Global Peatland Fractional Coverage¶

Peatlands, as waterlogged terrestrial wetland ecosystems, store vast amounts of soil carbon and freshwater, playing a crucial role in the global carbon and hydrologic cycles. The Peat-ML dataset is a spatially continuous global map of peatland fractional coverage generated using machine learning models trained with climate, geomorphological, soil data, and remotely-sensed vegetation indices. Available peatland coverage maps from 14 regions, along with non-peatland ecoregions, were used to develop a statistical model with an average r-squared of 0.73 and errors of 9.11% (root mean square) and -0.36% (bias). The dataset is available in NetCDF format and published in 2021. For more information, you can access the associated research paper here.

The original datasets are available as NetCDF with a model accuracy with R² = 0.73, RMSE = 9.11%, MBE = -0.36%. You can download the Peat-ML Dataset (2021) here. Additional details are available in the paper Melton et al., 2022

// Load administrative boundaries for Indonesia
var admin1 = ee.FeatureCollection("projects/sat-io/open-datasets/geoboundaries/HPSCGS-ADM1");
var geometry = admin1.filter(ee.Filter.eq('shapeGroup', 'IDN'));

Map.centerObject(geometry, 4);
Map.setOptions("Hybrid");

var peat = ee.Image("projects/sat-io/open-datasets/ML-GLOBAL-PEATLAND-EXTENT")
    .clip(geometry)
    .unmask();

// Display the results
Map.addLayer(peat.clip(geometry),
