| contents | 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 Projection: Geographic Lat/Lon Geodetic Datum: WGS-84 Data type: Byte File type: Geotiff (LZW compression) Pixel size : 0.8 arcseconds × 0.8 arcseconds (approximately 25m × 25m at Equator) Pixel value: - 0 to 85: AGB in tons/ha - 100: dense forests mask - 160: flooded forests mask - 170: mangroves mask - 190: urban areas mask - 210: water bodies mask |
