Internet software programs aid in search for Amazonian geoglyphs

Ranzi, Alceu, Feres, Robert, Brown, Foster·2007·Eos, Transactions American Geophysical Union

Abstract

The Web‐based Google Earth software program recently has incorporated high‐resolution satellite imagery that facilitates the search for landscape expressions of past civilizations that we call geoglyphs. Since 2000, about 40 such geoglyphs have been observed in overflights above recently deforested pastures of southwestern Amazonia in eastern Acre State, Brazil [Ranzi and Aguiar, 2001; Ranzi, 2003; Ranzi and Aguiar, 2004]. These geoglyphs typically are circular or rectangular, on the scale of 100 meters or more, with bordering trenches 1–3 meters deep (Figure l). Carbon‐14 dating of charcoal associated with these geoglyphs indicates ages between 2500 and 1000 years B.P [Latini, 1998; Pärssinen et al., 2003].

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
