Ground Truth

Forty years of Earth, watched without blinking, and measured.

Since the 1980s, satellites have imaged the whole planet on a loop. That unbroken record lets you compress four decades of change into a few seconds, and pull the economic signal straight out of the pixels. Six places, six kinds of change. Scroll.

The Planet difference

At three metres

Landsat · 30 mPlanet · 3 m

Illegal gold mining in Madre de Dios, Peru: rainforest stripped to bare earth and pocked with mercury ponds. The same place at Landsat's 30 m and Planet's 3 m. Drag to compare.

What it's worthGold prices drive the digging; at 3 m, daily, the spread shows up the week it happens, a physical-economy signal that doesn't wait for a quarterly report.

Six places. Millions more.

Every story here runs on free, open satellite imagery (four decades of Landsat), the public record that reaches back to the 1980s. What it can't do is reach back at high resolution, or update faster than about once a week.

That's the line where Planet begins: the largest daily Earth-observation archive ever built, at 3 metres. The history here is open data; the present, at this fidelity, is Planet's.

Built by Don Balanzat

An independent build for the love of the problem. Forty-year time-lapses: imagery © USGS/NASA Landsat via the Microsoft Planetary Computer, natural-color composites rendered per year, with signals (surface water, reclaimed land, standing forest) computed from spectral indices on the same scenes; Phoenix shows U.S. Census metro population. The closing comparison uses real Planet PlanetScope (Sandbox Data, CC-BY-NC) rendered through the Planet Insights Platform. Dollar figures are illustrative estimates from public sources: U.S. Bureau of Reclamation (Hoover Dam), the EU Deforestation Regulation, Dubai property records, and reported Aral Sea impacts.
