@aaronjbecker.bsky.socialIn 1984 the western edge of Ankara fit in one corner of this frame. Today buildings cover nearly a third of it.
Ankara ran west along the valley: 1.7 million people in frame to 4.7 million.

@aaronjbecker.bsky.socialIn 1984 Gaziantep is barely visible against the brown hills. By the end it is a city of two million.
One Landsat frame a year, 1984 to 2026. No coastline and no river decided anything here.
@aaronjbecker.bsky.socialCanada is a near-even split: 36% forest, 35% tundra scrub and grass. Then it's water, 10% lakes plus 9% flooded vegetation. Only 0.3% is built. 10 m Sentinel-2 land cover, stacked by area.
@aaronjbecker.bsky.socialIn 1984 this stretch of Black Sea coast was empty hills. That white rectangle near the end is one of the largest airports on Earth.
Istanbul has spent forty years climbing north, one Landsat frame a year.
@aaronjbecker.bsky.socialThose bright green squares around Phoenix at the start are irrigated fields. Most of them are neighborhoods now.
One Landsat frame a year, 1984 to 2026. The population in frame went from 1.7 million to 5 million.
@aaronjbecker.bsky.socialWatch the bay. Antalya wraps the shoreline and pushes east until the flat land runs out and the mountains stop it.
One Landsat frame a year, 1984 to 2026. 270,000 people then, over 1.6 million now.
