Google Earth® provides free access to satellite images and has been used in several areas that
require cartographic information. The present study assessed the inconsistencies between
geo-referencing of livestock premises by GPS and the acquisition of geographic coordinates
by remote sensing (RS) images provided by Google Earth® in the Brazilian states of Bahia,
Distrito Federal, Minas Gerais and Parana. The overall mean and standard deviation of the
distances in the study were 30.98
±
19.89 m. The mean distance differences between the
two techniques were, for these states, 37.20
±
19.75 m, 28.38
±
17.38 m, 31.61
±
15.72 m,
28.43
±
24.30 m, respectively. Despite the fact that there is variation between the georeferencing
points using GPS and RS, geographical localization of health inspections should
be useful as long as the errors between the results of the two methodologies are considered.
