abstract = "Vegetation mapping of protected areas is a cornerstone of
conservation worldwide. Established in 1928 and covering over 1.4
million hectares, Hwange National Park (HNP) is the largest
natural reserve in Zimbabwe. In 1993, the sole comprehensive map
of its vegetation to date was produced and since then it has been
used in numerous research and conservation endeavours. Over the
last two decades, however, the parks vegetation changed, safari
areas and forest reserves were created at its edge and
high-positional accuracy data on a suite of species were
collected. To tend to contemporary mapping needs, in this article,
we present the 20132014 vegetation structure map of HNP and its
surroundings. It was produced by supervised classification of
Landsat-8 Operational Land Imager (OLI) images, indices derived
from these and the Landsat Tree Cover Continuous Field product.
Its accuracy was assessed statistically using samples collected
from high-resolution satellite imagery and basic ancillary field
data. Of its total pixels, 83.2% were correctly classified. Mean
omission and commission error were, respectively, 0.82 (0.740.90)
and 0.82 (0.720.89), and this similarity held on a per class
basis, indicating reliable area estimates. It was produced using
only freely available imagery and software.",
