Center for Data Innovation: “NASA has released a dataset that includes more than a trillion precise measurements of the Earth’s height at various locations, including the height of glaciers and the height of the canopy of forests. NASA gathered the data, which includes the exact latitude and longitudes for a corresponding elevation, by shooting photons from a satellite 310 miles in space and recording how long it takes for the photon to bounce off the Earth and return to the satellite. This data can help researchers track the effects of the Earth’s warming climate and the health of forests…”
