DEFINITION: Basic Product
Options
- Panchromatic: A single
layered image product, (i.e.: greyscale), acquired by a
sensor with a broad range of radiometric sensitivity through the visible and
near infrared ranges. Its relative coarse radiometric resolution enables a small Ground Sample Distance (GSD),
or fine spatial resolution, thus producing "high-res" imagery with small
pixels.
- Multi-spectral: A
multi layered stack of images consisting of 4 , 5, or more layers acquired
simultaneously by multiple sensors each with sensitivity for an exclusive
range of the light spectrum. Its relatively fine radiometric resolution requires a
relatively large GSD producing a relatively coarse spatial resolution.
- Bundle: Two images:
one containing
the panchromatic data layer and the other containing a stack of the multi-spectral data layers.
All data are acquired simultaneously.
- Natural Color: A
three
layered typically pan-sharpened color image produced by fusing panchromatic and
multi-spectral data layers to achieve naturally colored imagery.
- Color Infrared: A
three layered typically pan-sharpened color image produced by fusing
panchromatic and multi-spectral data layers for enhanced vegetation based
mapping.
- Stereo: A stereo
pair of satellite or aerial imagery is acquired with tolerances for specific
angles of incidence for the sole purpose of geometric feature
extraction for surface model construction.
- Aerial: Please specify:
ortho-metric or panoramic.
- Topography: Xeric
surface models and elevation contours.
- Bathymetry:
Sub-marine surface models and elevation contours.
- Geophysical:
Typically Petroleum or Mineral exploration data.
