T., Saatchi, Sassan (2018) IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, doi:10.1109/JSTARS.2018.2851606 Three types of data are provided: (1) Tabular data files (.csv) Plot-based estimates of aboveground biomass and lidar-derived metrics for calibration points of 1ha or 0.25ha (0.16ha in case relative tree coordinates were missing). TropiSAR- and AfriSAR-related data are provided in separate files. Further details about the data provided are given below. * abbreviations agb aboveground biomass DBH diameter at breast height H height wd wood density (obtained from the global wood density database; see Chave et al. 2009, Zanne et al. 2009 ) * information about data found in each of the .csv files Site one of the two TropiSAR (Nouragues or Paracou) or the four AfriSAR (Lope, Mabounie, Mondah or Rabi) sites Area_code single ID for area of interest, that can be of either 1ha (suffix 'h'), 0.25ha (suffix 'q') or 0.16ha (suffix 'c') Plot_code plot code of the area of interest (note that several areas of interest can belong to the same plot) Scale either 1ha, 0.25ha or 0.16ha depending on area of interest sw_x easting of the 'southwest' corner of the area of interest (in m; standard UTM coordinate system) sw_y northing of the 'southwest' corner of the area of interest (in m; standard UTM coordinate system) nw_x easting of the 'northwest' corner of the area of interest (in m; standard UTM coordinate system) nw_y northing of the 'northwest' corner of the area of interest (in m; standard UTM coordinate system) se_x easting of the 'southeast' corner of the area of interest (in m; standard UTM coordinate system) se_y northing of the 'southeast' corner of the area of interest (in m; standard UTM coordinate system) ne_x easting of the 'northeast' corner of the area of interest (in m; standard UTM coordinate system) ne_y northing of the 'northeast' corner of the area of interest (in m; standard UTM coordinate system) agb_fph aboveground biomass (expressed as a density, in Mg ha-1) using equation 4 in Chave et al. 2014 with wd, DBH and H derived from Feldpausch 2012 HD relationship for Central Africa cred_fph_2.5 lower bound of 95% credibility interval for agb_fph (in Mg ha-1) cred_fph_97.5 upper bound of 95% credibility interval for agb_fph (in Mg ha-1) agb_chv aboveground biomass (expressed as a density, in Mg ha-1) using equation 7 in Chave et al. 2014 with wd, DBH and H implicitly taken into consideration through the use of bioclimatic predictor E cred_chv_2.5 lower bound of 95% credibility interval for agb_chv (in Mg ha-1) cred_chv_97.5 upper bound of 95% credibility interval for agb_chv (in Mg ha-1) agb_loc aboveground biomass (expressed as a density, in Mg ha-1) using equation 4 in Chave et al. 2014 with wd, DBH and H derived from local HD relationships cred_loc_2.5 lower bound of 95% credibility interval for agh_loc (in Mg ha-1) cred_loc_97.5 upper bound of 95% credibility interval for agh_loc (in Mg ha-1) TCH mean top-of-canopy height derived from the canopy height model at 1m resolution (in m) H50 median height of the canopy height model at 1m resolution (in m) G20 gap fraction at 20 m, i.e. the proportion of area not occupied by crown at 20 m aboveground STDV standard deviation of the canopy height model at 1m resolution BA basal area (m2 ha-1) WD basal-area-weighted wood density (g cm-3) Ndens stem density (in stem ha-1) (2) Raster files (.tif files) Georeferenced digital terrain models (DTM) and canopy height models (CHM) at 1-m resolution are available upon request to the study site PIs: * Nouragues => Jérôme Chave (jerome.chave@univ-tlse3.fr) * Paracou => Grégoire Vincent (gregoire.vincent@ird.fr) * Lope, Mondah and Rabi => Sassan S. Saatchi (Sassan.S.Saatchi@jpl.nasa.gov) * Mabounie => Nicolas Barbier (nicolas.barbier@ird.fr) Maps of predicted agb were originally produced at 50-m resolution and then coarsened to 100-m and 200-m resolution through pixel aggregation by a factor 2 and 4, respectively (mean returned, no extension allowed). Overall, three maps of predicted agb are provided for each of the two TropiSAR (Nouragues, Paracou incl. Arbocel) and the four AfriSAR (Mabounie, Mondah, Lope and Rabi) sites. Note that "Arbocel" corresponds to PAR17 in the .csv and .shp files. Coordinate Reference Systems: (1) TropiSAR sites: WGS 84 / UTM zone 22N; (2) Mondah AfriSAR site: WGS 84 / UTM zone 32N; (3) other AfriSAR sites (Lope, Mabounie, Rabi): WGS 84 / UTM zone 32S (3) Vector files (.shp) Polygons corresponding to the location of calibration points of 1ha or 0.25ha (0.16ha in case relative tree coordinates were missing) are provided in order to further facilitate spatial data (e.g. CHM) extraction. Permanent plot georeferencing was refined after tree GPS coordinates were shifted to best-match the lidar-derived CHM. Three shapefiles are provided, corresponding to: (1) TropiSAR calibration points, (2) Mondah AfriSAR calibration points, and (3) calibration points for other AfriSAR sites (Lope, Mabounie, Rabi). Coordinate Reference Systems: (1) TropiSAR sites: WGS 84 / UTM zone 22N; (2) Mondah AfriSAR site: WGS 84 / UTM zone 32N; (3) other AfriSAR sites (Lope, Mabounie, Rabi): WGS 84 / UTM zone 32S
