    Estimating mangrove above-ground biomass (AGB) in Sabah, Malaysia using field measurements, shuttle radar topography mission and landsat data
    (UMS, 2020) Charissa J. Wong; Daniel James; Normah A. Besar; Mui-How Phua
    We examined the use of Shuttle Radar Topography Mission (SRTM) data to estimate mangrove Above-ground Biomass (AGB) in Sabah, Malaysia. SRTM-DEM can be considered as Canopy Height Model (CHM) because of the flat coastal topography. Nevertheless, we also introduced ground elevation correction using a Digital Terrain Model (DTM) generated with GIS and coastal profile data. We mapped the mangrove forest cover using Landsat imagery acquired in 2015 with the supervised classification method (Kappa coefficient of 0.81).
