Dataset coding

The spatial data produced by Trends.Earth is in GeoTiff format. This is a widely supported format, so theese datasets can be used within QGIS as well as within any other GIS software.

If you wish to use Trends.Earth data outside of the tool itself, you will need to know how the data is coded. The tables below provide guidance on what the exact layers are that are produced by each analysis in Trends.Earth.

To see which of the below layers is contained within a Trends.Earth output file, use the load data tool. When you choose a file with that toool, it will show you a list of the layers within that file, as well as the band number for each layer.
