Landsat free-data policy (2008)
In 2008 the USGS and NASA made the full Landsat image archive, dating to 1972, free to download. Before that, a single scene cost hundreds of dollars and the data was largely confined to government researchers.
Usage exploded; agriculture, water, and disaster agencies folded satellite data into routine operations.
It seeded a commercial remote-sensing industry—Planet's founders among them—that now sells what was once classified or paywalled.
Landsat established that broad open Earth data has civilian value. Planet's open TLE feed is the orbital-data cousin of that decision.
