Resumo
The aim of this work was to correlate the navigation GPS (global position system) and
geodesic GPS with the optical level equipment to determine the most appropriate method to
obtain the quotas plan‐altimetry. The experimental data were collected at Catiuá farm, localized
in the Rio Paranaiba, Minas Gerais, Brazil; the data were obtained from two different GPS
receivers and one optical level equipment. The method used was pathway analysis. The data
were compared through t‐test. The geodesic GPS showed satisfactory results. On the order
hand, the greatest variability was observed when compared to the mean between the Garmim
model GPS (navigation) in relation with the optic level. We concluded that, when using the
optical level equipment as standard of altimetry measurements, the geodesic GPS is the most
suitable equipment.
