types; cloud and scan-line gaps; and scarce vegetation ground plots make producing such maps with
satellite imagery difficult. How can managers map tropical forest tree communities with satellite imagery
given these challenges? Here we describe a case study of mapping tropical forests to floristic classes with
gap-filled Landsat imagery by judicious combination of field and remote sensing work. For managers, we
include background on current and forthcoming solutions to the problems of mapping detailed tropical
forest types with Landsat imagery. In the study area, Trinidad and Tobago, class characteristics like deciduousness
allowed discrimination of floristic classes. We also discovered that we could identify most of
the tree communities in (1) imagery with fine spatial resolution of 61 m; (2) multiseason fine resolution
imagery (viewable with Google Earth); or (3) Landsat imagery from different dates, particularly imagery
from drought years, even if decades old, allowing us to collect the extensive training data needed for
mapping tropical forest types with ‘‘noisy’’ gap-filled imagery. Further, we show that gap-filled, synthetic
multiseason Landsat imagery significantly improves class-specific accuracy for several seasonal forest
associations. The class-specific improvements were better for comparing classification results; for in
some cases increases in overall accuracy were small. These detailed mapping efforts can lead to new
views of tropical forest landscapes. Here we learned that the xerophytic rain forest of Tobago is closely
associated with ultramafic geology, helping to explain its unique physiognomy.Helmer, E.H.
