Elevation: Metres above sea level
Nighttime lights: Lights from cities, towns, and other sites with persistent lighting, including gas flares (from 2013)
Population density: Population in 100 x 100 m grid cells (from 2010)
Temperature, population and land cover at any location.
Right-click on the layers to view more information, for example temperature and elevation.
In the top menu, click the Google Earth Engine layer icon.
