False-color (CIR) composite on Landsat TM β€” band-to-color-gun mapping?
likely airborne

Band Combination 4-3-2 (color-infrared, CIR) on Landsat TM:

  • πŸŸ₯ R display gun ← Band 4 (NIR) β†’ 🌳 vegetation glows red
  • 🟩 G display gun ← Band 3 (Red)
  • 🟦 B display gun ← Band 2 (Green)

Each band feeds the next display gun up β€” one color shifted.

⚠️ On Landsat 8/9 OLI: R=B5, G=B4, B=B3.

πŸ”Ž Field check: if vegetation looks bright red, you’re looking at CIR.

False color = 4-3-2 (one higher than true color). NIR β†’ Red gun = vegetation glows BRIGHT RED. If veg is red in your image, it's CIR.
