collected in 11-bit
format (2048 gray levels) and delivered
in 16 bit format for superior image interpretation
(shadow detail, etc.), or 8-bit format
(256 gray levels) supported by GIS and
mapping applications. Four-band multi-spectral
imagery consists of blue, green, red and
near-infrared bands, delivered in 16-bit
and 8-bit formats. In addition, Pan and
