Geologic maps were registered and geocoded with the prediction grid using the nearest neighbor resampling method. This method was used to avoid changing raster values. Systematic positional errors \citep{Samuel-RosaEtAl2014} were corrected using affine transformation (R-package vec2dtransf \citep{Carrillo2012}).
Inferior Sequence of the Serra Geral Formation. Composed mainly of basic igneous rocks (tholeiitic basalt and andesite);
Superior Sequence of the Serra Geral Formation. Composed mainly of acid igneous rocks (granophyric rhyolite and rhyodacite);
Botucatu Formation. Composed mainly of aeolian sandstones;
Caturrita Formation, is which composed mainly by fluvial sandstones;
Quaternary deposits of fluvial, alluvial, and colluvial origin.
The first land use map available was produced by manually digitizing land use data included in the topographic maps (scale of 1:) used to produce the more detailed pedological and geologic maps.
The most up-to-date land use map was prepared using high resolution orbital images (Quick Bird satellite). It covers the years of 2008 and 2009, and was prepared at a scale of 1: \citep{SamuelRosaEtAl2011a}.
