Global elevation map including buildings, 90m (Copernicus)

CopDEM COG (90 m)
land ESA ESA Copernicus
In plain English

What it measures. A height model of the Earth's surface at 90-metre detail, including the tops of buildings, infrastructure, and vegetation rather than just bare land.

How it's made. Created from Copernicus satellite radar observations and distributed worldwide as cloud-optimised image files at 90-metre resolution.

How & where you'd use it. A lighter, broad-scale option for terrain mapping, large-area flood and watershed studies, and global modelling where fine detail is not essential.
