- Probability map of vegetation types derived from 1,000 runs of a maximum likelihood classification using eight remote sensing products (three ALOS PALSAR; two SRTM-derived variables; three Landsat ETM+ bands) and jack-knifed selections of training data. Field observations show that peat underlies both hardwood tree-and palm-dominated swamp forest. PNG.
