This folder contains 5 probability layers, the output of 1000 classification
runs using a random subset of training data to produce the peatland area

This folder contains 5 layers:
- Probability_HardwoodDominatedSwamp.tif
- Probability_PalmDominatedSwamp.tif
- Probability_Savanna.tif
- Probability_TerraFirmeForest.tif
- Probability_Water.tif
Each layer has pixel values from 0-1000, representing the number of times that class
was given as the most likely class for that pixel in 1000 maximum likelihood classifications
using a random subset of the training data.
For example, a value of 995 in the Probability_Water.tif file means that in 995 of the 1000
runs this pixel was mapped as 'water'. Conversely, a value of 4 in the Probability_Savanna.tif
would mean that that pixel was only mapped as savanna 4 times in the 1000 runs.
As an approximation, dividing these values by 1000 gives the probability that that pixel
contains a majority of vegetation of that class.
