Module 2 Lab -Spot Panchromatic & SPOT Multispectral

Compare the SPOT panchromatic image and the multispectral mode display. Note any difference?

The two obvious differences are the color and resolution. The Pan image is a single band image (band 1) and the Multispectral image, like the name suggests, incorporates three spectral bands (bands 4,3,2). The Panchromatic image is at 10 meter ground resolution and the Multispectral image has a resolution of 20 meters. The displays also differ in their pixels per line values. Spot Panchromatic has 6,000 pixels per line and the Multispectral has 3000. The Panchromatic displays higher resolution and pixels per line producing a sharper image.

CIR photography

What problems might you infer or identify in using this type of photography?

A major problem with CIR photography would be misinterpretation of objects or features. CIR photography requires a bit more color and feature interpretation training (vs.Natural). CIR 's uses in distinguishing vegetation types and vegetation health are fantastic, however, distinguishing among these vegetation types requires a trained eye. CIR is great at highlighting the contrasts between natural and unnatural (man-made) features. One might easily identify a common feature (i.e. golf course, baseball field) in the CIR image, but, be unable to interpret the color value (i.e. red vs. green).
