Artificial Light
The dataset covers the world from 75 N to 65 S latitudes with 1500 grid size in a 6–cell set GEOTIFF format with a spatial resolution of 742 m per pixel. Nighttime images are produced daily. However, Elvidge et al. (2017) filtered out non-artificial light sources (eg. lightning, fishing boats, clouds) and they created a database of images (monthly and yearly) on the website of the dataset. The data used covers the years 2012-2019.
The dataset is ready to be used in GIS. Two different types are used: 1) extension “vcm-orm-ntl” (version in which VIIRS Cloud Mask, Outlier Removed and Nighttime Lights); 2) extension “Avg rade9".
