Improved Fine-Scale Tropical Forest Cover Mapping For Southeast Asia Using Planet-Nicfi And Sentinel-1 Imagery, Feng Yang, Xin Jiang, Alan D. Ziegler, Lyndon Estes, Jin Wu, Anping Chen, Philippe Ciais

Geography

The accuracy of existing forest cover products typically suffers from “rounding” errors arising from classifications that estimate the fractional cover of forest in each pixel, which often exclude the presence of large, isolated trees and small or narrow forest clearings, and is primarily attributable to the moderate resolution of the imagery used to make maps. However, the degree to which such high-resolution imagery can mitigate this problem, and thereby improve large-area forest cover maps, is largely unexplored. Here, we developed an approach to map tropical forest cover at a fine scale using Planet and Sentinel-1 synthetic aperture radar (SAR) imagery …
