Sentinel vs Landsat vs Planet vs Maxar: earth observation platforms for climate analytics compared
Compares major earth observation platforms for climate use cases: Sentinel-2 (10 m, 5-day revisit, free), Landsat 9 (30 m, 16-day revisit, free), Planet (3–5 m daily, $5–15K/yr), and Maxar (30 cm, tasked, $15–25/km²). Evaluates spectral bands, cloud penetration, API access, and suitability for deforestation, methane, and urban heat island monitoring.
