Prompt
[MANDATORY] SPOT — nation, orbit altitude, band/resolution, notable feature.
Plain English answer (default view) — what you'd actually write on the test
**SPOT** is the French Earth-observation satellite series ("Satellite Pour l'Observation de la Terre"). Think of it as a smaller Landsat with **two cool tricks**: - **Tilting cameras** — the sensor can swing sideways to image areas off the satellite's path, which gets you stereo pairs (3D!) and faster revisit. - **Finer detail** — 10 m panchromatic vs. Landsat's 30 m. **Quirk to remember:** SPOT 1, 2, and 3 have **no blue band** — only green, red, and NIR. So you can't make a natural-color image from those satellites. Series ran from 1986 (SPOT 1) to current SPOT 6/7.
🔬 Technical version / model bullets (revealed on click) — one bullet per line
French/European series from CNES; SPOT = Satellite Pour l'Observation de la Terre. SPOT 1–3 altitude **832 km** sun-synchronous; SPOT 6/7 altitude 694 km. HRV bands: green, red, NIR (+SWIR on SPOT-4+); 10 m pan / 20 m MS. Off-nadir pointing (±27°) → stereo imagery + shorter revisit (1–4 days).
