Predicted soil organic carbon stock at 30 m in t/ha for 0-100 cm depth global / update of the map of mangrove forest soil carbon
Description
This is an update of maps produced by Sanderman et al (2018). The improvements to the 3D spatial prediction include:
-
new updated global mangrove coverage map (contact Thomas Worthington),
-
new ALOS-based DEM of the world AW3D30 v18.04,
-
new radar ALOS-based PALSAR radar images of the world,
-
additional SOC points (ca 550) published in Rovai et al. (2018) used in model training (see gpkg file).
To open map in QGIS or similar, drag and drop the "mangroves_dSOC_0_100cm_30m.vrt" file. You can than add also the gpkg file contain the training points. A preview (WMS) of the predictions is available here.
Production steps (ensemble predictions using SuperLearner) are explained in detail at:
- R code: https://github.com/whrc/Mangrove-Soil-Carbon/ (see "R_code/GMW_mangroves_SOC_30m.R")
- Tutorial: "Predictive Soil Mapping with R"
