abstract = "The mapping of vegetation and Land Cover (LC) is important for
research and for public policy planning but, in Brazil, although
diverse maps exist there are few studies comparing them. The
semiarid region of the Caatinga, in northeastern Brazil is an area
long neglected by scientific research and its vegetation is
diverse and relatively rich despite years of human occupation and
very little preservation effort. In this study we make a
comparison between the main maps made for the Caatinga from four
different sources: IBGE (Brazilian Institute of Geography and
Statistics), TCN (Third National Communication), ProBio (Project
for Conservation and Sustainable Use of Biological Biodiversity)
and MapBiomas. We also test these maps against well-known Land
Cover maps from ESA and NASA: ESAs GlobCover and Climate Change
Initiative (CCI) Land Cover, and NASAs MODIS MCD12Q1. This was
done on a sample area where many of the Caatingas vegetation
physiognomies can be found, using well-established Difference
metrics and the new SPAtial EFficiency (SPAEF) algorithm as they
present complementary viewpoints to test the correspondence of
mapped classes as well as that of their spatial patterns. Our
results show considerable disagreement between the maps tested and
their class semantics, with IBGEs and ProBios being the most
similar among all national maps and MapBiomas the most closely
related to global LC maps. The nature of the observed disagreement
between these maps shows they diverge not only in the application
of their classification systems, but also in their mapped spatial
pattern, signaling the need for a better classification system and
a better map of vegetation and land cover for the region.",
