Dargie GC, Lewis SL, Lawson IT, Mitchard ETA, Page SE, Bocko YE & Ifo, SA. 2017. 
Age, extent and carbon storage of the central Congo Basin peatland complex. 
Nature, doi:10.1038/nature21048

-------------------------------------------------------------------------------------
This is a set of files giving 4-class versions of the peat area and probability map in 
the original paper. They are designed for display use.

To create these files the two types of vegetation under which peat was found (hardwood
and palm-dominated swamp) were combined into a single Peat Swamp Forest class. 

Further, the speckle inherent in classification was reduced through the use of a 7x7 
majority filter, whereby the central pixel in a moving 7x7 window was replaced by the 
most common pixel type found in that window. 

The resolution was kept at 50 m, but effectively reduced by the level of zoom chosen
to create the resulting layers.

Country boundaries were added using the dataset made available by Diva-GIS, downloaded 
from http://www.diva-gis.org/Data

Projection and file details:

The files use a lat/long WGS-84 projection, with varying pixel sizes depending on 
resolution.
