Abstract:
This dataset gives estimates of the woody above-ground biomass (AGB) of the savannahs and woodlands of continental Africa and Madagascar at a 25 meters spatial resolution, obtained from the 2010 ALOS PALSAR mosaic produced by the Japanese Space Exploration Agency (JAXA).
AGB is estimated between 0 and 85 Mg.ha-1 following the methodology described in the referenced publication.
The following land cover classes have been masked:
- Dense forests and flooded forests, using classes 50 (Dense forests) and 160 (Flooded forests) of the ESA CCI Land Cover dataset: https://www.esa-landcover-cci.org/
- Mangroves, using the GMW (Global Mangrove Watch) dataset: https://www.globalmangrovewatch.org/
- Urban areas, using the HBASE (Human Built-Up and Settlement Extent) dataset: http://sedac.ciesin.columbia.edu/data/set/ulandsat-hbase-v1
- Water bodies, using the GSW (Global Surface Waters) dataset: https://global-surface-water.appspot.com/
The data can be used for a wide range of applications, from conservation to carbon accounting.
.
The dataset is divided into 10° × 10° tiles. The file names give the coordinates of the upper left corner of each tile (in degrees latitude and longitude).
An additional file is provided: AGB_Bouvet_QGIS_style.qml, which is a QGis style file to visualize the AGB dataset in the QGis software.
Year of estimate: 2010
