The Google Earth Engine layer lets you display satellite imagery and geospatial datasets from Google’s vast catalog. These layers is useful in combination with thematic and event layers to enhance analysis. The following layers are supported:
Population density estimates with national totals adjusted to match UN population division estimates. Population in 100 x 100 m grid cells (from 2010).
Elevation above sea-level. You can adjust the min and max values so it better representes the terrain in your region.
Temperature: Land surface temperatures collected from satellite. Blank spots will appear in areas with a persistent cloud cover.
Precipitation collected from satellite and weather stations on the ground. The values are in millimeters within 5 days periods. Updated monthly, during the 3rd week of the following month.
Land cover: 17 distinct landcover types collected from satellites.
Nighttime lights: Lights from cities, towns, and other sites with persistent lighting, including gas flares (from 2013).
