What’s inside
Six topics, from the first look at a satellite image to working with the data in your own pipelines.
[ 3.1 ]
Reading satellite imagery
How to read an optical image from orbit: what is in the frame, at what scale, and how it was taken.
OPTICAL · VHR
[ 3.2 ]
Spectral bands
Visual, near infrared and short-wave infrared, and what each shows of vegetation, water, fire and change.

[ 3.3 ]
Resolution
Ground resolution per pixel, and what 0.5 to 1 metre makes visible and countable.
GSD · 0.5–1 M PER PIXEL
[ 3.4 ]
Revisit and orbits
How a constellation turns single passes into daily coverage, and what revisit means for monitoring.
ORBIT · REVISIT
