The goal of this study was to evaluate the utility of low-cost GPS receivers for field boundary mapping. Field tests were conducted using a low-cost receiver, a sub-meter receiver, and an RTK GPS system. Analyses focused on the accuracy of field area computations and quantification of lateral translation of field boundaries. The results showed that errors in field area computations were small. Lateral translations in field boundaries were also small and may be attributable as much to DGPS correction source as to receiver inaccuracies.
